Description
본 발명은 느타리버섯 재배 시 사용되는 배지의 발효에 유용한 미생물 제재의 제조방법에 관한 것으로서, 좀 더 상세하게는 현재 행하여지고 있는 자연퇴적발효과정 중에 문제가 되고 있는 유해성 곰팡이 및 혐기성세균에 의한 오염을 방지하고 버섯균사의 증식촉진 및 자실체의 수량증대를 목적으로 효소분해활성 및 느타리버섯 증식촉진효과가 우수한 미생물의 조합으로 고초균(Bacillussp.), 효모(Saccharomycessp.), 방선균(Streptomycessp.), 광합성세균(Photosynthetic bacteria) 및 고온성방선균(Thermoactinomyces) 등 5종의 미생물을 각각의 증식에 유리한 배양조건, 배지조성으로 준비한 액체배지에서 3∼6일간 배양한 후, 팽연왕겨, wood chip 등의 다공성 식물소재에 균체를 담지시겨 혼합, 건조한 느타리버섯 배지발효용 미생물제재의 제조방법에 관한 것이다.The present invention relates to a method for producing a microbial agent useful for fermentation of a medium used for cultivating oyster mushrooms, and more particularly, to prevent contamination by harmful fungi and anaerobic bacteria, which are a problem in the present natural sedimentation effect tablets. Bacillus sp., Saccharomyces sp., Streptomyces sp. Are a combination of microorganisms with excellent enzyme degrading activity and oyster mushroom growth promoting effect for the purpose of preventing and promoting the growth of mushroom mycelia and increasing the yield of fruiting bodies. , photosynthetic bacteria (photosynthetic bacteria) and thermophilic actinomycetes (Thermoactinomyces) including five species of microorganisms favorable culture conditions for each of the proliferation, 3-6 days in liquid medium prepared with the medium composition and incubated, paengyeon rice husk, wood chip, etc. The present invention relates to a method for preparing a microbial material for fermenting mixed and dried oyster mushroom medium by loading microbial cells in a porous plant material.
국내 느타리버섯의 재배농가호수는 1999년 현재 1만 여호가 넘으며 전체 버섯생산량 중 70% 이상을 차지하는 주요작물이다. 배지원료로는 볏짚, 폐솜등 섬유소함유 재료가 사용되고 있으며, 수분함량의 균일화, 연화에 의한 물리화학성의 개선 및 방선균 등 길항성 미생물의 증식에 의한 오염균의 증식억제를 목적으로 10여일간 자연퇴적발효를 실시하고 있다. 느타리버섯배지의 제조는 작물에 대한 우량토양의 역할과 같이 느타리버섯 재배에 가장 큰 영향을 주게되므로 이 발효과정의 적합 여부에 따라 버섯재배의 성공, 실패가 좌우되고 있다.The number of cultivated farm lakes in Korea is more than 10,000 as of 1999, and it is a major crop that accounts for more than 70% of the total mushroom production. Fiber medium-containing materials such as rice straw and waste cotton are used as media raw materials, and they are naturally deposited for 10 days for the purpose of equalizing water content, improving physicochemical properties by softening, and suppressing the growth of contaminating bacteria by proliferation of antagonistic microorganisms such as actinomycetes. Fermentation is carried out. The production of Pleurotus eryngii medium has the greatest effect on cultivation of Pleurotus erythritis, such as the role of good soil for crops, and the success or failure of mushroom cultivation depends on the suitability of this fermentation process.
퇴적발효의 원리는 볏짚, 폐솜 등에 함유된 탄수화물, 당류 및 단백질 등 오염미생물에 의해 쉽게 대사 될 수 있는 화합물을 고갈시키고 고온호기성 발효를 통해 방선균증식에 의한 오염미생물에 대한 길항효과를 증대시켜 느타리버섯균사가 우점적으로 증식 가능한 lignocellulose를 조성해 주는 것이다.The principle of sedimentation fermentation is the depletion of compounds that can be easily metabolized by contaminating microorganisms such as carbohydrates, sugars and proteins contained in rice straw, waste cotton, etc. Mycelium forms a lignocellulose that can proliferate predominantly.
그러나 현재 느타리재배시 사용되는 퇴적발효의 방법을 수작업 또는 경운기, 트랙터 등을 이용하며 물을 가하여 6ton정도의 퇴적더미를 쌓고 10여 일간 자연퇴적발효를 실시함으로서 수분조정이 어렵고, 혼합, 교반의 미흡으로 불완전발효에 의한 오염발생이 심각한 실정으로 배양실패율이 30∼50% 정도에 달해 느타리재배 농가의 수익성 악화는 물론 특용작물로서의 매력을 상실케 하는 주원인이 되고 있다.However, the sediment fermentation method currently used in cultivation is carried out by hand or tiller, tractor, etc. by adding water to accumulate piles of about 6 tons and performing natural sediment fermentation for 10 days. As a result of serious fermentation due to incomplete fermentation, the cultivation failure rate is about 30-50%, which is the main cause of deterioration of profitability of cultivated farmers and loss of special crops.
자연퇴적발효는 백화현상(white lime-like coating)을 지표로 고온호기성발효의 진행여부를 판단하고 있으나 다양한 미생물상(microflora) 및 미생물천이 등에 대한 제어방법이 없어 발효과정 중에 작용하는 유용미생물의 작용에 관한 구체적인 사실은 전혀 알려져 있지 않다. 또한 작업의 용이성으로 폐솜을 선호하여 원료의 90%이상을 수입하고 있는 실정으로 금후 가격의 상승, 조달문제 등이 발생할 소지가 많아 국내의 유휴농산부산물인 톱밥, 볏짚, 주박, 팽연왕겨, 미강 등으로의 대체가 요구되고 있다.Natural sedimentation fermentation is based on white lime-like coating to determine whether high-temperature aerobic fermentation is in progress, but there is no control method for various microflora and microbial transitions. The specific facts about it are not known at all. In addition, they prefer to use waste cotton for ease of operation, and import more than 90% of raw materials.Therefore, there is a high possibility of future price increase and procurement problems.Therefore, domestic idle agricultural by-products such as sawdust, rice straw, sake lees, rice husk, rice bran, etc. Replacement is required.
이런한 자연퇴적발효과정 중의 문제점들을 해결하기 위하여 본 발명자들은 발효과정 중에 유용한 작용을 하며, 균사증식촉진 및 자실체 수량증대를 꾀할 수 있는 미생물들을 연구해온 결과 탄수화물, 단백질 및 섬유소의 분해효소를 분비하고 vitamine, 아미노산 등의 버섯증식촉진 물질을 제공하는 미생물을 분리하였고, 이들의 효과적인 조합을 통해 느타리버섯 배지의 발효 및 버섯증식촉진 목적을 달성할 수 있는 새로운 실험결과를 얻을 수 있었다. 따라서 본 발명의 목적은 느타리버섯배지의 오염방지와 수량증대에 적합한 미생물제재의 제조방법을 제공하는데 있다.In order to solve the problems of spontaneous sedimentation effect, the present inventors have a useful function during the fermentation process, and as a result of studying microorganisms that can promote mycelial growth and increase the yield of fruiting bodies, secreting carbohydrate, protein and fibrinolytic enzymes Microorganisms that provide mushroom growth promoting substances, such as vitamins and amino acids, were isolated and their effective combinations yielded new experimental results to achieve fermentation and mushroom growth promotion objectives of oyster mushroom media. Accordingly, an object of the present invention is to provide a method for preparing a microbial preparation suitable for preventing contamination and increasing yield of oyster mushroom medium.
상기 목적을 달성하기 위한 본 발명의 방법은 중온성 영역에서 탄수화물, 당 및 단백질 등 대사 되기 쉬운 영양원을 유해성 곰팡이류 및 혐기성 세균에 비해 증식속도가 빨라 우점적으로 이용할 수 있는 활성미생물인 고초균, 효모균과 미생물 증식자체가 증식촉진 물질로 작용하는 광합성세균을 이용하고, 중온성방선균 및 고온성방선균의 항생물질 분비기능을 이용하여 유해성 곰팡이류의 발생을 억제하고 섬유소의 분해효소활성을 이용하여 버섯균사의 증식에 유리한 lignocellulose化를 조장하는 것이다.The method of the present invention for achieving the above object is an active microorganism that can be used predominantly because of the rapid growth rate of nutrients such as carbohydrates, sugars and proteins in the mesophilic region compared to harmful fungi and anaerobic bacteria, such as Bacillus subtilis, yeast and By using photosynthetic bacteria where the microbial growth itself acts as a growth-promoting substance, it suppresses the occurrence of harmful fungi by using the antibiotic secretion function of mesophilic actinomycetes and thermophilic actinomycetes, and uses the degrading enzyme activity of fibrin to proliferate mushroom mycelia. It is to promote lignocellulose that is beneficial to.
따라서 상기 5종의 미생물을 각각의 증식최적조건의 배지조성, 배양 조건으로 준비한 액체, 고체배지에 3∼6일간 배양하고 팽연왕겨, wood chip등의 다공성 식물소재의 담체에 균체를 담지시켜 50℃이하의 온도에서 통풍건조시킨 분말인 미생물제재를 퇴적발효 시 첨가해 줌으로서 기존의 발효과정중에 발생하고 있는 오염의 방지와 버섯수량 증대에 유용하게 쓰일 수 있다.Therefore, the five microorganisms were cultured for 3 to 6 days in a medium and liquid medium prepared for optimal growth conditions and culture conditions for each growth condition, and the microorganisms were supported on a carrier of porous plant material such as bulrush chaff and wood chips to 50 ° C. By adding a microbial material, which is a powder dried at the following temperature during deposition and fermentation, it can be useful for preventing the contamination occurring during the existing fermentation process and increasing the amount of mushrooms.

상기의 활성미생물들을 대량으로 취득하는 기술은 탄소원, 질소원 및 무기원소 등이 함유된 액체배지에 통기, 교반 배양하는 방법이 사용된다.As a technique for acquiring the active microorganisms in large quantities, a method of aeration and stirring culture in a liquid medium containing a carbon source, a nitrogen source, an inorganic element, and the like is used.
탄소원으로는 전분, 포도당 등이 사용되며 질소원으로서는 옥수수 침지액, 대두박 등이, 영양물질로서는 Yeast extract, Malt extract, 기타 염류 등이 사용된다. 따라서 조성된 액체배지에서 적정온도에서 3∼6일간 배양하면 1010cells/㎖ 이상의 고농도 균체배양액을 얻을 수 있다. 또한 고체배양도 조작이 간편하고 경비가 저렴한 이점이 있어 좋은 배양수단의 하나이다. 이 고체배양은 일반적인 코지(국)의 제조방법에 준하면 되고 밀기울, 미강, 곡류등의 배지로 손쉽게 균체배양물을 얻을 수 있다. 상기 배양된 균체는 팽연왕겨, wood chip 등 다공성 식물소재에 담지시켜 50℃ 이하의 온도에서 통풍·건조하여 수분함량을 13% 이하로 조정하면 장시 보존에도 안정한 미생물 제재의 제조가 가능하다.Starch, glucose, etc. are used as carbon sources, corn steep liquor, soybean meal, etc. are used as nitrogen sources, and yeast extract, malt extract, and other salts are used as nutrients.
