摘要
从青岛近海海泥中分离了57株细菌,通过毒性实验,得到了一株对浒苔具有较强毒性的细菌EP23。对该菌株进行了菌落、菌体形态学观察、生理生化特征分析及16S rDNA序列分析,鉴定该菌为弯曲芽孢杆菌(Bacillus flexus)。该菌培养液高速离心的上清液对浒苔具有较强毒性,表明弯曲芽孢杆菌EP23是通过分泌胞外物质的间接方式进行的。
Fifty-seven bacteria strains were isolated from sea mud at Qingdao. Strain EP23 was found to have algae-lytic activity toward Enteromopha prolifera. Strain EP23 was identified as Bacillus flexus by morphological characters, physiological characteristics, and 16S rDNA sequence analysis. After ultracentrifugation, the bacterial culture supernatant displayed algae-lytic activity toward Enteromopha prolifera, indicating that certain extracellular substances produced by the strain are responsible for the algae-lytic ability.
