海洋贝类附生细菌区系分析及弧菌拮抗菌的筛选
Isolation and biodiversity analysis of bacteria attached on the marine shellfish and selection of vibrios-antagnism bacteria
摘要
Abstract
A preliminary screening of bacteria attached on the marine shellfish from six marine shellfishes(Mytilus edulis, Concha ostreae, Ruditapes variegate, Anadara uropygimelana, Placopecta magellanicus, and Ovula ovum) in the coastal waters of Weihai yielded 100 isolates, among which 45 strains were selected for further analysis. To investigate the phylogenetic position of these strains, the 16S rDNA sequences were cloned, sequenced, and com- pared with those of related strains and a molecular phylogenetic dendrogram was constructed based on genetic dis- tance analysis. The strains were classified as members of genera Arthrobacter, Bacillus, Bizionia, Brevundimonas, Cellulophaga, Cobetia, Gelidibacter, Kocuria Krokinobacter, Lacinutrix, Marinobacter, Microbacterium, Micrococcus, Paracoccus, Planomicrobium, Pseudoalteromonas ,Psychrobacter, Salinibacterium, Shewanella, Tenaci- baculum, and Vibrio. The antimicrobial activity of the 100 strains were screened by the agar flat seeding method. The experiment results showed that 2 strains had obvious antimicrobial activity.关键词
