The results obtained were as follows : 1. Molds which were grown in the liquid medium containing heat water treated bagasse as a sole carbon source were isolated from the soils of sugarcane fields and others. Most of the isolates belonged to the species of Trichoderma. 2. Crude enzyme preparations were prepared from the bagasse-Koji extracts of the isolates. Compared with heat water-treated bagasse, NaOH-treated bagasse was well decomposed by the preparations. 3. The crude enzme preparation of Trichcderma No.353,newly isolated, decomposed considerably heat water-treated bagasse, as well as NaOH-treated bagasse. The degree of the decomposition was affected by the concentration of NaOH used for the treatment of bagasse. The bagasse treated with 0.5% NaOH was most highly decomposed. 4. The products of the enzymatic decomposition of treated bagasse, Avicel and cellobiose were investigated by means of paper chromatography. Cellobiose and glucose were produced from heat water-treated bagasse and Avicel. Xylose, in addition to cellobiose and glucose, was produced from NaOH-treated bagasse, and glucose from cellobiose., 紀要論文}, pages = {279--290}, title = {甘蔗バガスの利用に関する研究 : 第 2 報 バガス分解カビの分離ならびに酵素的性質(農芸化学科)}, year = {1972} }
