一种降解纤维素的曲霉及其生产的菌剂
摘要：
本发明提供一种纤维素降解菌及其生产的菌剂，属于生物技术领域，YN1菌种接种于PDA平板培养基、PDA液体培养基、种子罐培养基、生产罐培养，发酵结束后菌体的有效活菌数达到1亿个/ml以上。YN1菌株经液体发酵培养，内切酶、外切酶、β-糖苷酶、木聚糖酶活及总纤维素酶活性分别为95.7U/mL、14.6U/mL、20.5U/mL、71.6U/mL和26.6U/mL。YN1菌株经固体发酵培养，内切酶、外切酶、β-糖苷酶、木聚糖酶活和总纤维素酶活性分别为1192.2U/g、100.6U/g、136.9U/g、1118.0U/g和210.7U/g。YN1在7d内可降解41.87％的秸秆，31.59％的稻壳。
摘要（英）：

The invention provides bacteria for degrading cellulose and microbial inoculum prepared by same, which both belong to the bio-technology field. YN1 microbial strain is added to a PDA plating culture medium, PDA liquid culture medium, a seed tank culture medium and a production culture medium, and the effectively live bacteria of the microbial strain reaches over 100 million/ml. After the YN1 bacterial strain is cultivated through fermentation, the activity of incision enzyme, excision enzyme, beta-glycosidase, xylanase and cellulase is respectively 95.7 U/mL, 14.6 U/mL, 20.5 U/mL, 71.6 U/mL and 26.6 U/mL. After the YN1 bacterial strain is cultivated through solid fermentation, the activity of incision enzyme, excision enzyme, beta-glycosidase, xylanase and cellulase is respectively 1192.2U/g, 100.6 U/g, 136.9 U/g, 1118.0 U/g and 210.7 U/g. The YN1 microbial strain can degrade 41.87% straws and 31. 59% rice husks in 7 days.
