|
The 635 strains of Korean Sspergilli are isolated, cultured purely, and their Avicelase, CMCase and Salicinase activities are measured, in order to select the best strains exhibiting predominant cellulase activities, and to survey their cellulase activities in taxonomical and ecological viewpoints. Strains No.175, 255 and 254 are selected as the best Avicelase producing strains, strains No.131, 151 and 116 are selected as the best CMCase producing strains, and strains nO.456, 457 and 253 are selected as the best Salicinase producing strains. A niger group and A, clavatus group exhibited the highest activities of Avcelase and Salicinase, respectively. A. niger group and A, clavatus groups are showed the highest activities of CMCase. Among the different species tested, the activities of Avicelase, CMCase and Salicinase are highest in A.phoenicis, A.clavatus, and A. japonicus and A.giganteus, respectively. Cellulase activities of Aspergilli from the inland regions of Korea are higher, more or less, than those of the strains from the other regions. Avicelase and CMCase activities of Aspergilli isolated from bread and Korean cake are relatively higher, and Salicinase activities of the strains isolated from the cereals are higher than those of the strains from the other habitat substrate.
