摘要
放线菌YH-1是对玉米茎腐病有较强拮抗作用的菌株。为了明确该菌株的分类地位,根据其形态观察、培养特征、生理生化特性、细胞壁组分和16 S rDNA序列比对分析,鉴定该菌株为弗氏链霉菌YH-1。生物学特性结果表明：菌株YH-1在pH值3-10范围内均能生长,较适生长pH为7-8,较适生长温度为28-30℃,能广泛利用各种碳、氮源。
An actinomycete strain YH-1 is antagonistic against Fusarium graminearum. We observed the morphological, cuhural, physiological, biochemical characteristics, cell wall components and 16S rDNA sequences analysis to ensure the taxonomic status of actinomycete strain YH- 1, identified strain YH- 1 as Streptomyces fradiae, and investigated the biological characteristics of YH-1. The pH for YH-1 growth is 3-10, the optimal pH is 7-8, the optimal temperature is 28 ℃-30 ℃, and the carbon and the nitrogen sources are broadly utilized.
