Studies on Cellulase -Part. 2. The Physiological and Morphological Properties of the Cellulase producing Strains Ku-3371 and Ku-4383-

Cellulase에 관(關)한 연구(硏究) -제 2 보(第 2 報) Cellulase 생성균(生成菌) Ku-3371, Ko-4383 균주(菌株)의 균학적(菌學的) 성질(性質)-

In the previous paper, two strains of cellulase producing microorganism were isolated from night soil samples using shaking culture. This report deals with the physiological and morphological tests carried out according to the methods of Toyama and Chung. 1. Two strains, Ku-3371 and Ku-4383 which should the best growth in Czapek.s liquid medium, were identified as Trichoderma viride. 2. These strains grew the best at about $30^{\circ}C$ and the optimum pH values of growth in Czapek's liquid medium was 4.0. 3. These mould strains utilized monosaccharide as its carbon source and can utilized sodium glutamate, peptone and nitrate form nitrogen but other inorganic nitrogen compoumd are unable to use as its nitrogen source.

1. 전보(前報)에서 분리한 두 균주(Ku-3371, Ku-4383)는 다 같이 형태학적으로 Trichoderma viride에 일치한다. 2. 이들 균주(菌株)들의 생육 최적 pH는 4.0이고 생육 최적온도는 $30^{\circ}C$이다. 3. 그리고 이들 균주(菌株)들의 탄소원은 단당류(單糖類)가 좋았고 질소원은 초산태(硝酸態) 질소가 좋았으며 특히 구루타민산(酸)소다는 더욱 좋은 질소원이다.
