Metagenomics unveils the attributes of the alginolytic guilds of sediments from four distant cold coastal environments
Summary Alginates are abundant polysaccharides in brown algae that constitute an important energy source for marine heterotrophic bacteria. Despite the key role of alginate degradation processes in the marine carbon cycle, little information is available on the bacterial populations involved in thes...
