Bacterial exopolysaccharides from extreme marine habitat of Southern Ocean: Production and partial characterization
Deep marine microorganisms survive under extreme ecological settings and harsh environmental conditions of low temperature, high salinity, and high atmospheric pressure making it significant of scientific interest. Southern Ocean (SO) is one such example of deep marine ecosystem and the microorganis...

Deep marine microorganisms survive under extreme ecological settings and harsh environmental conditions of low temperature, high salinity, and high atmospheric pressure making it significant of scientific interest. Southern Ocean (SO) is one such example of deep marine ecosystem and the microorganisms inhabiting in such hostile environment may produce different bioactive secondary metabolites.

The present study involves isolation of exopolysaccharides (EPSs) from three potent SO (Indian Sector) bacteria, optimization of the EPS production and partial characterization of them.
