Abstract: Benthic sediment samples, from both east and west coast of peninsular India were evaluated for the different species of vibrios and their exoenzyme profile. About 800 isolates of Vibrio sp. were isolated and screened for hydrolytic exoenzymes. More than 91% of isolates showed multiple extracellular enzyme profile, synthesizing more than two hydrolytic enzymes. Hydrolytic exoenzyme production was more active during monsoon season. Among the species of vibrios, V. furnissi (30%) was dominant, followed by V. harveyi (23.75%), V. neries (15%) and V. parahaemolyticus (11.25%). Vibrios from the benthic environment were a markedly diverse group playing an important role in mineralization process in the benthic environments.
