摘 要：
本文首次报道胨冻样芽孢杆菌XDB1和D4B1对烟草灰霉病菌(Botrytis cinerea)的抑制作用。实验表明,XDB1和D4B1的发酵原液和无细胞提取物具有相同的抑菌效果,而经121℃处理30分钟后,抑菌活性丧失。D481菌株的抑菌活性高于XDB1,钾长石作为基质时的活性高于土壤矿物。但是,XDB1和D481对立枯丝核病菌(R..solani)、西瓜尖孢镰刀菌(F.oxysporum)、腐霉(Pythium sp)、小麦全蚀病菌(G.graminis)、烟炭疽病菌(C.gloeosporides)、烟草赤星病菌(A.alternata)、烟草黑胫病菌(P.nicotianae、串珠镰刀病菌(F.moniliforme)和水稻稻瘟病菌(P.grisea)无抑制作用。

摘 要：
The fungistasis of Bacillus mucilaginosus XDB1 and D4B1 against the phytopathogene - Botrytis cinerea was reported firstly in the field. It was demonstrated that the primary fermentation broth and its cell - free extraction possessed the same inhibitory effects on B. cinerea, while the autoclaved broth by 121℃ for 30 minutes had no fungistasis. The fungistasis of D4B1 was stronger than that of XDB1. Broth used Feldspar Mineral Powder as substrate produced deeper suppression than Soil - Extracted Mineral Powder. However, The fungistasis could not been detected, against other phytopathogene Rhizoctonia solani, Fusarium oxysparum, Pythium sp, Gaeumannamyces graminis, Colletotrichum gloeosporides, Alternaria alternata, Phytophthora nicotianae, Fusarium moniliforme and Pyricularia grisea.
