Isolation and identification of a bacterial strain that inhabits the growth of Enteromopha prolifera |
| |
| Abstract: | 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. |
