Sodium hypochlorite를 이용한 여름 느타리버섯 배양 연구
이호용,신창엽,이영근,민봉희 大邱大學校附設 基礎科學硏究所 1998 基礎科學硏究 Vol.15 No.2
The sterilizing potential and control on mycelial growth of sodium hypochlorite(SHC) were studied. The spawn, composed of cotton waste, was treated with 125, 250 and 500ppm of SHC. The treatment of 500ppm of SHC showed the best mycelial growth and fruit body formation for Pleurotus sajor-caju. The sterilizing potential on 500ppm of SHC showed higher effect than 125ppm. The mycelial growth was slightly inhibited at all of SHC treatment, but also duration for fruit body formation was shortened 7-11 days compared with conventional method. Results indicate some possibilities that the treatment of SHC protects bacterial disease and contamination on substrate without reducing food quality. In addition, it is able to grow of mycellium and form the fruit body of Pleurotus sajor-caju without sterilizing and fermentation. Application of SHC in substrate bring about the reduction of expenditure and is helpful to increase of profit in a farm.
Pleurotus ostreatus 균사의 생장 촉진 효과를 나타내는 고온성 곰팡이의 특징
이영근,김준호,이호용,민봉희,김원록,송인근,현성희,장화형,신창엽 한국균학회 2000 韓國菌學會誌 Vol.28 No.3
The mycelial growth of Pleurotus ostreatus in compost is strongly stimulated by solid-state fermentation with thermophilic fungi which were isolated from oyster mushroom compost. The biochemical characteristics of these thermophilic fungi were investigated. Cellulase and ligninase activities were not detected by clear zone effect on CMC and lignin media. All of thermophilic fungi grew well with high mycelial density on xylan media and the growing rate of Sepedonium sp. S-2 observed very high. In results of MUF-test, extracellular enzyme activity of Sepedonium sp. S-2, and S-5 measured very high. On the compost after high temperature fermentation with Sepedonium sp. S-2 and S-5, the mycelial growing rate of Pleurotus ostreatus was increased about 50% and it also showed the inhibiting effect on mycelial growth of Trichoderma sp. SJG-51. Isolated thermophilic fungi, Sepedonium sp. S-2 and S-5 were expected as very useful organism for making oyster mushroom compost.
