Biosurfactants production by the quinoline degrading marine bacterium Pseudomonas sp. strain GU 104, and its effect on the metabolism of green mussel Perna viridis L.

Abstract

Biosurfactants produced by bacteria in marine ecosystems are involved in the degradation of hydrocarbons. In the present study, large-scale production of biosurfactants was demonstrated in a quinoline degrading marine bacterium Pseudomonas sp. strain GU 104. Studies were also carried out in experimental set ups to understand the effect of biosurfactants, along with the metabolites of quinoline, on the physiology of the green mussel Perna viridis. Acetylcholinesterase (AchE), lactate dehydrogenase (LDH), phenoloxidase and a-amylase activities from specific organs were analysed. The findings of the present study indicate that biosurfactant, as well as quinoline intermediates, produced by Pseudomonas sp. strain GU 104 do not have a significant effect on the physiology of Perna viridis.
