Abstract

This study aims to isolate and identify culturable marine bacteria from 4 locations in the San Jorge Gulf.A total of 1,532 strains were isolated using oligotrophic, heterotrophic and hydrocarbondegrading bacteria media, and identified with reference to bacterial fatty acid methyl ester (FAME) profiles.Gram-negative bacteria were the most abundant, Pseudoalteromonas comprised 17% of the isolated bacteria, followed by Pseudomonas, with 11.14%.The Gram-positive bacteria genera identified were Staphylococcus, Bacillus and Micrococcus.In addition, those bacteria able to degrade hydrocarbons were: Arthrobacter, Dietzia, Acinetobacter, Microbacterium, Micrococcus, Bacillus, Pseudomonas and Pseudoalteromonas.
