Bacterial exopolysaccharides from extreme marine habitat of Southern Ocean: Production and partial characterization

ABSTRACT 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 mic...
