摘　　要：从工业污水中分离出高效降解萘的菌株黄杆菌(Flavobacterium)ND3,该菌株还能降解水杨酸、对羟基本甲酸和苯乙酸,对氨苄青霉素(100μg·ml^(-1))和氯霉素(150μg·ml^(-1))具有抗性,含有一个大质粒.适合该菌株生长的最适培养条件被确定.在最适培养条件下,ND3菌株对萘的降解率达98%以上.Flavobacterium sp. strain ND3, effectively degrading naphthalene, was isolated from industrial waste. The strain was shown to be capable of also degrading salicylate, p-hy-droxybenzoic acid and phenylacetic acid, resisting ampicillin (100μg·ml-1) and chloram-phenicol (150μg·ml-1), and carrying a large plasmid. The optimum conditions for the growth of this strain was determined. The degradative rate of naphthalene of the strain in optimum condations was more than 98%.
