摘　　要：为获得银杏叶饲料纤维素酶高产菌株,对从古银杏土壤中分离出的40株真菌进行发酵试验,结果表明:在供试各类真菌中,曲霉菌产生的纤维素酶分解银杏叶中的纤维素能力最强,其次是青霉,再其次是毛霉和木霉。若用于真菌发酵产纤维素酶的生产中,曲霉和青霉是比较优良的菌种,其中编号为YX201040C的黑曲霉和编号为YX2010216的焦曲霉最为合适。To obtain fungus that can generate cellulase productively,the fermentation experiment of 40 strains of fungi isolated from ancient ginkgo soil was carried out.According to the experiment,we found that cellulose generated by Aspergillus can degradate the cellulose in ginkgo leaf fastest,Penicillium is in the next place,mucoraceae and trichoderma are in the third place.If we want to apply fungus to generate cellulose,Aspergillus and Penicillium are good selection,among them,Aspergillus niger named YX201040C and Aspergillus ustus named YX2010216 are the best choice.
