Abstract
The marine environment envelops an enormous natural assorted diversity and can be considered as an unexplored domain. Diversion of biodiversity is an important part of ensuring the safety and stability of the marine ecosystem. The present study aimed to isolate and characterized the marine halophilic bacteria from the Southeast coast of Tamil Nadu, India. Based on colony morphology the isolated bacteria was characterized by gram staining and biochemical test. The isolated marine halophilic bacteria were screened and identified with a phylogenetic analysis of 16S rRNA gene sequence determined. The result revealed the phylogenetic analysis using 16S rRNA sequence indicated that 6 bacterial isolates belong to Gram-positive phylum of Firmicutes (CARE-V2 Bacillus flexus, CARE-V12 Virgibacillus halodenitrificans, CARE-V17 Virgibacillus salaries, CARE-V29 Jeotgalicoccus huakuii, CARE-V33 Oceanobacillus iheyensis, and CARE-V34 Virgibacillus sp), and 6 bacterial strains accord to Gram-negative phylum of proteobacteria (CARE-V3 Halomonas sp, CARE-V5 Oceanimonas sp, CARE-V9 Bacterium, CARE-V10 Halomonas salifodinae, CARE-V14 Halomonas venusta, CARE-V31 Salinivibrio sp). This study summarized the marine halophilic bacteria and the diversity of marine microorganisms from the Southeast coast of Tamil Nadu.
