There is a trend of increasing by about 3% (Ministry of Environment, 2014). Food waste is causing enormous economic loss. It not only causes 800 billion won in treatment costs every year, 20 trillion won in economic loss (food resource value) per year, but also greenhouse gas emissions (8.85 million tons of CO2e per year), odor, and food. It is causing major environmental pollution such as water pollution due to wastewater (5.8% of the weight of food waste).

Due to shortage, social/environmental problems, the economic burden of each emission source due to the implementation of the volume-rate system, and the necessity for the convenience of treatment methods,
있는 다양한 기술 개발 및 그 기술의 실생활 적용에 대한 수요가 점점 높아져 가고 있는 실정이다.There is a growing demand for the development of various technologies and the application of the technologies to real life.
이에 다양한 업체에서 가정용 음폐물 처리기를 개발하여 출시하고 있으며, 크게 열풍건조식, 분쇄건조식, 냉동보관방식, 가정용 음식물분쇄기 (디스포저) 방식, 미생물을 이용한 처리방식으로 분류된다. 그러나 미생물을 이용한 처리방식을 제외한 타 처리기술은 그 처리산물을 수거하여 2차 처리나 매립을 해야 하기 때문에 정부의 자원순환형 폐기물관리정책에 부응하지 못한다는 문제점을 갖는다. 따라서 음폐물 처리의 최우선 순위로 미생물을 이용한 처리방식에 의한 음폐물의 분해 또는 퇴비화하는 방안이 각광을 받고 있다.Accordingly, various companies have developed and released household waste treatment machines, and they are largely classified into hot air drying type, pulverizing drying type, freezing storage method, household food shredder (disposer) method, and treatment method using microorganisms. However, other treatment technologies, except for the treatment method using microorganisms, have a problem in that they cannot meet the government's resource circulation type waste management policy because the treated products must be collected and subjected to secondary treatment or landfill. Therefore, a method of decomposing or composting waste by a treatment method using microorganisms is in the spotlight as a top priority for waste treatment.
현재 국내에서 음식물 쓰레기와 같은 유기성 폐기물의 처리를 위해 이용되는 미생물로는 방선균류(Antinomycetes), 슈도모나스류(Pseudomonas), 페니실리움(Penicillium), 리조푸스(Rhizopus), 피치아(Pichia) 등이 있으나, 이들 미생물의 경우 물질 분해 능력이 우수하지 않아 처리 효율이 감소하고 악취가 발생될 수 있다는 한계점이 여전히 존재하는 실정이다. 또한, 미생물 각각의 단점을 상호보완하기 위한 하나의 방안으로 다양한 미생물을 포함하는 혼합 미생물 사용하는 방법이 제안되고 있으나, 이는 각 미생물이 배양되는 조건, 예를 들면 pH 및 온도 등이 서로 상이하기 때문에 미생물이 갖는 물질 분해 능력이 충분히 발휘될 수 없다는 한계점이 존재한다. 이런 한계점 극복을 위해, 단일 미생물을 사용한 경우에도 유기물 분해 효율이 충분히 발휘될 수 있는 새로운 균주의 활용이 필요한 실정이다. Microorganisms currently used for the treatment of organic waste such as food waste in Korea include Actinomycetes, Pseudomonas, Penicillium, Rhizopus, and Pichia. However, in the case of these microorganisms, the material decomposition ability is not excellent, so there is still a limit that treatment efficiency is reduced and odors may be generated. In addition, a method of using mixed microorganisms including various microorganisms has been proposed as a method to complement the disadvantages of each microorganism, but this is because the conditions under which each microorganism is cultured, for example, pH and temperature, are different from each other. There is a limit in that the ability of microorganisms to decompose substances cannot be sufficiently exhibited. In order to overcome this limitation, even when a single microorganism is used, it is necessary to utilize a new strain in which the decomposition efficiency of organic matter can be sufficiently exhibited.

50 ℃ 이상에서도 활성을 잃지 않는 균주를 아래와 같은 과정을 통해 선별하였다. 구체적으로, 경상남도 일대의 일반토양, 부엽토 및 퇴비 등에서 채취한 각종 균원 시료 1 g을 10 ml의 0.85 % NaCl 용액에 현탁하였다. 그런 다음, 상기 현탁액을 10배, 100배 및 1000배로 희석하여 영양배지(소 추출물(Beef extract) 3%, 효모 추출물(yeast extract) 5%, 아가(Agar) 1.8%, pH 7.0)가 포함된 플레이트에 도말하고, 50 ℃에서 24시간동안 배양하였다. 그런 다음, 상기 플레이트에 생성된 콜로니의 형태를 관찰한 뒤, 육안으로 보았을 때 형태가 서로 다른 콜로니를 구분하여 최종적으로 5종의 균주(이하, 'A-3', 'B-2', 'B-9', 'C-3', 'C-11'라고 함)를 선별하였다.Strains that do not lose their activity even at 50° C. or higher were selected through the following procedure. Specifically, 1 g of various fungal sources samples collected from common soil, humus, and compost around Gyeongsangnam-do were suspended in 10 ml of 0.85% NaCl solution. Then, the suspension was diluted 10-fold, 100-fold, and 1000-fold to contain a nutrient medium (beef extract 3%, yeast extract 5%, agar 1.8%, pH 7.0). Plates were plated and incubated at 50 °C for 24 hours. Then, after observing the shape of the colonies generated on the plate, colonies having different shapes when viewed with the naked eye are distinguished and finally 5 strains (hereinafter, 'A-3', 'B-2', ' B-9', 'C-3', and 'C-11') were selected.

상기 균주의 성장을 확인하기 위해, 상기 실시예 1의 균주를 영양액(nutrient broth)이 포함되어 있는 플레이트에 도말한 뒤, 50 ℃에서 12시간 배양하고, 콜로니 생성 정도에 따른 성장 속도를 확인하여 그 결과를 하기 표 1에 나타내었다. 또한, 영양 평판배지가 포함되어 있는 플레이트에 상기 실시예 1에서 선별된 균주를 접종하고 50 ℃에서 밤새도록 배양하였다. 그런 다음, 상기 배양된 균주가 존재하는 플레이트에 아이오딘(iodine)을 처리하고 투명환(clear zone)의 생성여부를 확인하여, 그 결과를 하기 표 1에 나타내었다. 여기서, 상기 영양 평판배지에는 아밀라아제의 경우 1 % 가용성 녹말(soluble starch), 프로테아제의 경우 1 %스킴 밀크(skim milk), 리파아제의 경우 1 % 트리부티린(tributyrin)가 첨가되도록 하였다.In order to confirm the growth of the strain, the strain of Example 1 was smeared on a plate containing a nutrient broth, incubated at 50 ° C. for 12 hours, and the growth rate according to the degree of colony formation was confirmed. The results are shown in Table 1 below. In addition, the strain selected in Example 1 was inoculated on a plate containing a nutrient plate medium and cultured overnight at 50 °C. Then, iodine was treated on the plate in which the cultured strain is present, and the generation of a clear zone was checked, and the results are shown in Table 1 below. Here, 1% soluble starch in the case of amylase, 1% skim milk in the case of protease, and 1% tributyrin in the case of lipase were added to the nutritional plate medium.

However, in the case of enzyme activity, it was confirmed that only A-3 among the five strains had all of the activities of amylase, protease and lipase enzymes. From the above results, it can be seen that in the case of A-3, a novel strain according to the present invention, not only the growth rate is very good at a high temperature of 50 °C, but also has all of the enzyme activities capable of decomposing carbohydrates, proteins and fats. and, accordingly, it can be seen that the efficiency of A-3 can be very high when the organic waste is applied to decomposition.

상기 [표 5]를 참조하는 경우, 오미자 추출물을 단독으로 사용하는 경우 악취를 제거하는 효과가 빠르게 나타났다. 또한 오미자 추출물과 다른 식물 추출물을 혼합하는 경우 M5 내지 M8의 범위에 의하는 경우 각 식물 추출물의 혼합에 따른 상승효과로서 유기성 폐기물의 분해효과 및 악취제거효과가 높아진다는 사실을 확인할 수 있다.Referring to [Table 5], when the Schisandra extract was used alone, the effect of removing the odor was quickly shown. In addition, when the Schisandra extract and other plant extracts are mixed, according to the range of M5 to M8, it can be confirmed that the decomposition effect of organic waste and the odor removal effect are increased as a synergistic effect according to the mixing of each plant extract.
따라서 상기 미생물에 제제에 대하여 일정한 범위의 식물 추출물을 혼합하여 식물 혼합 제제로 혼합하여 사용하는 경우 미생물의 분해활성을 높일 수 있다는 점을 알 수 있다.Therefore, it can be seen that the decomposition activity of microorganisms can be increased when the microorganisms are mixed with a plant extract of a certain range with respect to the preparation and used as a plant mixture preparation.
