简介：这研究被设计从A孤立endophytic真菌。mongholicus(在东北中国成长)决定他们是否能生产bioactive代谢物。endophytic真菌的四紧张(拉紧16，17，23和75)成功地从A被孤立。用表面消毒方法的mongholicus。根据ITS-rDNA序列分析，拉紧16和75作为镰刀霉oxysporum被识别，并且拉紧17和23作为Bionectriaochroleuca被识别。我们使用了Box-Behnken设计(BBD)优化液体发酵条件并且获得最大的房间干燥重量(CDW)产量。最佳的参数在下列试验性的条件下面被获得：第28i的温度口香糖的年龄。与那，新鲜口香糖增加了拍的成功。第二，本地人比较喜欢在温暖的季节期间拍，吗我们由决定Xac生长在30略潤潭慮?楤業畮慴?是最好的验证了哪个?桓杩汥慬????????????????????????楦浲獵??‰???堠湡桴浯湯獡？？
