在香蕉枯萎病园区中,从土壤中分离获得一株细菌HN-1,并进行对峙培养、孢子萌发抑制测定。结果表明：HN-1对香蕉枯萎病菌的菌丝生长、孢子萌发具有良好的抑制效果。经形态特征、生理生化特征和16SrDNA序列测定和分析,将HN-1鉴定为短短芽孢杆菌（Brevibacillus brevis）。与病原真菌对峙培养的结果表明,该菌株对供试的15种植物病原真菌均有很好的抑制作用。

A strain HN-1 was obtained from the soil in a field heavily infected with Fusarium oxysporum f.sp.Cubense（FOC）.Antagonism of the strain against FOC was tested via dual-culture,inhibition test on conidia germination.Results showed that HN-1 effectively inhibited mycelium growth and conidia germination.Strain HN-1 was identified as Brevibacillus brevis according to its characteristics in morphology,physiology,biochemistry and 16S rDNA sequence.The strain showed high suppression effect on 15 fungal pathogens in the dual-culture trials with fungal pathogens.
