Antarctic sponges from the Terra Nova Bay (Ross Sea) host a diversified bacterial community
Abstract Sponges represent important habitats for a community of associated (micro)organisms. Even if sponges dominate vast areas of the Antarctic shelves, few investigations have been performed on Antarctic sponge-associated bacteria. Using a culture-dependent approach, the composition of the bacte...
