Description

Sanitary equipment and fixtures installed in water-related equipment including toilets, bathrooms, washrooms and kitchens, and water-related equipment including toilets, bathrooms, washrooms and kitchens, and control devices for equipment installed in water-related equipment and The present invention relates to a sterilizing agent containing live bacteria and a sterilizing method for sterilizing an object to be sterilized including a display device and the like.
Further, the present invention relates to a disinfectant and a disinfectant method used in a local cleaning device for a toilet seat with a hot water washer or used in a hot water circulation path of a bathtub, and more specifically, for a local cleaning nozzle and a nozzle pipe of the local cleaning device. Or, it relates to a sterilizing agent and a sterilizing method for a circulation type reheating pipe.

Water around toilets, bathrooms, washrooms, kitchens, etc. is also a place where not only mold but also various germs grow. Propagated germs are not only harmful because they give off a strange odor or become argentavis, but in the case of pathogens of infectious diseases, there is a risk that the infectious diseases will spread by daily use. In particular, in today's society, it is an urgent task to sterilize the places that are used on a daily basis and maintain a clean state in order to control the spread of infectious diseases.

Conventionally, chlorine-based sterilizing agents and the like have been widely used for disinfection and sterilization. However, since it is harmful to the human body, it is necessary to wash it to completely remove the residual chlorine-based disinfectant after use. Furthermore, since there is a pungent odor, the sterilization objects and sterilization methods that can be used are limited, such as requiring careful handling. In order to maintain a clean state, it is necessary to sterilize frequently and repeat cleaning.
A technique for an antibacterial resin in which sterilization is continuously performed by gradually dissolving and releasing an antibacterial agent in order to maintain a sterilized and clean state is disclosed (Patent Document 1). It has been shown that antibacterial resin moldings are used for local cleaning nozzles of toilets and warm water washing toilet seats that need to be kept clean even after sterilization. However, it is not desirable to use a disinfectant composed of a chemical substance mixed in the resin so as to come into contact with particularly sensitive skin or a local part of the human body, and there is a problem that the applicable object of the antibacterial resin is limited. Further, in order to disinfect the inside of the local cleaning nozzle and the inside of the pipe, the nozzle portion must be disassembled, the disinfectant must be poured into the local cleaning nozzle, and then the residual disinfectant must be completely cleaned and removed.
On the other hand, it is disclosed that an aerosol of a cleaning composition (Patent Document 2) consisting of soap that is less irritating to the skin and mucous membranes is sprayed on a cleaning nozzle of a warm water washing toilet seat to sterilize the bacteria. However, in the case of cleaning and sterilizing using a mild detergent, there is a problem that frequent spraying is required to maintain a clean state after sterilization.

The probiotic sterilizing agent which is the composition of the present invention is a sterilizing agent which is composed of probiotics and water and can further contain prebiotics which are nutrients, and is a probiotic which is the composition of the present invention. The probiotics of the disinfectant are Bacillus subtilis.

The sterilization method using the sterilizing agent of the present invention can be continuously sterilized by contacting the object to be sterilized as a liquid, a droplet or a gel. In the sterilization method by contact with the sterilization target, the sterilizing agent can be sprayed or applied to the outer surface of the sterilization target, or flowed or remained inside the sterilization target. Since the probiotic disinfectant is harmless to the human body, it can be used in places where the sensitive skin of the human body comes into contact, and it is not necessary to completely remove it after use. It can be done easily and reliably. Probiotic disinfectants can be used in contact with the skin to disinfect objects to be disinfected.

The object of sterilization of the present invention is a local cleaning nozzle of a toilet bowl, a main body of a toilet bowl, a lid of a toilet bowl, a toilet bowl cover, a bathtub, a reheating pipe for a bathtub, a washbasin main body, a washbasin bowl, and a kitchen sink main body. , And these drainage pipes around the water, and can be sterilized by spraying or applying to the outer surface of the sterilization target, or by a sterilization method that flows or remains inside the sterilization target.

Water supply facilities including toilets, bathrooms, washrooms, kitchens, etc. are facilities that are used on a daily basis, and are places where various bacteria remain due to daily use. Probiotic disinfectants containing live bacteria can be deodorized by the growth of good probiotic bacteria and the continuous suppression of the growth of germs that cause stinks, which is a cause of infectious diseases. It is possible to suppress the growth of pathogens and maintain a clean state after eradication. Probiotics are also used in pharmaceuticals and beverages, and since they are harmless to the human body, they can be used in any area that comes into contact with the skin or sensitive parts of the human body, regardless of the object to be sterilized. Therefore, it is not necessary to completely remove the residual component after the sterilization, and the probiotic sterilizing agent of the live bacterium remains, so that the sterilized clean state is continuously maintained. In this way, probiotics can be used to suppress the growth of harmful bacteria that are friendly to the environment and the human body and are harmful to the human body, and can be used for various sterilization targets, and the effect can be sustained. This is an effect not found in conventional disinfectants such as chlorine-based disinfectants and antibacterial resins.
The bactericidal action of the bactericidal agent of the present invention is known to be that Bacillus subtilis, which is a probiotic, has particularly high durability against heat and chemicals, and due to this excellent environmental resistance property, in the same place. Bacteria can be eradicated by suppressing the growth of various germs.
More specifically, the effect of the disinfectant of the present invention can be used for disinfecting the local cleaning nozzle of the local cleaning device because it can be used in a place where the sensitive skin of the human body touches. It is possible to perform local cleaning and local sterilization of the human body while sitting on the toilet seat. As described above, not only the sterilization of the local cleaning nozzle but also the local sterilization can be performed, which is a characteristic effect of the probiotic sterilizing agent which is not found in other sterilizing agents.
Further, since the disinfectant of the present invention is harmless to the human body, it can be used as a bathing agent to disinfect the inside of the circulation type reheating pipe of the bathtub while taking a bath. Bacillus subtilis, which is a probiotic sterilizing agent, has a characteristic not found in bacterial agents, and has the effect of enhancing the moisturizing property of the skin.

It is explanatory drawing of the sterilization of the local washing nozzle with the probiotic sterilizing agent in the warm water washing toilet seat apparatus which is one Embodiment of this invention.

Probiotics, which are also used in beverages and health foods, are gentle on the human body. It is a well-known function of probiotics. Water facilities including toilets, bathrooms, washrooms, kitchens, etc. are places where various germs remain due to daily use. When probiotics coexist in water-related equipment including toilets, bathrooms, washrooms, kitchens, etc., the good bacteria of probiotics multiply, causing harmful odors and infectious diseases. Propagation of various germs is suppressed and the bacteria are eradicated in a clean state. Probiotics are gentle on the human body, can be used where the skin and sensitive parts of the human body come into contact, and are environmentally friendly, so it is not necessary to completely remove residual components after sterilization and leave them behind. This makes it possible to maintain a clean state in which the probiotics of live bacteria are continuously eradicated.

The object to be sterilized by the probiotics sterilizing agent of the present invention is not particularly limited, but is not limited to water-related equipment including toilets, bathrooms, washrooms and kitchens, and water including toilets, bathrooms, washrooms and kitchens. It is suitable for disinfecting sanitary supplies and equipment installed in surrounding equipment, as well as control devices and display devices for equipment installed in water-related equipment. Toilet floors, walls, doors, toilet bowls, hot water washing toilet seats, heating toilet seats, etc., kitchen walls, floors, sinks, bathroom walls, floors, doors, bathtubs, washbasins, etc. Especially suitable for disinfecting drainage systems and the inside of pipes.
Here, the sanitary equipment refers to a movable item such as a bucket or a cleaning tool provided in the water supply facility, and the equipment indicates a fixed item. The control device, display device, and the like of the equipment installed in the water supply equipment refer to, for example, a warm water washing toilet seat of a toilet, a water heater of a bathroom or a kitchen, and the like.

In the sterilizing object of the present invention, the probiotic sterilizing agent is odorless, and the sterilizing effect is maintained by the action of probiotics. It is more suitable for water-related equipment.
Toilets in large commercial facilities have an unspecified number of users, and it is necessary to keep them clean and sterilized without frequent sterilization work.
In addition, in kitchen facilities, food residues and oil and fat components are constantly discharged on a daily basis, so not only hygienic sterilization but also fermented odors discharged by fermentation by various bacteria, ammonia generated in an anaerobic state, etc. Odor is generated and becomes a problem of bad odor in the surrounding area.
Since various facilities are adjacent to each other in a large facility, there are restrictions on the disinfectants that can be used, and disinfectants with a pungent odor cannot be used. There is a demand for a disinfectant that can be sustained. Therefore, a probiotic sterilizing agent that is odorless and has a long-lasting sterilizing effect is particularly suitable for sterilizing water-related equipment such as toilets and kitchens in large-scale commercial facilities and around drainage systems of kitchen equipment.

The present invention provides a sterilizing composition containing probiotics, which are live bacteria.
The present invention uses a disinfectant composition containing probiotics, which are live bacteria, and uses a water supply facility including a toilet, a bathroom, a washroom and a kitchen, and a water supply facility including a toilet, a bathroom, a washroom and a kitchen. It is intended to provide a method for sterilizing an object to be sterilized, such as a control device and a display device for sanitary goods, equipment, and equipment installed in a water supply facility. The probiotics of the present invention are Bacillus subtilis, and may be not only the Bacillus subtilis but also the same Bacillus bacterium. That is, the probiotics of the present invention may be one or more selected from the group including Bacillus subtilis, Bacillus licheniformis, Bacillus megaterium and Bacillus amyloliquefaciens. The concentration of Bacillus subtilis in the composition probiotic disinfectant is mass%, in the range of 1-2%.
The sterilizing action of the present invention can eradicate the growth of unwanted germs in the same place by suppressing the growth of coexisting germs due to the high environmental resistance generally possessed by Bacillus bacteria.

The probiotics used in the present invention can be grown using a known culture method such as Bacillus subtilis. It is also possible to use the obtained culture or the cells recovered from the culture as the probiotic sterilizing agent of the present invention. Additional operations such as heating and freeze-drying may be performed after culturing as long as the effects of the present invention are not impaired. The form of the probiotic sterilizing agent consisting of the culture or cells is, for example, solid (for example, bacterial powder, tablets, etc.), semi-solid, gel or liquid, as long as the intended effect of the present invention is not impaired. Any of these may be used, and a form that is easily dissolved in water at the time of use is preferable.

In carrying out the present invention, various substances can be blended in the probiotic sterilizing agent of the present invention as long as the intended effect of the present invention is not impaired. Examples of such are fragrances, pigments, dyes, thickeners, thickeners, preservatives, dispersants, solvents and the like.

Examples of the sterilization method include appropriately contacting the probiotic sterilizing agent of the present invention with the sterilizing target. The sterilized state can be maintained by continuous contact. Equipped in sanitary equipment, equipment and water supply equipment including toilets, bathrooms, washrooms and kitchens, and water supply equipment including toilets, bathrooms, washrooms and kitchens as targets for sterilization. The sterilization can be performed by spraying or releasing a liquid probiotics sterilizing agent on the outer surface of the control device and the display device of the equipment.
In the case of sterilization of the wastewater system, if there is a trap, it can be sterilized by administering it to the trap. Since the probiotic disinfectant is environmentally friendly and harmless to the human body, it may be sprayed, applied, or administered as it is. In particular, it is desirable that the probiotic disinfectant remains to maintain the disinfectant clean state.

In the case of a toilet, a probiotic sterilizing agent can be applied to the inside of a toilet bowl or the outer surface of a local washing nozzle of a warm water washing toilet seat by spraying or releasing to sterilize the toilet.
Probiotic disinfectants are particularly suitable for disinfecting local cleaning nozzles of warm water washing toilet seats. For the cleaning nozzle that is locally cleaned after defecation and is contaminated with sewage, a probiotics disinfectant is discharged to the local cleaning nozzle from a separately provided cleaning nozzle and applied, or the local cleaning nozzle is used. The flow path of the probiotics disinfectant can be switched and flowed inside the tube, and discharged from the local cleaning nozzle to disinfect.

Probiotic disinfectant solution for disinfecting toilet spaces such as toilet walls, floors and ceilings, and sanitary equipment and equipment that can be touched by human hands, control devices and display devices for equipment. A wide range of bacteria can be sterilized by spraying the drops as mist or the like. Because probiotic disinfectants are harmless to the human body, unlike conventional disinfectant sprays, they do not need to be unmanned during spray disinfection and have no adverse effects on adjacent facilities. It has the feature that various facilities can be used in the adjacent collective commercial facility. In addition, to disinfect a toilet seat with a warm water washing toilet seat, the skin is sprayed with a probiotics disinfectant mist with the lid closed after use in conjunction with the opening and closing of the lid of the warm water washing toilet seat. It is possible to sterilize the inside of the toilet bowl with a warm water washing toilet seat including the toilet seat that is directly touched.

A viscous gel in which a thickener or the like is added to a probiotic disinfectant can be in contact with the disinfectant for a certain period of time. For example, by applying a probiotic disinfectant gel around a drain pipe around water or a drain pipe, it is possible to continuously disinfect the metal or the pipe material without deteriorating it.

Hereinafter, suitable embodiments for carrying out the present invention will be described in detail. It should be noted that the embodiments described below show an example of a typical embodiment of the present invention, and the scope of the present invention is not narrowly interpreted by this.

In carrying out the present invention, various additive substances can be blended in the probiotic sterilizing agent of the present invention as long as the intended effect of the present invention is not impaired. Examples of such additive substances include fragrances, pigments, dyes, thickeners, thickeners, preservatives, dispersants and the like.

One embodiment as a probiotic preservative is a liquid in which the probiotics are dissolved in water and, if desired, can contain prebiotics as nutrients, as well as fragrances, pigments, dyes, By adding additives such as thickeners, thickeners, preservatives and dispersants, the probiotic disinfectant becomes a liquid, droplet and (viscous) gel, and comes into contact with the disinfectant. There are also methods such as spraying, coating, and continuous contact for a certain period of time depending on the state of the disinfectant or the disinfectant application.

In the case of a liquid as a probiotic disinfectant, the method of contacting the disinfectant is to apply the probiotic disinfectant to the outer surface of the disinfectant by spraying or releasing it. can. When the object to be sterilized is inside the nozzle and the drain pipe, the sterilization can be performed by flowing the probiotic sterilizing agent inside. Since the probiotic disinfectant is harmless to the human body, it can be flowed so as to come into direct contact with the skin or the like.

FIG. 1 is an explanatory diagram of sterilization of a local cleaning nozzle with a probiotic sterilizing agent in a warm water toilet seat device according to an embodiment of the present invention.
In the local washing device main body 1 of the warm water washing toilet seat shown in FIG. 1, hot water in a hot water tank 2 for storing hot water obtained by heating water from a water source 12 such as a tap water with a heater (omitted in FIG. 1) is connected by a pump 3. It is conveyed to the path 4 and ejected from the local cleaning nozzle 8 or the nozzle cleaning nozzle 7 that cleans the outer surface of the local cleaning nozzle 8 by the flow path switching unit 6. Between the pump 3 of the hot water passage 4 and the flow path switching portion 6, a disinfectant injection port 5 for supplying the probiotic disinfectant of the disinfectant tank 9 to the hot water passage 4 is provided. The probiotic disinfectant is conveyed from the disinfectant tank 9 to the disinfectant injection port 5 by the disinfectant supply means 11 via the check valve 10, and the nozzle cleaning nozzle 7 or by the flow path switching unit 6. It can be ejected from the local cleaning nozzle 8. The pump 3 and the disinfectant supply means 11 allow the probiotic disinfectant and hot water to be mixed in an arbitrary ratio at the disinfectant inlet 5.

As one form, the probiotic disinfectant conveyed to the disinfectant injection port 5 is ejected from the nozzle cleaning nozzle 7 to the outer surface of the local cleaning nozzle 8 by the flow path switching unit 6, and the local cleaning nozzle 8 is used. The outer surface of the nozzle can be sterilized with a probiotic disinfectant.

As one form, the probiotics disinfectant conveyed to the disinfectant injection port 5 is ejected from the local cleaning nozzle 8 by the flow path switching unit 6, and the inside of the pipe of the local cleaning nozzle 8 and the inside of the local cleaning nozzle 8 are inside. Can be sterilized from.
Further, it is also possible to perform local sterilization after defecation together with local washing with a probiotic sterilizing agent released from the local washing nozzle 8.

In the warm water washing toilet seat of the toilet, due to the structure of the local washing nozzle, the nozzle is contaminated by the sewage that has washed the local part after defecation. If this contaminated nozzle is left unattended, bacteria may grow not only on the outer surface of the nozzle but also on the inside of the nozzle. Due to concerns about the cleanliness of the nozzle, many people do not use the cleaning nozzle in the warm water washing toilet seat of public toilets.
Conventionally, cleaning of the local cleaning nozzle has been performed by flushing water or hot water from the local cleaning nozzle after cleaning the local area after defecation. Further, in the warm water washing toilet seat provided with the nozzle for cleaning the nozzle, the outer surface of the nozzle for local cleaning can be washed with water or warm water discharged from the nozzle for cleaning the nozzle after cleaning the local part after defecation. However, sterilization of the nozzle is not sufficient with warm water alone, and sterilization with a sterilizing agent is desired. No disinfectant could be used because it had to be removed.

In one embodiment of the present invention, since the probiotics are harmless to the human body, it is not necessary to remove the remaining probiotic disinfectant, and the probiotics can be used for disinfecting the local washing nozzle of the warm water toilet seat. Further, it is possible to disinfect the inside of the pipe and the inside of the local cleaning nozzle by flowing it not only on the outer surface of the local cleaning nozzle but also inside the pipe of the local cleaning nozzle. In addition, after defecation, the human body can be locally washed and locally sterilized while sitting on the warm water washing toilet seat. As described above, it is a feature of the probiotic sterilizing agent that other sterilizing agents do not have the ability to sterilize not only the local cleaning nozzle but also the local sterilization.

In addition, as a method of disinfecting the entire toilet bowl, in conjunction with the opening and closing of the lid of the toilet bowl with a warm water washing toilet seat, after use, spray the droplets of the probiotics disinfectant as mist etc. with the lid closed. It is possible to completely sterilize the inside of the toilet bowl with a warm water washing toilet seat. For example, even if a probiotic disinfectant remains on the surface of the toilet seat after spray disinfection of the toilet bowl, probiotics are not only harmless to contact with human skin, but also for disinfection for medical use. Because it is used, it can also be expected to have a sterilizing effect on the buttocks and local areas.

In order to suppress the growth of germs that cause offensive odors, such as tools, appliances, devices, walls, floors, drainage outlets, and inside drainage pipes, which are installed in water supply facilities including toilets, bathrooms, washrooms, and kitchens. It can be sterilized by spraying or applying a probiotics sterilizer.

By adding a thickener or the like to a probiotic disinfectant to form a viscous gel, it can be used for a purpose different from that of a liquid. In the viscous gel, a certain amount of probiotic disinfectant is continuously released for a certain period of time, and it is possible to disinfect various germs that cause slime around the drain outlet and in the drain pipe. Unlike chlorine-based slime removers, probiotic disinfectants are odorless and can be used continuously without altering the metal or pipe material.
For example, after cooking, a probiotic disinfectant is administered into the grease trap (grease trap) of the drainage system of the kitchen or kitchen equipment and left overnight to suppress the growth of germs that cause offensive odors. can do.
As described above, the probiotic sterilizing agent is a sterilizing agent characterized in that it is odorless and does not deteriorate the metal or the like, so that it can maintain a sterilizing and clean state by leaving it.

As a form of utilization in which the probiotics disinfectant is harmless to the human body and comes into contact with the human skin, for example, the probiotics disinfectant is put in a bathtub and used as a bathing agent, and not only the disinfectant in the bathtub but also the disinfectant is used. , It is possible to sterilize the inside of the reheating pipe connected to the bathtub.

Examples will be described in detail below. The examples are one aspect of the present invention, and the technical scope of the present invention is not limited to the description in the examples.
As described above, the probiotic sterilizing agent which is the composition of the present invention is a sterilizing agent consisting of probiotics and water (probiotic sterilizing agent), and is the probiotic sterilizing agent of the present invention. Probiotics are Bacillus subtilis.
Hereinafter, the probiotics used in the examples are Bacillus subtilis (Seti Co., Ltd., 5 billion cfu / g).
The content of Bacillus subtilis in the examples is 1% by mass with respect to the total probiotic disinfectant, and the rest is water.
Further, in the sterilization method that touches the skin of the human body, it is preferably 0.1% or less.

Deodorant test 1. Test method In a kitchen facility in a large facility equipped with Gristrap, the odor near Gristrap was collected and gas component analysis was performed by gas chromatography (GC) and gas chromatography mass spectrometry (GC-MS). , The difference in the odor components and their amounts before and after sterilization was investigated and the sterilization effect was verified.

2. 2. Odor collection place Near the grease trap in the kitchen facility of a large commercial facility (hereinafter referred to as place A)
Near the grease trap in the hotel kitchen facility (hereinafter referred to as location B)

Example 1
In the kitchen facility equipped with the grease lap in the large facility of the place A, the odor near the grease lap is collected, the odor component adsorbent after the odor collection is extracted with diethyl ether, and the ether phase is 0.2 ml. After concentrating to, gas chromatography (GC: Shimadzu GCMS-QP2020) and gas chromatography-mass spectrometry (GC-MS: Nippon Denshi JMS-Q1000GC) were used to analyze the gas components, and the odor components before and after sterilization were detected. The change in the amount was investigated and the eradication effect was verified. After collecting the odor after the cooking work on the test start day, the content of Bacillus subtilis, which is a probiotic, is 1% by mass with respect to the total probiotic disinfectant, and the rest is a probiotic consisting of water. 300 ml of Tix disinfectant was added to the grease lap. After the cooking work was completed every day, 300 ml of the probiotic disinfectant was repeatedly added to the grease trap, and 30 days after the start of the test, the odor was collected and analyzed in the vicinity of the grease trap as on the test start date.

Example 2
After collecting the odor after the cooking work on the test start day in the kitchen facility equipped with the grease lap in the large facility of the place B, the content of Bacillus subtilis, which is a probiotic, is added to the entire probiotic disinfectant. On the other hand, 300 ml of a probiotic disinfectant consisting of 1% by mass and the rest was added to Gristrap was added. After the cooking work was completed every day, 300 ml of the probiotic disinfectant was repeatedly added to the grease trap, and 37 days after the start of the test, the odor was collected and analyzed in the vicinity of the grease trap as on the test start date.
Table 1 shows the results of GC-MS analysis of Examples 1 and 2 below. The numerical value is the standardized peak intensity of each component.

ＧＣ－ＭＳ分析では、油脂の酸化物の２、４－デカジエナール（酸化臭）と、油が腐敗した際に発生する腐敗臭の酪酸と、不快臭となる吉草酸、カプロン酸、及び長鎖カルボン酸とが検出された。実施例１では、試験開始前に比べ試験開始３０日後に、酸化臭の２、４－デカジエナールで４１％、腐敗臭の酪酸で４０％の減少が得られた。実施例２では、試験開始前に比べ試験開始３７日後に、腐敗臭の酪酸で８８％の大幅な減少が得られた。以上の試験結果より、実施例１、２のいずれもプロバイオティクス除菌剤による消臭効果が実証され、また、試験開始３０日以降でもその消臭効果が持続していることが確認された。異臭の発生を防ぐために、従来では毎日の調理作業終了後に、グリストラップの内容物を除去して洗浄する必要があったが、プロバイオティクス除菌剤を投与するだけで、除菌消臭できることが分かった。特に、大型施設内の厨房施設では定常的に食物残差や油脂成分が排出されており、このような排出状況下で除菌、消臭効果が維持されることは、実用上大変意義があり、本発明のプロバイオティクス除菌剤の特徴である。

In the GC-MS analysis, 2,4-decadienal (oxidized odor), which is an oxide of fats and oils, fatty acid, which is a putrid odor generated when oil rots, and valeric acid, caproic acid, and long-chain carboxylic acid, which are unpleasant odors. Acid was detected. In Example 1, 30 days after the start of the test, a 41% reduction in the oxidative odor of 2,4-decadienal and a 40% reduction in the putrid odor of fatty acid were obtained as compared with before the start of the test. In Example 2, a significant reduction of 88% in the putrid odor of fatty acid was obtained 37 days after the start of the test as compared with before the start of the test. From the above test results, it was confirmed that the deodorizing effect of the probiotic disinfectant was demonstrated in both Examples 1 and 2, and that the deodorizing effect was maintained even after 30 days from the start of the test. .. In the past, in order to prevent the generation of offensive odors, it was necessary to remove and clean the contents of the grease trap after the end of daily cooking work, but it is possible to disinfect and deodorize simply by administering a probiotic disinfectant. I understood. In particular, food residues and oil and fat components are constantly discharged in kitchen facilities in large facilities, and it is very significant in practice that the sterilization and deodorizing effects are maintained under such discharge conditions. This is a feature of the probiotic sterilizing agent of the present invention.

Kitchen drainage water quality test Example 3
Wastewater from the grease lap of location A is collected, and the content of Bacillus subtilis, which is a probiotic, is 1% by mass with respect to the total probiotic disinfectant, and the rest is a probiotic extermination consisting of water. The effect of administration of 300 ml of the fungal agent on Gristrap on the quality of wastewater was investigated in comparison with the wastewater before the start of the test. The probiotic disinfectant was continuously administered after the completion of daily cooking work in the same manner as in Example 1, and the drainage was tested 3 months and 6 months after the start of the test.
The biochemical oxygen requirement (BOD) of wastewater, the nitrogen content indicating the amount of organic substances and ammonia related to odor generation, and the amount of normal hexane extract substance indicating the amount of oil mixed in wastewater are set in 21 and 45 of Japanese Industrial Standards K0102. Table 2 shows the results of analysis by the method specified and the method listed in Appendix 4 of Notification No. 64 of the Environment Agency of 1974.

試験開始前の厨房排水には、グリストラップ処理後も臭気発生に関係する有機物やアンモニア量を示す窒素含有量と共に排水に混入する油が多く含まれることが分る。従来の合成洗浄剤を用いて洗浄を行った場合には、このような有機物質や油は分解されることなく、水に可溶化され排出されることによって、環境汚染に繋がることが分かる。一方、プロバイオティクス除菌剤を毎日の調理作業終了後に投与すると、試験開始３ヵ月及び６ヵ月には窒素含有量及びノルマルヘキサン抽出物質量が減少しており、プロバイオティクスによって排水の油脂成分が分解されていることが明らかになった。すなわち、プロバイオティクス除菌剤は環境負荷に繋がる物質を分解する作用も有しており、従来の合成洗浄剤にない作用効果を有することが実証された。

It can be seen that the kitchen wastewater before the start of the test contains a large amount of oil mixed in the wastewater as well as the nitrogen content indicating the amount of organic matter and ammonia that are related to the generation of odor even after the grease trap treatment. It can be seen that when cleaning is performed using a conventional synthetic detergent, such organic substances and oils are not decomposed but are solubilized in water and discharged, which leads to environmental pollution. On the other hand, when the probiotic disinfectant was administered after the daily cooking work, the nitrogen content and the amount of normal hexane extract decreased 3 months and 6 months after the start of the test. It became clear that was disassembled. That is, it was demonstrated that the probiotic disinfectant also has an action of decomposing substances that lead to an environmental load, and has an action effect that conventional synthetic detergents do not have.

Sterilization test of toilet seat and local cleaning nozzle Example 4
The content of Bacillus subtilis, which is a probiotic, on the outer surface of the toilet seat and the local cleaning nozzle is 1% by mass with respect to the total probiotic disinfectant, and the rest is 1 probiotic disinfectant consisting of water. It was sprayed once a day every day, and the number of colonies in which each bacterium was cultured 2 months after the start of the test was measured, and the sterilization effect was examined by comparison with that before the start of the test.
The outer surface of the toilet seat and the local washing nozzle was wiped off with a cotton swab, and 100 μL of the sample solution was taken using a micropipette and added to various media on a 90 mm flat plate. After that, it was spread and cultured in a thermostat. The culture conditions (medium) of the test bacteria were 35 to 37 ° C. for 48 hours for general bacteria (SCD) and Escherichia coli (DESO), and 20 to 25 ° C. for 96 hours for fungi (Saburo). After culturing, the number of colonies is measured, the number of observed colonies is confirmed, and the sterilization effect is evaluated in the following three stages and shown in Table 3.

表３より、便座及びノズルともプロバイオティクス除菌剤の噴霧によって、試験開始２か月後に大腸菌、一般細菌及び真菌の増殖の抑制が確認された。特に、一般細菌や真菌に対して大きな除菌効果が得られた。局部洗浄ノズルは排便使用時に洗浄汚水による汚染があり、プロバイオティクス除菌剤を噴霧する以外には洗浄等行っておらず、プロバイオティクス除菌剤を噴霧するだけで、清浄な状態を維持できることが確かめられた。
本局部洗浄ノズルの外面の除菌は、図１に示す温水洗浄便座の局部洗浄装置において、除菌剤注入口５に搬送されたプロバイオティクス除菌剤が、流路切替部６によってノズルクリーニング用ノズル７から局部洗浄ノズル８の外面に噴出させる上記の実施形態に相当するものである。

From Table 3, it was confirmed that the growth of Escherichia coli, general bacteria and fungi was suppressed 2 months after the start of the test by spraying the probiotic disinfectant on both the toilet seat and the nozzle. In particular, a large sterilizing effect was obtained against general bacteria and fungi. The local cleaning nozzle is contaminated with cleaning sewage when using defecation, and it is not cleaned except by spraying the probiotic disinfectant, and it maintains a clean state just by spraying the probiotic disinfectant. It was confirmed that it could be done.
To disinfect the outer surface of the local cleaning nozzle, the probiotics disinfectant conveyed to the disinfectant injection port 5 is nozzle-cleaned by the flow path switching unit 6 in the local cleaning device of the warm water washing toilet seat shown in FIG. It corresponds to the above-described embodiment in which the nozzle 7 is ejected from the nozzle 7 to the outer surface of the local cleaning nozzle 8.

Local cleaning Nozzle tube internal sterilization test Example 5
Before starting the test, the local cleaning nozzle is disassembled, a sample is collected from the inside of the nozzle tube with a cotton swab in the same manner as in Example 4, and then the local cleaning nozzle is assembled, and the content of Bacillus subtilis, which is a probiotic, is probiotics. The probiotic disinfectant, which was 1% by mass with respect to the total disinfectant and the rest consisted of water, was diluted to 1/10 and released from a local washing nozzle to disinfect. However, the sterilization by spraying on the outer surface to the local cleaning nozzle performed in Example 4 was not performed. After washing with warm water after defecation, the flow path switching unit 6 in FIG. 1 switched to a probiotic disinfectant instead of hot water and discharged it from the local washing nozzle 8. Two months after the start of the test, the local cleaning nozzle was disassembled, collected from the inside of the nozzle tube with a cotton swab, and subjected to a bactericidal test in the same manner as in Example 4, the number of observed colonies was confirmed, and the sterilization effect was shown in the following 3 It is evaluated in stages and shown in Table 4.

局部洗浄ノズルの管内部に大腸菌や一般菌が検出されたことより、排便後の使用による汚染によって、局部洗浄ノズルの外面だけでなく、ノズル管内部も汚染されていることが分かった。
プロバイオティクス除菌剤を局部洗浄ノズル管に流動、放出させることによって、試験開始２ヵ月後にはノズル管内部から大腸菌や一般雑菌とも検出されず、局部洗浄ノズル管内部まで除菌されることが確認された。
プロバイオティクスは人の肌や敏感な局部に接しても無害であるために、このようにプロバイオティクス除菌剤を局部洗浄ノズル内部に流動させ、ノズルから放出させるような除菌方法が可能である。このような人の肌や敏感な局部に接するような除菌方法は、従来の除菌剤を用いた除菌方法にない、プロバイオティクス除菌剤に特徴的な除菌方法である。

From the fact that Escherichia coli and general bacteria were detected inside the tube of the local cleaning nozzle, it was found that not only the outer surface of the local cleaning nozzle but also the inside of the nozzle tube was contaminated due to contamination by use after defecation.
By flowing and releasing the probiotic disinfectant into the local cleaning nozzle tube, Escherichia coli and general germs are not detected from the inside of the nozzle tube 2 months after the start of the test, and the inside of the local cleaning nozzle tube can be disinfected. confirmed.
Since probiotics are harmless even if they come into contact with human skin or sensitive local areas, it is possible to disinfect the probiotic disinfectant by flowing it inside the local cleaning nozzle and discharging it from the nozzle. Is. Such a sterilization method that comes into contact with human skin or a sensitive local area is a sterilization method characteristic of probiotic sterilization agents, which is not found in conventional sterilization methods using sterilization agents.

Sterilization test inside the reheating device piping of the bathtub Example 6
The content of the probiotic bacillus bacillus in the uncleaned bathtub 300L of the circulating reheating device pipe is 0.1% by mass with respect to the total probiotic disinfectant, and the rest. 10 ml of a probiotic disinfectant consisting of water is administered as a bathing agent, and after bathing, the hot water in the bathtub is drained. After repeating the bacterial test of the sample collected with a cotton swab from the inside of the water supply port of the reheating device before the start of the test and the same bathing once a day for 30 days, the water supply port of the reheating device A bacterial test is performed on a sample collected from the inside, the number of observed colonies is confirmed, and the eradication effect is evaluated in the following three stages and shown in Table 5.

循環式の追い焚き器の場合には、人の垢やその他の汚れもお湯と一緒に配管内に吸い込んでいるため、配管内部は汚れが付着する。実際、循環式の追い焚き器給水口から一般細菌が検出され、循環式の追い焚き器の配管内部で雑菌が繁殖していることが示唆される。
一方、プロバイオティクス除菌剤を入浴剤として入浴時に使用するだけで、試験開始３０日後には、浴槽の追い焚き器の給水口から一般細菌は検出されなくなった。
従来は、追い焚き器配管内部の除菌は管材を変質させない除菌剤を用いて洗浄する必要があった。一方、プロバイオティクス除菌剤の場合には入浴剤として通常の入浴使用で、浴槽の追い焚き器配管内の除菌が確認された。このように浴槽に直に入れて、入浴剤と同時に除菌剤として作用することは、人に無害であり、管材を変質させないプロバイオティクス除菌剤の特徴を活かした除菌方法である。
実施例７
浴槽３００Ｌにプロバイオティクスである枯草菌の含有量がプロバイオティクス除菌剤全体に対して質量％で０．１％であり、残りは水からなるプロバイオティクス除菌剤１０ｍｌを入浴剤として投与し、入浴後、その角層水分量をプロバイオティクス除菌剤を投与しないお湯への入浴の場合と比較した。肌の角層水分量はキュートメーター（ＭＰＡ５８０）にコルネオメータープローブを用いて、被験部位（へその左右の腹部それぞれ１箇所）の角層水分量を測定し平均した。角層水分量測定では、角層水分の入浴後１、２、３時間後経時的な変化を測定し、プロバイオティクス除菌剤を投与した場合と投与しないお湯の場合との比をそれぞれ５回測定して平均値を表６に示す。

In the case of a circulation type reheating device, human dirt and other dirt are also sucked into the pipe together with hot water, so dirt adheres to the inside of the pipe. In fact, general bacteria are detected from the water supply port of the circulation type reheating device, and it is suggested that various bacteria are propagated inside the piping of the circulation type reheating device.
On the other hand, only by using the probiotic disinfectant as a bath agent at the time of bathing, general bacteria were no longer detected from the water supply port of the reheating device of the bathtub 30 days after the start of the test.
Conventionally, it has been necessary to clean the inside of the reheating device pipe with a sterilizing agent that does not deteriorate the pipe material. On the other hand, in the case of the probiotic disinfectant, it was confirmed that the disinfectant in the reheating device pipe of the bathtub was used as a bath agent in normal bathing. Putting it directly in the bathtub and acting as a disinfectant at the same time as the bath salt is a disinfectant method that takes advantage of the characteristics of the probiotic disinfectant that is harmless to humans and does not deteriorate the tube material.
Example 7
The content of Bacillus subtilis, which is a probiotic, in 300 L of the bathtub is 0.1% by mass with respect to the total amount of the probiotic sterilizer, and the rest is 10 ml of the probiotic sterilizer consisting of water as a bathing agent. After administration and bathing, the water content of the stratum corneum was compared with that of bathing in hot water not administered with a probiotic disinfectant. The water content of the stratum corneum of the skin was averaged by measuring the water content of the stratum corneum at the test site (one each on the left and right abdomen of the navel) using a corneometer probe on a cute meter (MPA580). In the measurement of the amount of water in the stratum corneum, the change in the water content of the stratum corneum over time is measured 1, 2 and 3 hours after bathing, and the ratio between the case where the probiotics sterilizing agent is administered and the case where the hot water is not administered is 5 respectively. Table 6 shows the average value measured once.

入浴後直後（表６ 入浴後の経過時間０）は入浴前に比べ、プロバイオティクス除菌剤を投与した場合及び投与しない場合のいずれの場合も角質水分量は減少し、その後、時間の経過とともに増加し入浴前の角質水分量に近づいた。プロバイオティクス除菌剤を投与しないお湯への入浴では、入浴後直後の減少から元の角質水分量への戻りは遅く、入浴後３時間経過しても入浴後直後からわずかに増加しただけだった。一方、プロバイオティクス除菌剤を投与した入浴の場合には直ちに元の角質水分量へ戻った。このため、表６に示すように、入浴後１時間では角質水分量比が大きくなった。その後、経過時間に従って角質水分量比は小さくなった。
以上のことより、プロバイオティクス除菌剤を入浴剤として投与した場合には、投与しないお湯への入浴の場合に比べて角質水分が保たれ保湿効果が確認された。
プロバイオティクス除菌剤は、入浴しながら浴槽や循環式追い焚き配管内部を除菌するだけでなく肌の保湿性を高める入浴剤としての効果があることが分かる。

Immediately after bathing (Table 6 elapsed time after bathing 0), the amount of keratin water decreased with and without probiotics sterilizing agent compared with before bathing, and then the passage of time. It increased with time and approached the amount of keratin water before bathing. When bathing in hot water without probiotic disinfectant, the return to the original keratin water content was slow from the decrease immediately after bathing, and even 3 hours after bathing, it increased only slightly immediately after bathing. rice field. On the other hand, in the case of bathing with a probiotic disinfectant, the original keratin water content was immediately restored. Therefore, as shown in Table 6, the keratin water content ratio increased 1 hour after bathing. After that, the keratin water content ratio decreased with the elapsed time.
From the above, it was confirmed that when the probiotic disinfectant was administered as a bath agent, the keratinous water was retained and the moisturizing effect was confirmed as compared with the case of bathing in hot water without administration.
It can be seen that the probiotic disinfectant is effective as a bath agent that not only disinfects the inside of the bathtub and the circulating reheating pipe while taking a bath, but also enhances the moisturizing property of the skin.

It is necessary to keep the control device, display device, etc. of the equipment to be sanitized and clean. For this reason, the members used for the water supply equipment and the drainage system have been used with consideration given to the chemical resistance to the disinfectant, especially the chlorine-based disinfectant. However, the use of probiotic disinfectants, which have no environmental impact, broadens the range of material choices, and eliminates the need for conventional residual disinfectant cleaning, leading to water resource savings and industrial resources. Contribution is also great.
Grease traps that collect food residues and oils and fats discharged from large kitchen facilities require regular cleaning. If this cleaning is insufficient, the fermentation odor discharged by the fermentation action by microorganisms and the odor such as ammonia generated in an anaerobic state are generated, which causes a problem of bad odor in the surroundings. In particular, kitchens in large commercial facilities require frequent cleaning and cleaning, and if the clean state after sterilization and deodorization is maintained continuously, cleaning costs and labor costs will be reduced. Further, since various facilities are adjacent to each other in a large facility, it is desired that the disinfectant used is odorless, harmless to the environment and the human body, and has a long-lasting disinfectant effect. The probiotic sterilizing agent of the present invention has no environmental load, is harmless to the human body, can reduce food residues discharged from kitchen facilities and the rotting odor of oil and fat components, and its sterilizing effect is maintained. It can be used for sterilization and deodorization of various objects, and it can be said that it has great potential for industrial use.
