摘要: <正>从40多个国内外产纤维素酶的菌株中筛选出纤维素分解酶活较高的绿色木霉NF4。该菌在以未经特别处理的稻草粉为主要碳源的固体发酵条件下,每克纤维素每天产纤维素酶活力可达48个国际单位,其酶促反应的最适酸碱度和温度分别是pH4.8和60℃,而半纤维素酶则分别为pH4.2和55℃。

Abstract: A fine strain of cellulolytic fungus Trichoderma viride NF4 was screened out in comparisonwith over 40 cellulolytic strains at home and abroad. NF4 produced high cellulase and hemicellulase onuntreated rice straw powder in solid state fermentation.The cellulase yields of 45 IU/g.·d were quitehigh. The optimum pH and temperature for its collulase activity are PH 4. 8 and 60℃.
