일반적으로 산업화의 계속적인 진행으로 생활 여건 및 환경이 좋아지면서 산업체에서 나오는 난분해성 폐수뿐만 아니라 고농도의 유기물을 함유한 축산업 폐기물이 환경문제로 크게 대두되고 있으나, 이러한 축산폐기물은 지속적인 양적 증가뿐만 아니라 농축된 유기물 및 화학물질을 이용한 처리시 상당한 어려움을 더하고 있다. 따라서 축산 폐기물의 생물학적 처리를 통한 고기능을 갖는 생물 비료의 개발은 유기질비료자원의 활용으로 자원의 재활용과 환경오염의 경감을 가져온다. 특히 토양의 비옥도가 낮은 현실에서 가축분뇨의 유기질 비료로의 전환은 그 의의가 크다.In general, as industrial conditions continue to improve, living conditions and the environment improve, not only hardly degradable wastewater from industrial fields but also livestock wastes containing high concentrations of organic matter are emerging as environmental issues. Significant difficulties are added to the treatment with organics and chemicals. Therefore, the development of high-performance biological fertilizers through biological treatment of livestock waste brings about the recycling of resources and the reduction of environmental pollution through the use of organic fertilizer resources. In particular, the conversion of livestock manure to organic fertilizer is significant in the low soil fertility.

유기물질의 퇴비화는 미생물 활동결과 안정화된 퇴비로 전환시키는 과정으로서 여러 요인들이 작용하나 궁극적으로는 미생물의 활성을 촉진시키는 것이라 할 수 있다. 따라서 미생물의 활성을 증가시키기 위해 유용한 미생물 제제의 활용에 대한 검토가 많이 이루어져 왔는데, 락토바실러스 플란타름(Lactobacillus plantarum), 바실러스 서브틸리스(Bacillus subtlis), 페니바실러스 마르세란스(Paenibacillus marcerans) 등을 첨가한 퇴비화 효과에 대한 보고가 있다. 또한 작물의 재배에 있어서 방제가 까다로운 토양전염성 식물병원균들에 있어서 현재까지 뚜렷한 방제 대책이 없어 해마다 작물의 연작시 그 피해가 증가하고 있다.Composting of organic material is a process of converting the result of microbial activity into stabilized compost, but many factors work, but ultimately it promotes the activity of microorganisms. Therefore, many studies have been made on the use of useful microbial agents to increase the activity of microorganisms. There are reports of added composting effects. In addition, there is no clear control measures to soil infectious phytopathogens that are difficult to control in the cultivation of crops.

따라서, 이러한 문제점을 해결하기 위해 무공해 방제기술인 길항 미생물을 이용한 농작물의 병피해 방지기술의 개발이 필요한 실정이다. 이를 위한 방안으로 축산폐기물의 비료화와 식물병을 방제할 수 있는 유용미생물의 선발과 적용은 중요한 과제라 할 수 있다.Therefore, in order to solve this problem, it is necessary to develop a disease prevention technology of crops using antagonistic microorganisms, which are pollution control technologies. For this purpose, the selection and application of useful microorganisms that can fertilize livestock waste and control plant diseases are important tasks.

미부숙된 퇴비를 토양에 사용할 경우 병해충의 먹이를 제공하여 병해충의 피해를 받을 우려가 높고 시설하우스에서는 토양중 발효가 일어나 암모니아, 질산등의 가스발생으로 작물이 피해를 입게 된다. If uncomposed compost is used in the soil, it is highly likely to be damaged by providing pest food. In the facility house, the fermentation occurs in the soil, which causes damage to crops due to gas generation such as ammonia and nitric acid.

따라서 유기성 폐자원의 농업적 재활용과 고품질의 퇴비생산을 위하여 악취경감 및 부숙촉진 미생물에 대한 연구가 절실하다고 할 수 있다. 섬유질을 분해하는 바실러스(Bacillus)속 미생물중에는 글루코스(glucose)를 포함한 다양한 당을 이용하여 산을 생성하고, 특히 질소가 있는 경우 산소가 부족하여도 최소 일주일 정도는 생육이 가능한 미생물로 토양, 마른풀, 먼지 등 자연계에 널리 분포하는 그람 양성(Gram positive)의 간균으로 길이는 2-3㎛로서 호기성이며, 내생포자(endospore)를 형성하는 미생물이 많이 존재한다.Therefore, it is urgent to study odor-reducing and home-promoting microorganisms for agricultural recycling of organic waste resources and producing high quality compost. Among microorganisms of the genus Bacillus, which degrades fiber, acid is produced by using various sugars including glucose, and especially in the case of nitrogen, it is a microorganism capable of growing for at least one week even when oxygen is insufficient. Gram positive bacillus widely distributed in nature such as, dust, etc., 2-3㎛ in length, aerobic, there are many microorganisms forming endospores.

퇴비의 탄소원인 톱밥 등은 셀루로스(cellulose), 헤미셀루로스(hemicellulose)를 비롯하여 리그니(lignin) 및 펙틴(pectin)과 같은 분해되기 어려운 물질로 되어 있으나, 바실러스속 미생물중 일부는 체외분비효소인 씨엠씨아제(CMCase), 자일라나제(xylanase)와 락타제(lactase)등을 분비하여 난분해성 물질을 분해하고 이를 탄소원으로 이용한다. 이처럼 바실러스속 균주는 생육이 양호하고, 다양한 특수성을 가진다는 점에서 보다 강력하고 안정성이 우수한 효소를 생산하는 균주로 유기성 폐자원의 재활용등 농업환경개선 측면에서 활용될 수 있도록 다양한 측면의 연구가 필요하다고 판단된다.Sawdust, a carbon source of compost, is composed of cellulose, hemicellulose, and other difficult-to-decompose substances such as lignin and pectin, but some of the Bacillus microorganisms are secreted in vitro. Phosphorus CMCase, xylanase and lactase are secreted to decompose refractory materials and use them as carbon sources. As such, Bacillus strain is a strain that produces more powerful and stable enzyme in terms of good growth and various specificities, and requires various aspects of research so that it can be utilized in terms of improving the agricultural environment such as recycling of organic waste resources. It is judged that

특히 유기성 폐자원인 축산 폐기물의 안정적인 부숙 퇴비화와 길항효과를 갖게 하는 데는 안정화된 미생물의 적용에 있어서 적당한 담체를 필요로 한다. 미생물이 쉽게 부착 성장될 수 있는 담체의 조건으로 미생물이 충분히 부착될 수 있도록 다공성과 넓은 비표면적을 가져야 한다. 또한 미생물의 안정적인 활성을 위해서는 무엇보다도 미생물에 적합한 영양원이 있어야 한다.In particular, in order to have stable home composting and antagonistic effects of livestock waste, which is an organic waste resource, a suitable carrier is required for the application of stabilized microorganisms. The microorganisms should have a porosity and a large specific surface area so that the microorganisms can be sufficiently attached under conditions of a carrier which can be easily attached and grown. In addition, for the stable activity of microorganisms, a nutrient source suitable for microorganisms must be above all.

본 발명은 식물 병원성 진균에 대한 항진균 활성을 가지며 축분을 포함하는 난분해성 유기물의 분해 촉진 기능이 있는 브레비바실러스속 미생물 균주를 이용하여 환경친화적인 식물병 방제제 및 항진균 활성에 더하여 축산폐기물 등의 유기물 분해촉진제 등의 다기능적 미생물 제제를 제공함에 그 목적이 있다.The present invention uses the Brevibacillus microorganism strain having antifungal activity against plant pathogenic fungi and has a function of promoting degradation of hardly decomposable organic substances including sperm, in addition to environmentally friendly plant disease control agents and antifungal activity, such as livestock waste. An object of the present invention is to provide a multifunctional microbial agent such as an organic decomposition promoter.

실시예 3 : 본 발명 미생물 제제(C 타입, G 타입)의 퇴비부숙 효과Example 3: composting effect of the present microbial preparations (type C, G type)

본 발명은 퇴비화를 촉진시키는 미생물을 제제화하여 퇴비화 과정중에 일어나는 부숙 유기물의 완숙한 과정에 대한 적합성을 규명하고, 각종 유기 및 무기성분의 구성비율을 조사하여 물리화학적 변화를 살펴보았고, 이와 동시에 부숙화 과정중에 발생되는 암모니아가스, 휘발성 유기산성분 등 악취성분의 발생특성에 대하여 상대 비교 분석하여 평가함으로써 악취발생량이 적은 고품질의 퇴비를 생산할 수 있는 미생물 제제를 완성하였다.The present invention is to formulate the microorganisms to promote the composting to determine the suitability for the mature process of the maturation organic matter occurring during the composting process, and to investigate the physicochemical changes by examining the composition ratio of various organic and inorganic components, and at the same time Relative comparative analysis of the development characteristics of malodorous components such as ammonia gas and volatile organic acid components generated during the process was carried out to complete a microbial preparation capable of producing high-quality compost with a low amount of malodors.

처리구별 미생물 및 담체처리양은 처리구별 무게중량에 대비하여 처리하였으며, 미생물은 1%, 미생물 제제는 무게중량대비 4.5%로 처리하였다. 각각의 처리내용은 대조구(C), 미생물 단독 처리구(M), C처리구(C+M), G처리구(G+M)등 4개의 처리구를 두고 실험을 실시하였다.The amount of microorganisms and carriers by treatment group was treated relative to the weight weight of each treatment group, and 1% of microorganisms and 4.5% of microbial formulations were treated. Each treatment was experimented with four treatments, control (C), microbial alone treatment (M), C treatment (C + M), G treatment (G + M).

퇴비화 과정중 각종 유기 및 무기성분 등의 물리화학적 변화를 분석한 결과는 다음과 같다.The results of analyzing the physicochemical changes of various organic and inorganic components during the composting process are as follows.

1. 퇴비화의 반응기간 동안 pH 변화는 발효초기엔 별 영향이 없었으며, 기질의 분해로 인한 암모니아 등의 영향에 의해 상승 후 기간이 지남에 따라 감소하였으며 pH가 8.5~9.0 정도를 유지하였다.1. During the composting period, the pH change was not affected in the early stage of fermentation. The pH was decreased over the period after the rise due to the ammonia effect of substrate decomposition.

2. 퇴비화 과정중 온도의 변화는 모든 처리구에서 실험 개시 후 2~3일까지 온도의 급격한 상승으로 60℃정도까지 도달하였으며, 그 이후에는 감소하여 25일에는 37~39℃까지 감소하였다.2. The temperature change during the composting process reached up to 60 ℃ due to the rapid increase in temperature from 2 to 3 days after the start of the experiment, and then decreased to 37 ~ 39 ℃ on the 25th.

3. 총탄소의 함량은 다소 감소하는 현상을 보였으나, 각 처리구마다 탄소의 차이는 온도변화와 유사한 양상을 보였다.3. The total carbon content showed a slight decrease, but the difference of carbon in each treatment was similar to the temperature change.

4. 전질소는 천연 C처리구와 G처리구는 퇴비화 25일 이후에 1.71~1.77%로 타 처리구보다 높게 나타났다.4. The total nitrogen of natural C and G treatments was 1.71 ~ 1.77% higher than other treatments after 25 days of composting.

5. C/N율은 부숙이 진행됨에 따라 퇴비화 초기에 약간 증가하다가 감소하여 25일쯤 C/N율이 21.4~30.0으로 감소하였다. C처리구와 G처리구의 최종 C/N율이 대조구와 미생물 단독 처리구의 최종 C/N율보다 낮게 나타났다. 이는 탄소함량이 감소와 질소함량의 증가가 다른 대조구와 미생물 단독 처리구보다 크게 나타났기 때문인 것으로 보인다.5. The C / N rate increased slightly during the composting period and then decreased as the maturity progressed. Then, the C / N rate decreased from 21.4 to 30.0 at 25 days. Final C / N rates of C and G treatments were lower than those of control and microbial treatments. This may be because the decrease in carbon content and the increase in nitrogen content were greater than those of other control and microbial treatment alone.

6. 퇴비화 과정중 모든 처리구의 인산함량 변화추이가 전반적으로 증가하는 경향을 나타냈다.6. In the composting process, there was a general trend of increasing phosphate content of all treatments.

7. 가리의 성분함량 변화는 퇴비화가 진행될수록 약간 증가하는 경향을 보였다.7. Changes in the composition of the girly tended to increase slightly as composting progressed.

8. N03--N은 96~106mg/kg정도이었으나 퇴비화가 진행될수록 계속적으로 증가하였고 C처리구 G처리구가 다른 처리구보다 질산태질소의 함량이 높았으며, NH4+ -N 함량은 퇴비화가 진행될수록 계속적으로 감소하는 경향을 보였다.8. N03--N was 96 ~ 106mg / kg, but it increased continuously as composting progressed. The treatment of G treatment C had higher nitrogen nitrogen than other treatments, and NH4 + -N content continued to increase as composting progressed. It tended to decrease.

9. 퇴비화 주발효 기간 후 완료단계에서 퇴비의 분석결과 비료공정 규격의 중금속의 함량 모두 농림부 고시 제 2002-7호의 부산물비료 규격이하로 검출되었다.9. Composting As a result of the compost analysis at the completion stage after the main fermentation period, the contents of heavy metals in the fertilizer process standard were found to be less than the by-product fertilizer standard of Notice No. 2002-7.

돈분의 퇴비화 과정중 악취물질로서 중요한 공정제어 인자로 이용되는 염기성가스인 암모니아 가스(Ammonia gas)와 강산성가스인 유기산(Volitie organicacid)의 발생 특성에 대하여 상대비교 분석결과는 다음과 같다.The comparative results of the characteristics of ammonia gas, a basic gas used as an odorous substance during the composting process of swine manure, and organic acid, a strong acid gas, are as follows.

1. 퇴비화 2일후부터 암모니아가스의 발생이 급격히 증가후 이후 감소하는 경향을 보였으며, C와 G처리구에서 암모니아 가스의 발생 농도가 대조구 및 미생물 단독처리구와 비교하여 최고 3배이상 크게 감소한 결과를 보였다.1. After 2 days of composting, ammonia gas was rapidly increased and then decreased, and ammonia gas concentration was decreased up to 3 times in C and G treatments compared to control and microbial treatments. .

2. 퇴비화 과정중 휘발성 유기산 성분인 부틸릭 산(butyric acid), 이소-부틸릭 발레릭 산(iso-butyric valeric acid), 이소-발레릭 산(iso-valeric acid), 프로피오닉 산(propionic acid), 아세틱 산(acetic acid)의 정량적 분석을 통하여 부숙화 정도를 평가한 결과 프로피오닉산(propionic acid)이 퇴비화 과정중 발생한 휘발성 유기산 중에 서 가장 많은 함량이 검출되었고, 전체적으로 대구조>미생물 단독 처리구>C처리구>G처리구 순으로 퇴비화 과정중 휘발성 유기산의 감소 효율이 낮은 것으로 나타났다.2. Butyric acid, iso-butyric valeric acid, iso-valeric acid, propionic acid ), Quantitative analysis of acetic acid showed that the highest content of propionic acid was found in volatile organic acids generated during composting process. In the order of treatment> C treatment> G treatment, the reduction efficiency of volatile organic acids during composting was low.
