摘　　要：从中国武汉地区水稻白叶枯病叶上分离出一株真菌B-3543,它产生一种新的肽类抗生素,对多种革兰氏阳性和阴性细菌有抗菌活性。其中,对水稻白叶枯病菌抗菌作用最强,其最低抑菌浓度为0.2μg/ml。根据该菌株的形态特征、培养特征和生理特性,鉴定为桃色拟青霉B-3543菌株。A fungus strain B-3543 isolated from a rice leaf with lesion caused by bacterial leaf blight in Wuhan, China was found to produce a new peptide antibiotic which exhibited antimicrobial activity against several Gram-positive and Gram-negative bacteria, most strongly against Xanthomonas campestris pv.oryzae.The minimal inhibitory concentration against X.campestris pv. oryzae was 0.2μg/ml. From its morphological, cultural and physiological characteristics, the strain was determined to be Paecilomyces persicinus B-3543.
