Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a maturation accelerator for decomposing organic substances such as garbage to form compost.

[0002]

2. Description of the Related Art As a method of effectively utilizing garbage generated in general households and restaurants, there is a treatment method of decomposing garbage, ripening it, and composting it. As the ripening accelerator for corn, those utilizing microorganisms are provided on the market. The decomposition of garbage by this microorganism means that the microorganism grows in the garbage and the bacterium decomposes the garbage into carbon dioxide and water by the action of the microorganism. Fill the end in the ground,
Into this processing container, raw garbage is introduced from a raw garbage inlet formed at the upper end of the container, and a maturation accelerator containing microorganisms as a main component is sprayed on the raw garbage. Is being converted.

[0003]

However, in the above-mentioned garbage decomposing process, even when the processing container is hermetically closed while leaving the garbage or the maturation accelerator, pests such as flies may be removed by the processing container. Invading the inside and laying eggs there, maggots are generated in the processing container, giving the operator discomfort, causing a large amount of flies, which is unsanitary.

In order to suppress the increase in maggots, it is effective to spray insect repellents to kill the maggots. However, some components of the insect repellents include microorganisms which are the main components of the maturation promoter. Some antibacterial agents show antibacterial properties. By spraying an insect repellent having such a component, the growth of microorganisms may be inhibited, which may hinder the progress of decomposition by the microorganisms. For this reason, conventionally, when maggots were generated, the insect repellent was sprayed, but in such a method, the insect repellent had to be sprayed every time the maggots were generated separately from the maturation accelerator. There is a problem that it takes time and effort for the operator.

The amount of insect repellent to be sprayed is limited to an amount that does not hinder the progress of the decomposition of garbage by microorganisms, so that the generated maggots may not be able to be completely killed. The problem is that the occurrence of maggots increases, and the insect repellent is sprayed after the maggots are generated. Therefore, it is not possible to completely suppress the occurrence of maggots. There was also a problem of having a pleasant feeling.

The present invention has been made in view of such circumstances, and an object of the present invention is to incorporate a pest control component which does not inhibit the growth of microorganisms that decompose organic substances into a maturation accelerator to thereby provide a sanitary pest or an unpleasant pest. It is an object of the present invention to provide a ripening promoter capable of promoting the decomposition of organic matter by microorganisms while suppressing the generation of ripening.

[0007]

SUMMARY OF THE INVENTION The present invention provides an anti-microbial component which does not exhibit antibacterial activity against microorganisms which promote the decomposition of garbage and the like, and which is capable of killing pests such as maggots. It is made without paying attention to the fact that it does not hinder the progress of composting and can suppress the occurrence of pests such as maggots.The maturation accelerator of the present invention is a microorganism for decomposing organic substances such as garbage and the like. And a repellent component that does not inhibit the growth of microorganisms. As such an insect repellent component, 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether can be used.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION The maturation accelerator of the present invention comprises a maturation accelerator component mainly composed of a microorganism that decomposes organic substances such as garbage, and an insect repellent component having no antibacterial activity against the microorganism. .

[0009] Examples of the microorganism which is a main component of the maturation promoting component include bacteria such as Bacillus, for example, Ac
actinomycetes such as Tinomyces, for example, Aspergi
Aerobic or anaerobic microorganisms such as molds such as llus can be used, and such microorganisms can be used alone or in combination of several kinds. We have:
For example, a maturation promoting agent containing as a main component a total of 22 kinds of microorganisms consisting of 6 bacteria, 1 actinomycete, and 15 molds was prepared. Here, the maturation promoting component is obtained as a powder by, for example, adsorbing a culture solution of the microorganism on a mineral powder.

The insect repellent component contained in the ripening promoter must have a property that it has no antibacterial properties against the microorganisms that are the main components of the ripening promoter, as described above. Is not antibacterial,
It means that it does not inhibit the growth of microorganisms. Insect repellents having such properties and killing the pests include, for example, 2 based on experimental results of the present inventors described below.
-(4-ethoxyphenyl) -2-methylpropyl 3-
Phenoxybenzyl ether can be used.

The ripening promoter is a powdered ripening promoter component, which is an insect repellent component, 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether.
It is manufactured by blending Ter. The blending amount of the above-mentioned ingredients is not particularly limited, but it is desirable to blend about 0.01-0.1% of the ripening accelerator from the examples described later.

[0012] Such a rotting accelerator is used, for example, in an amount of about 1% based on garbage, for example, 5 g per 500 g of garbage.
Used by spraying degree. By spraying the maturation accelerator, the garbage is decomposed into carbon dioxide and water by microorganisms, which are the main components of the maturation-promoting component, and the maturation gradually progresses to compost. At this time, the insect repellent component 2- (4-ethoxyphenyl) -2-methylpropyl 3
-With phenoxybenzyl ether, even if a pest such as a fly approaches garbage or the like, the pest can be killed. Further, even if maggots are generated due to the spawning of the fly, the maggots can be killed, and as a result, the occurrence and increase of maggots can be suppressed.

In the present invention, an insect repellent component having no antibacterial properties against microorganisms having the ability to degrade organic substances has been discovered, and this insect repellent component has been added to a maturation accelerator. Can be suppressed. For this reason, since the generation and increase of maggots are suppressed by spraying the anti-maturation agent of the present invention, it is not necessary to spray a new insect repellent separately from the anti-maturation agent, and it is possible to save the trouble of spraying the insect repellent. .

Since the insect repellent component is a component which does not inhibit the growth of microorganisms, it can be added in a sufficient amount to suppress the generation of maggots, and therefore the generation of maggots is completely suppressed or the number of maggots is reduced. be able to. Further, since the insect repellent component is sprayed from the beginning together with the maturation promoting agent, the generation time of the maggot can be delayed as compared with the case where the maggot is sprayed after being generated. Furthermore, when the insect repellent is sprayed after the occurrence of maggots as in the prior art, discomfort is caused when the insect repellent is sprayed, but the maturation accelerator of the present invention may be sprayed first, and the maggot is sprayed when spraying. There is no discomfort because it has not occurred.

[0015]

EXAMPLES Next, Examples (Examples 1 and 2) were carried out to confirm whether or not the insect repellent component exhibited antimicrobial activity against microorganisms having the ability to decompose organic substances, and the compost of the maturation promoter of the present invention. An example (Example 3) performed to confirm the effect on the formation of insects and the insect repellent effect on maggots will be described.

Example 1 (1) 22 kinds of microorganisms (6 bacteria, 1 actinomycetes, 15 molds) used in the prototype maturation accelerator were inoculated one point at a time on a plate medium. 2- (4-
Approximately 0.1 g of “compo powder” (manufactured by Aron Kasei Co., Ltd.) having a trade name of “ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether as a main component was installed, and the morphology of the colonies that grew was observed. did. The cultivation temperature was 30 ° C. for normal-temperature bacteria and 15 ° C. for low-temperature bacteria, and the culture period was 7 days.

(2) 22 kinds of microorganisms (six bacteria, one actinomycete, one mold) used in the prototype maturation accelerator
5 strains) were inoculated one by one on a plate medium and cultured to expand the colony. Then, about 2 g of "compo powder" was sprayed on the colony, and the change of the colony was observed. The cultivation temperature was 30 ° C. for normal-temperature bacteria and 15 ° C. for low-temperature bacteria, and the culture period was 7 days.

As a result of these experiments, it was confirmed that the growth of the microorganism was not inhibited by “compo powder”, and thus, the main component of “compo powder” was 2
-(4-ethoxyphenyl) -2-methylpropyl 3-
It was confirmed that phenoxybenzyl ether does not prevent the growth of the microorganism, that is, it has no antibacterial activity against the microorganism.

EXAMPLE 2 19 of the microorganisms used in the prototype ripening promoter
One type of microorganism (4 bacteria, 1 actinomycetes, 14 molds) was inoculated at one point on a plate medium, and fenitrothion, carbaryl, 2- (4-ethoxyphenyl) -2-methylpropyl 3 -Phenoxybenzyl-
About 0.1 g of an insect repellent (trade name "King Wallaji insect-killing dust") containing ter as a main component was placed thereon, and the colonies proliferated.
Was observed, and whether or not the growth of the microorganism was inhibited by the insect repellent was confirmed by measuring the inhibition diameter (distance between colony and insect repellent). The culture temperature is 30 ° C for normal temperature bacteria and 15 ° C for psychrophilic bacteria, and the culture period is 7
Days. Table 1 shows the results.

[0020]

[Table 1] This experiment shows that the longer the diameter of inhibition, the greater the inhibitory effect of the insect repellent on the growth of microorganisms, that is, the greater the antibacterial property of the insect repellent against microorganisms. From Table 1, it was confirmed that the growth of bacteria was not inhibited by the insect repellent, but the inhibition diameter was measured for actinomycetes and 10 strains of mold, and sporulation was also observed for the remaining 4 strains of mold. Since inhibition was observed, it was confirmed that the insect repellent inhibited the growth of most of the microorganisms. Therefore, the main components of this insect repellent, fenitrothion, carbaryl, 2-
It was confirmed that the combination of (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether has antibacterial activity against most of the microorganisms.

Example 3 A transparent container having a capacity of 2 liters with a drain hole formed at the bottom was installed outdoors, and 500 g of garbage was placed in the container.
On the garbage, a maturation accelerator was sprayed on the first and fourth days in an amount of 5 g each to observe the occurrence of maggots and the degree of decomposition of the garbage. The maturation accelerator to be sprayed is obtained by mixing 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether as an insect repellent with the maturation accelerator containing the above 22 kinds of microorganisms. Is 0.01
%, 0.05%, and 0.1%. In addition, as a comparative experiment, the same test was carried out for the case where the insect repellent component was not added and the case where the anti-ripening agent was not sprayed.

For the occurrence of maggots, the number of occurrences per day was examined by visual observation. Table 2 shows the results. In the table, "none" indicates that no maggots were generated, "small" indicates that the number of maggots was less than 10, and "many" indicates that the number of maggots was 10 or more. I have.

[0023]

[Table 2] As a result, it was recognized that maggots were generated on the fourth day in all the treatment groups. However, when the ripening accelerator was additionally sprayed on the fourth day, the mulching accelerator containing the insect repellent component was sprayed. Although no increase in the number of maggots was observed, the increase in the number of maggots was observed in the treatment group in which the maturation promoter containing no insect repellent component was sprayed and in the treatment group in which the maturation accelerator was not sprayed. This confirmed that the use of a ripening accelerator containing 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether as an insect repellent component could suppress an increase in maggots. In addition, no difference was found to the extent that the number of maggots increased due to the difference in the amount of the insect repellent component.

The degree of decomposition of the garbage was confirmed by measuring the weight. That is, the fact that the weight became 80% of the original weight of garbage means that 20% of the garbage
Was decomposed into carbon dioxide and water, indicating that the lower the weight, the more the degree of decomposition was progressing. The result is shown in FIG. ○ in the figure
Is a case where 0.01% is blended with 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether, □ is a case where 0.05% is blended, Δ is a case where 0.1% is blended, Indicates the case where the insect repellent component was not added, and ■ indicates the case where the ripening promoter was not sprayed.

As a result, the weight of the garbage is smaller in the treatment section in which the maturation promoter is sprayed than in the treatment section in which the maturation accelerator is not sprayed, whereby the decomposition of the garbage is promoted by spraying the maturation accelerator. It was confirmed that. Also, 2- (4
-Ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether showed no significant difference in the degree of decomposition depending on the presence or absence of the compound. Thereby, 2- (4
-Ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether was found not to hinder the progress of the decomposition of garbage and promote the maturation of the garbage. In addition, in FIG. 3, when the said insect repellent component was mix | blended 0.01% and the case where 0.1% was mix | blended,
This indicates that the weight of the garbage is greatly reduced as compared with the case where the content of the garbage is 0.05%.

According to the results of Examples 1 to 3, 2- (4
-Ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether does not hinder the growth of microorganisms, which are the main component of the ripening promoting component, and has the property of having no antibacterial properties and the property of inhibiting the occurrence of maggots. It was confirmed to be an insect repellent component, and this 2- (4-ethoxyphenyl)
It has been confirmed that a ripening accelerator containing -2-methylpropyl 3-phenoxybenzyl ether as an insect repellent component can promote the decomposition of garbage while suppressing the generation of maggot, and can promote ripening. In addition, no difference was observed in the number of maggots and the degree of decomposition of garbage depending on the amount of 2- (4-ethoxyphenyl) -2-methylpropyl 3-phenoxybenzyl ether. It has been found that the amount is not particularly limited, but from the viewpoint of cost, it is desirable to set the amount of the ripening accelerator to about 0.01 to 0.1%.

In the above, the insect repellent component contained in the maturation accelerator of the present invention can kill insects such as sanitary pests other than flies and maggots, or unpleasant pests such as black ants, spiders, spiders, and worms. it can.

[0028]

According to the maturation accelerator of the present invention, an insect repellent component that does not inhibit the growth of microorganisms that decompose organic substances is added to the maturation accelerator, thereby suppressing the occurrence of sanitary pests or unpleasant pests. , The decomposition of organic matter can be advanced.
