摘要: 在南海深海海泥中采用平板法分离具有抑菌活性的微生物,以纸片法研究其抗菌活性,对分离到的活性细菌进行16S rRNA测序并构建系统进化树,对细菌进行生长特性研究。结果表明,从海泥中分离到9株具有抑菌活性的微生物,分别属于BacillusSalinicola属。菌株j65可在含盐率20%的条件下生长,除菌株gu8外其他菌株均可在pH 6~10的环境下生长。

关键词: 海洋微生物, 分离鉴定, 抑菌试验, 系统进化树

Abstract: The bacteria which had antibacterial activity was isolated from the sediments of South China Sea by plate isolation.The antibacterial activity of isolates were identified by paper disk method. The active isolates were identified by 16S rRNA sequencing and the phylogenetic tree constructed by neighbour-joining method. The growth characteristics of bacteria were studied. The results showed that nine active antibacterial bacteria belonging to genus Bacillus and Salinicola were isolated from sediment samples. It was indicated that strain j65 could grow at the concentration of 20% NaCl,and all strains could grow at the range of pH 6~10,except for strain gu8.

Key words: marine microorganism, isolation and identification, antibacterial experiment, phylogenetic tree
