초록
섬유성 물질을 자화(資化)하는 미생물을 자연계로 부터 분리하여 효소생산 및 당화조건을 검토하였다. 분리 균주 256주 중 효소생산에 가장 유효하다고 인정되는 Aspergillus fumigatus KC-1을 우수 균주로 선발하였다. 본 균은 alkaline peroxide로 전처리한 현사시 목분 1%를 탄소원으로하여
The cellulolytic activities of Aspergillus fumigatus KC-1 was investigated, which showed the most active producer of cellulase among the 256 strains of cellulose-decomposing microorganisms screened in our laboratory. All the examined cellulolytic activities (filter paper-, Avicel-, cotton-, CMC-, salicin- and xylansaccharifying activity) in a culture of A. fumigatus KC-1 grown on 1% popular sawdust pretreated with peroxide alkaline reached a maximum within 4-5 days. The optimum pH and temperature for the enzymatic activity was found to be pH 4.5 and
