Characterization of antibiotic resistant and enzyme producing bacterial strains isolated from the Arabian Sea.

ABSTRACT: Marine bacteria are known to produce many bioactive molecules and extracellular enzymes of commercial importance. We have investigated the bacterial diversity of the coastal area of Karwar, Karnataka State, India. Among these bacterial isolates, five bacterial strains were selected and identified by their morphological, biochemical characteristics and phylogenetic analysis based on 16S rRNA gene sequences. The identified bacterial isolates, Bacillus toyonensis PNTB1, Lysinibacillus sphaericus PTB, Vibrio vulnificus PMD, Shewanella MPTDBS, and Pseudomonas chlororaphis PNTB were characterized for their tolerance to salt and antibiotics. Vibrio vulnificus PMD showed maximum tolerance at higher concentration of salt than other bacteria. These bacterial strains were screened for the production
