海南红树林根系土壤中可培养细菌的多样性分析
Diversity of culturable bacteria from the soil of root system of mangrove forest of Beigang island in Hainan Province
摘要
Abstract
To investigate the diversity of soil bacteria in the root system of mangrove forest and potential microbacteria sou-rces in Hainan Province, we collected ten soil samples from Beigang island in December 2012. The samples were treated by the plate dilution method to isolate culturable marine bacteria. The diversity of marine bacteria was examined based on 16S rRNA gene sequence analysis. Totally 70 representative strains were selected from 122 isolates, and they were further sequenced and subjected to phylogenetic analysis. The bacterial population was composed of 4 major lineages, Proteobacteria (66%, with a predominance of Gammaproteobacteria), Bacteroidetes (19%), Firmicutes (11%) and Actinobacteria (4%). These culturable bacterial isolates belonged to 30 genera and 47 species. There were 9 strains identified as potential novel species and 2 strains were identified as potential novel genus. This study indicated that there was high bacterial diversity in the soil of root system of mangrove forest of Beigang island and many isolates were the characteristic groups in mangrove forest.关键词
