The present invention relates to a method for producing a decomposition promoting material.

2. Description of the Related Art Conventionally, diverse and complex organic substances produced on the earth are fermented and decomposed by microorganisms from ancient times to fertilize soils, or to fertilize rivers, lakes and oceans, and to produce new plants and animals. It is the basis for the creation of living things. By repeating the generation and reduction of such organic substances, it has created and developed the great nature on the earth. Conventionally, in agriculture, organic matter has been combined and deposited or stacked, naturally fermented, and composted.

[0003] However, in recent years, human society has considered that organic materials are valuable resources that can be used as various organic materials such as food and wood, and that unused waste such as livestock excreta, plant residues, livestock residues, food residues, and garbage are used. While the former were treated with great care, the latter was regarded as unnecessary for human society and simply incinerated or disposed of. As a result of incineration or disposal of unused waste for many years, ignoring the production and reduction of organic matter in the natural world, the natural environment on the earth is destroyed, and the fertility of agricultural land is reduced. And have caused pollution causing lakes and marshes and marine pollution.

[0004] For this reason, not only industry, but also agriculture and livestock industry, it is required to improve the constitution in an environmental conservation type. The waste generated by these industrial activities is referred to as industrial waste, and food residues (garbage), other plant and animal residues, manure and sludge generated from general human and social life. Unused organic matter in the natural environment and living environment as general waste,
There has been a strong demand for environmentally-friendly treatments so as not to degrade public health.

[0005] In recent years, in Japan, chemical fertilizer agriculture has become widespread for about half a century, and as a result, the agricultural soil of Japan has become deficient in organic fertilizers and microorganisms. The decline in fertility, reduced yields of crops, and reduced vulnerability to cold damage and pests began to raise concerns about the future of Japanese agriculture. Therefore, it is necessary to promote the environmental conservation type agriculture and livestock industry in the future, and it is necessary to immediately improve the soil in order to reinforce the strength of the declining agricultural land. As a result, the importance of applying an appropriate amount of organic matter to agricultural land and soil has been reviewed, and there has been a strong demand for the development and utilization of composting and recycling techniques for organic matter.

Therefore, in recent years, techniques have been developed in various fields to detoxify or reuse organic substances, which have been regarded as harmful wastes, by fermentation treatment with microorganisms. The direction of the development was to use materials such as feed, mainly composting. In addition, with the conventional composting technology, microorganisms and fungi that rapidly ferment and decompose organic substances are developed, combinations of microorganisms and fungi that are suitable for the decomposition of target organic substances are developed, and fermentation is promoted. The mainstream was to develop fermentation facilities that could adjust the fermentation conditions such as temperature and air for the fermentation.

[0007] However, there is a limit to the method of fermenting and decomposing such complex organic matter having various components only by the decomposing activity of microorganisms such as fungi. Not satisfied. First, the period required for the fermentation decomposition treatment is too long. When trying to ferment and decompose organic matter by the decomposing activity of microorganisms such as fungi, humans can only add powerful fungi or maintain environmental conditions where those microorganisms are easily active, and by what time and how much Whether it is fermented or decomposed depends on the activity of the microorganism. Therefore,
Even if the organic matter is put into a fermenter and the air and temperature conditions are adjusted to be the best, it usually takes about 10 to 12 days for the primary fermentation and about 7 to 14 days for the secondary fermentation. That is, it usually takes about 20 to 25 days to ripen an organic fertilizer even if it is in a hurry. Therefore, various approaches have been studied to ferment and decompose organic matter in a shorter period of time.

Secondly, when a fermentation decomposition method using microorganisms is employed, if the fermentation is an anaerobic fermentation, a strong odor is generated. Until shifting to aerobic fermentation, the generation of offensive odors cannot be prevented. For this reason, it is very difficult to prevent odor pollution.

Therefore, the present inventor has made intensive research and development with the aim of performing fermentative decomposition treatment of various and complicated organic substances in a shorter time than before and with the odor suppressed as much as possible. As a result, acidification to suppress the odor of the organic matter to be treated, use of various enzymes to improve degradability and fermentability, and select microorganisms suitable for fermentation and decomposition, I recalled using it. However,
Investigation of the prior art revealed that the invention using an enzyme for improving the degradability of agricultural waste and garbage or for promoting fermentation is disclosed in Japanese Patent Nos. 2655960 and 292.
No. 0259 was confirmed.

[0010] The former Patent No. 2655960 discloses that an agglomerate of fibrous solid organic waste is mixed with a fibrinolytic enzyme which is a mixture of cellulase and hemicellulase in the presence of water, hydrolyzed, and then aerobic. A method for composting fibrous solid organic waste, wherein fermentation is performed. The gist of the present invention is that aerobic fermentation is performed after fibrous solid organic waste is hydrolyzed with a fibrinolytic enzyme as pretreatment. It is known that cellulase and hemicellulase are fibrinolytic enzymes, and it is easy for those skilled in the art to use the known fibrinolytic enzyme for decomposing fibrous solid organic matter. Therefore, the present invention is characterized in that aerobic fermentation is performed after enzymatic decomposition. However, raw garbage, which is the raw material for compost,
Organic wastes such as manure, sludge, livestock residues, and plant residues usually contain not only fibrous solid organic matter but also complex and diverse components such as starch, protein, and fat. Is the feature. Sorting such municipal waste by component is practically almost impossible. Therefore, the mere addition of the fibrinolytic enzyme as in the prior art cannot efficiently decompose organic wastes and organic substances of various components, and cannot necessarily promote fermentation.

[0011] Further, the latter Patent No. 2,920,259 discloses that an immature compost mixed with anaerobic bacteria, aerobic bacteria and active rhizobia is mixed with a contaminant mainly composed of organic fibers, and a small amount of fermenting enzyme is added. The fermentation at 30 to 70 ° C. is followed by drying to obtain a compost material fermentation accelerator. The technology is
It is characterized by the fact that immature compost containing various microorganisms and contaminants mainly composed of organic fiber are mixed, fermented by adding a small amount of fermentative enzyme to ferment, and dried. This technology uses fermented organic fertilizer as a fermentation seed material, and has the same idea as a compost manufacturing method from old days, in which a completed mature fertilizer is added back to a compost element material as a compost to promote fermentation. The feature is that by using ripe organic fertilizer with useful microorganisms, the effect of actively introducing useful microorganisms into compost material, the effect of preventing the generation of hydrogen sulfide and toxic gas underground, the prevention of immobilization of phosphoric acid The effect is to exhibit the effect of growing fixed bacteria of nitrogen. Further, by drying the ripe organic fertilizer, it is convenient for storage and management.

That is, the present invention provides a seed for initiating and promoting fermentation of an organic material by microorganisms by drying and stabilizing an aged organic fertilizer and, if necessary, activating it by adding it to an organic material. It is to be. Rather than the idea of producing enzymes themselves, producing nutrients preferred by microorganisms, or collecting various microorganisms as in the present invention,
In addition, there is no idea to suppress the odor generated by the compost material except for aerobic fermentation, and there is no idea to decompose the organic material to be introduced later by enzymatic decomposition. Therefore, although the organic material can be fermented, the object of the present invention in which the compost material is fermented and decomposed in a shorter time than before can not be achieved.

[0013]

SUMMARY OF THE INVENTION The first object of the present invention is to catalyze any of organic wastes and organic substances in which various and complex components are mixed, thereby exhibiting enzyme activity. The production of large amounts of fermentation enzymes that can be performed, and the generation and inclusion of nutrients preferred by microorganisms occur in tandem, resulting in a synergistic amplification of the fermentation promoting effect of organic matter. The purpose is to develop fermentation decomposition materials.

A second object of the present invention is that the material for accelerating fermentation decomposition of organic matter mainly composed of fermentation enzymes is an acidic solution, which can reduce the odor of organic waste and the like to be subjected to fermentation decomposition. The purpose is to make it disappear instantly, and then promote the decomposition and fermentation, thereby preventing odor pollution.

A third object of the present invention is to use the material for promoting fermentation decomposition of an organic substance, whereby the organic substance expresses an enzymatic activity as a pretreatment, and a part or all of its constituents can be reduced in a short time. Decomposed state is to promote and promote the subsequent microbial fermentation decomposition action.

A fourth object is to pay attention to the property (environmental compatibility) that when a microorganism encounters an organic substance to be fermented and decomposed, it produces a large amount of an enzyme suitable for decomposing the constituents of the organic substance. Accordingly, it is an object of the present invention to provide a method for producing an adaptive fermentation decomposition promoting material having a fermentation decomposition activity of a specific organic substance to be processed in a predetermined procedure.

[0017]

The first invention to be patented is to mix mineral water and / or mineral water containing koji and mineral components with heat-treated rice bran or fu and water. A fermentation decomposition promoting material for organic matter, characterized in that it is self-digested with an enzyme of koji to form an enzyme digestion solution, mixed with the yeast and fermented to form an acidic solution containing alcohol, lactic acid bacteria and organic acids. It is a manufacturing method.

The first invention is a method for producing a basic material for promoting fermentation decomposition of organic matter. This fermentation degradation accelerating material is a liquid form produced by firstly digesting rice koji in the first stage to produce an enzyme digestion solution, and then fermenting it in a second stage by yeast to produce an acidic solution containing alcohol, lactic acid bacteria and organic acids. It is a material.

First, an enzymatic digestion solution produced by autolysis of koji will be described. Aspergillus has a long history of decomposing proteins, starches and lipids in beans and cereals.
It is known to make brewed foods such as soy sauce and sake. That is, aspergillus can produce many kinds of enzymes such as various amylase which degrades starch, various protease which degrades protein, lipase which degrades lipid, and cellulase which degrades fiber in microorganisms. Therefore, rather than administering a single enzyme, many enzymes can be used at low cost only by using koji. Garbage and organic waste that are composted and used as raw materials for organic fertilizers include starch, protein,
Since it contains many components such as fat and fiber, the use of koji enzymes is suitable for the decomposition and fermentation of raw material organic matter containing many components.

Also in the case of the present invention, koji added as a raw material is self-digested by various enzymes generated by itself, and becomes an enzyme digestion solution. The enzymatic digestion solution includes dextrin, which decomposes starch in koji by the enzyme α-amylase produced by Aspergillus, and those decomposed into glucose by β-amylase or glucoamylase. ing. In addition, proteins in koji include those that are decomposed into peptides by the enzyme proteinase, and peptides and amino acids are generated by the enzyme peptidase. These are the high-molecular-weight degrading action of enzymes such as starch and proteins, and at the same time, the decomposed products serve as nutrients for yeast, lactic acid bacteria, and acetic acid bacteria that work thereafter, and promote the growth and activation of these microorganisms. .
Furthermore, minerals, vitamins and nucleic acids in rice bran added as a raw material, and minerals in mineral water added as a raw material also serve as nutrients (growth factors) that promote the growth and activation of microorganisms, and fermentation and decomposition of organic matter. Promotes action. As described above, the enzyme digestion solution contains a large amount of glucose, dextrin, peptide, and amino acid generated by itself, and also contains a large amount of vitamins, nucleic acids, and minerals added as raw materials.

Next, as a subsequent treatment, yeast is added to the enzyme digestion solution obtained in the preceding treatment and fermented. Then, the yeast mainly decomposes glucose into alcohol and carbon dioxide gas by fermentation by the microorganism, and lactic acid bacteria mixed in the fermentation and lactic acid bacteria contained in rice bran generate lactic acid from glucose. Furthermore, other organic acids are produced by the bacteria which are similarly mixed during the fermentation. The fermented enzyme solution becomes an acidic solution having a pH of about 4.0 ± 0.5 due to the lactic acid and other organic acids thus generated. The fermentation enzyme solution of this acidic solution becomes a raw material for instantly deodorizing alkaline odors such as ammonia and amine emitted from organic waste and manure.

As described above, the materials for promoting fermentation degradation of organic substances according to the present invention include various types of enzymes such as various amylase, various proteases, lipases and cellulases produced by Aspergillus oryzae, and glucose produced by the enzymatic degradation. , Peptides, amino acids and other nutrients (growth factors), nutrients (growth factors) such as vitamins, nucleic acids, and minerals added as raw materials, and alcohol, carbon dioxide, acetic acid, lactic acid, It is a liquid material containing a large number of other organic acids and various microorganisms, such as lactic acid bacteria, acetic acid bacteria, koji molds and other fermenting bacteria, which act during fermentation decomposition.

An element which promotes the decomposition and fermentation of organic matter by a parallel double fermentation action of fermentation by various nutrients (growth factors) and lactic acid bacteria and yeast, as well as the decomposition action of various organic substances by these various enzymes. It is an accelerating material that is produced one after another, and whose elements are linked and fermented and decomposed in a short period of time without producing bad smell. It is characterized by the necessary fermentation enzymes (amylase, protease, lipase, cellulase) that can catalyze both organic wastes and organic matter containing complex and diverse components and can express enzyme activity. ), And contains a large amount of glucose and dextrin produced by enzymatic decomposition. In addition, minerals and vitamins and nucleic acids in rice bran, minerals in mineral spring water and other nutrient sources (growth) Factor).

[0024] Further, it contains alcohol decomposed by fermentation of yeast, carbon dioxide, and organic acids such as lactic acid generated by lactic acid bacteria, thereby forming an acidic solution. In addition to the rich nutrient sources preferred by microorganisms,
Since it is in an acidic state, environmental conditions that facilitate aerobic fermentation are in place. As described above, the present invention contains a large amount of enzymes, microorganisms, and nutrients, and is further in an acidic state,
The compost (organic fertilizer) that activates these components by merely adding them to the organic matter, promotes fermentation in cooperation with each other, and does not cause crop growth failure in a relatively short time is produced.

That is, the fermentation decomposition promoting material is simply mixed with organic matter such as waste, which is a diverse and complex component,
The odor of the organic substance is eliminated, and the organic substance is first decomposed by an enzyme. In addition, the microorganisms are propagated in the decomposed organic matter, and the microorganisms are further proliferated and activated by a nutrient generated by self-decomposition, so that the fermentation can be rapidly and strongly performed.

The reason why rice bran was first heat-treated is that rice bran contains many nutrients, such as vitamins, which are preferred by microorganisms, and various germs are easy to propagate. In order not to inhibit the autolysis function of the koji. Also, mineral water is added to mineral water because it contains enzyme skeletal components and mineral components that serve as growth factors for microorganisms, and by adding these nutrients, the microorganisms are activated and fermentation is facilitated. .

As described above, the present invention firstly provides that nutrients such as glucose and amino acids decomposed from starch and protein, vitamins of rice bran, lactic acid, acetic acid, cunic acid, and mineral water of mineral water decomposed from rice bran. Second, conditions such as cell walls of organic matter are partially destroyed by fermentation enzymes, and microorganisms such as aerobic bacteria, koji mold, actinomycetes, and filamentous fungi are easily fermented. Is ready,
By promoting the activity of the microorganisms, the fermentation can be completely fermented and decomposed in a shorter period of time, and an aged organic fertilizer can be produced in a shorter period of time while suppressing odor.

Next, when the target organic substance is decomposed and fermented using the fermentation decomposition promoting material according to the present invention, the odor generated by the organic substance as a raw material is instantaneously deodorized.
It is a major feature that even after entering the fermentation stage, the fermentation decomposition action is promoted while the odor is suppressed, and the fertilizer can be matured without emitting bad odor. Less than,
The deodorizing mechanism when the target organic matter is decomposed and fermented using the fermentation decomposition promoting material according to the present invention will be described.

The main components of foul odors such as livestock manure and garbage can be roughly classified into 1) nitrogen-containing compounds such as ammonia and methylamine, 2) sulfide-containing compounds such as hydrogen sulfide and methyl mercaptan, 3) acetaldehyde and propion. Aldehydes such as aldehydes; and 4) fatty acids such as butyric acid and valeric acid.

The most abundant of these odors is ammonia, which is a nitrogen-containing compound. The fermentation enzyme solution is acidified by lactic acid or the like, and weakly alkaline ammonia is adsorbed by the acidic solution and ionized to eliminate odor. Further, when fermentation is continued under aerobic conditions, nitric acid is changed to nitrate and the odor is eliminated. The amines are adsorbed by the acidic enzyme solution almost similarly and become odorless.

Hydrogen sulfide, which is a sulfide-containing compound, is first dissolved by the fermentation enzyme solution. Since the fermentation enzyme solution contains a soluble component such as alcohol, it is considered that the fermentation enzyme solution is adsorbed to the fermentation enzyme solution during stirring. Adsorbed and dissolved, almost no odor. Thereafter, under aerobic conditions, it is gradually oxidized to sulfate by sulfur bacteria.

Further, aldehydes and fatty acids are compounds having an aldehyde and a carboxyl group at the terminal of a straight chain hydrocarbon. These residues have an affinity for water and the hydrocarbon moiety has an affinity for alcohol. The fermentation enzyme solution containing these water and alcohol easily dissolves aldehydes and fatty acids. Upon dissolution, the odor is reduced or almost eliminated. After dissolution, fermentation under aerobic conditions changes to carbon dioxide and water.

As described above, the mechanism of deodorization in a short time is considered to be the cause of deodorization because the fermentation enzyme solution is an acidic solution with lactic acid and the like, and the adsorption of odor with alcohol and the like having a dissolving power. For this adsorption and solubilization,
It is necessary that the fermentation enzyme solution be sufficiently distributed to the livestock manure and garbage as raw materials and that sufficient stirring be performed. In addition, digestive juices of rice koji and yeast contain many enzymes, and it is considered that immediate reaction of these enzymes and deodorization also accelerates deodorization. In the long run, under relatively aerobic conditions, mold,
We believe that yeast, bacteria, actinomycetes, and many microorganisms will contribute to deodorization.

According to a second invention, which is to be patented, rice bran or fu and water are heat-treated at about 70 to 80 ° C., mixed with rice koji and mineral water containing mineral components and / or mineral water. 55 ~ 60 ℃ mainly by koji enzyme
The enzyme digestion solution produced by saccharification by self-digestion for 1 to 3 hours is cooled to room temperature of about 30 ° C., and yeast is mixed into the enzyme digestion solution at about 30 to 35 ° C. for 1 to 3 hours.
This is a method for producing a material for promoting fermentation and decomposition of organic matter, wherein the material is made into an acidic solution containing alcohol, lactic acid bacteria, and organic acids produced by fermentation for three days.

The second invention is a method for producing a material for accelerating fermentation decomposition of an organic substance more efficiently and more specifically than the first invention which is a basic invention. First, the present inventor decomposes organic matter containing complex and diverse components with a fermentation enzyme, or generates and contains a nutrient source preferred by microorganisms by self-digestion to promote fermentation. Second, the fermentation decomposition promoting material for organic matter mainly composed of this fermentation enzyme is an acidic solution, and the organic matter to be subjected to fermentation decomposition is used. The odors such as wastes are instantaneously eliminated, and the decomposition and fermentation are promoted to prevent odor pollution. Third, when the material for promoting fermentation and decomposition of organic matter is used. As a pretreatment, an organic substance expresses an enzyme activity as a pretreatment, and a part or all of its components are decomposed in a short time.

The third invention is an invention of an embodiment in which raw materials are numerically limited more specifically than the first invention.

This is a method for producing an adaptive fermentation decomposition material having an activity of decomposing plant organic matter, which is obtained by mixing an organic matter mainly composed of vegetable protein into a decomposition promoting material and fermenting and decomposing it.

The fifth invention is directed to the production of an adaptive fermentation decomposition promoting material exhibiting a decomposing activity particularly for plant organic substances, based on the fermentation decomposition promoting material for organic substances produced in the first to fourth inventions. Is the way. The adaptive fermentation decomposition promoting material according to the present invention is a granular, granular, or small solid material. The present invention focuses on the property that when a microorganism encounters an organic component of an object to be fermented and decomposed in earnest, a large amount of an enzyme suitable for decomposing the constituent components of the organic substance is produced, and the plant organic substance is used.

[0046]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on embodiments. The material for promoting fermentation decomposition of organic matter according to the present invention was produced as follows. The mixing ratio of the raw materials prepared for producing the fermentation decomposition promoting material is as follows.

<Raw material mixing ratio> Rice bran 60 liters Water 540 liters Rice koji 180 liters Mineral water 60 liters Yeast 1.5 liters

The production of the fermentation decomposition accelerating material according to the present invention
First, a mixture of 60 liters of rice bran and 540 liters of water is heated at 80 ° C. Next, the temperature was lowered to 60 ° C., and 180 liters of rice koji and 60 liters of mineral water containing mineral components were mixed. Then, while keeping the mixture at approximately 60 ° C., the mixture was placed for 1 to 3 hours. Self-digest. This autolysis of rice koji means that the starch in rice koji is converted to dextrin by α-amylase and degraded to glucose by β-amylase or glucoamylase, and the protein in rice koji is decomposed into peptides by proteinase. And further degraded to amino acids by peptidase. An enzymatic digestion solution containing the product obtained by enzymatic decomposition of these rice koji was prepared. Next, the enzyme digestion solution is allowed to cool to room temperature of 30 ° C. or lower, and then 1.5 liters of yeast is mixed with the enzyme digestion solution and fermented at approximately 30 to 35 ° C. for 1 to 3 days. The yeast then ferments the glucose and breaks it down into alcohol and carbon dioxide. Lactic acid bacteria contained in rice bran ferment glucose to produce lactic acid. The organic acid such as lactic acid turns the mixed solution into an acidic solution having a pH of 4 ± 0.5. This is an example of 830 liters of a basic organic matter fermentation decomposition promoting material.

Next, an experiment was conducted to produce compost using the material for accelerating the fermentation decomposition of the liquid organic substance produced as described above, and the fermentation decomposition of the organic substance produced according to the present invention was carried out. The effect of the promotion materials was confirmed. As an organic substance, 1000 kg of an organic substance raw material having a mixing ratio of pig dung 40: cow dung 60 is prepared, and 3 liters of the organic matter fermentation decomposition promoting material, 9 liters of mineral water, and 1 liter of rice bran are made substantially uniform throughout. To mix. To this is added 300 kg of aged compost to adjust the water content of the whole organic matter raw material to about 60 to 70%. The aged compost is generally 15-30% moisture
Therefore, even when the water content of the organic material (eg, sludge or garbage) is as high as 70% to 95%, the water content can be easily adjusted by mixing the returning compost.
The organic matter raw material whose water content has been adjusted in this manner is put into a fermentation tank, and a temperature of 30 to 42 ° C is added to the adjusted raw material, and fermentation is performed for 24 hours while stirring for about 15 minutes per hour. As a result, after 48 hours, the main odor almost disappeared, as shown in FIG. That is, the organic material raw material before the treatment had a rather strong odor such as ammonia, hydrogen sulfide, and methylcaptanamine, but these odors rapidly increased one hour after the organic material material according to the present invention was mixed and stirred. The odor was reduced and almost no odor was felt. In particular, the strong smell of ammonia smell was greatly reduced to 1/200 after one hour,
After 48 hours, the odor was reduced to 1/400. As a result, there has been almost no fear of complaints from neighbors as odor pollution. And the thing which completed primary fermentation is moved to a secondary fermentation tank, and when it stirs while blowing in hot air, secondary fermentation starts and 70-80 degreeC
And heats up to an aging state in about 10 days. This aged organic fertilizer can no longer germinate even if Komatsuna seeds are planted.
It became 0%, and the komatsuna grew greatly without any developmental disorders. The result of the deodorization using the fermentation decomposition promoting material is as shown in FIG.

Livestock excrement has an intense odor immediately after being put into a composting fermenter or the like, since the odor of the raw material is emitted as it is. How to deodorize this quickly is an important technical issue in composting treatment technology that emphasizes environmental protection. Among the malodors in this case, ammonia and amines that are generated in large quantities are weakly alkaline, whereas the fermentation decomposition promoting material is an acidic solution, which is adsorbed and neutralized to eliminate the odor. Also, hydrogen sulfide,
Sulfur-containing compounds such as methyl mercaptan and aldehydes such as acetaldehyde contain a solution having a dissolving power due to alcohol contained in a fermentation decomposition promoting material, so that the odor is solubilized therein and deodorized. In order to solubilize the odor of the organic material, it is necessary to sufficiently distribute the fermentation decomposition promoting material by stirring.

As shown in Table 1, when the components of the compost produced using the fermentation decomposition promoting material of the present invention were analyzed, the results are as shown in Table 1.

[0052]

[Table 1]

As described above, the fermentation decomposition material for organic matter according to the present invention has a high fertilizer effect because of its high content of nitrogen, phosphoric acid, and potassium components.

First, the basic material for promoting fermentation and decomposition of organic matter according to the present invention is manufactured. As shown in FIG. 1, it is made by mixing 60 liters of rice bran with 540 liters of water in 8
After heating at 0 ° C. and then lowering it to 60 ° C.
Mineral water containing 180 liters of rice koji and mineral water 6
0 liters, then mix these mixtures for approximately 6
The rice koji is self-digested by keeping it at 0 ° C for 1 to 3 hours to form an enzyme digestion solution containing the product obtained by enzymatic decomposition. Next, the enzyme digestion solution was allowed to cool to room temperature of 30 ° C. or lower, and yeast 1.5 g was added to the enzyme digestion solution.

The basic material for promoting fermentation and decomposition of organic matter according to the present invention exerts a catalytic action on both organic waste and organic matter in which various and complex components are mixed, and expresses enzyme activity. In addition to producing and containing a large amount of fermentation enzymes that can be produced by self-digestion, it also produces and contains nutrient sources preferred by microorganisms, and its actions such as self-digestion and self-generation of nutrients by decomposition are linked. Thus, a material for promoting fermentation decomposition of organic substances that synergistically amplifies the effect of promoting fermentation has been embodied.

Since the material for promoting fermentation decomposition of organic matter mainly composed of fermentative enzymes according to the present invention is an acidic solution containing an organic acid such as lactic acid, weakly alkaline ammonia is adsorbed on the acidic solution and ionized. The smell is gone,
The amines are adsorbed by the acidic enzyme solution almost similarly and become odorless. As a result, odors such as organic wastes to be subjected to fermentation decomposition are instantaneously eliminated, and furthermore, decomposition and fermentation are promoted, and odor pollution can be prevented.

When the material for promoting fermentation decomposition of an organic substance according to the present invention is used, the organic substance develops an enzymatic activity as a pretreatment, and a part or all of its constituents are decomposed in a short time. This helps the subsequent microbial fermentation and decomposing action, and can promote composting in a short period of time.

When a microorganism encounters an organic substance to be fermented and decomposed, the microorganism focuses on the property of producing a large amount of an enzyme suitable for decomposing the constituents of the organic substance (environmental adaptability) and focuses on a specific substance. It is another object of the present invention to provide a method for producing an adaptive fermentation decomposition promoting material having a fermentation decomposition activity of a specific organic substance to be processed in the above procedure. That is, it was possible to produce an adaptive fermentation decomposition promoting material that exhibits strong fermentation decomposition activity for each of plant organic matter, livestock organic matter, and seafood organic matter.
