Marine algae convert a substantial fraction of the carbon dioxide they fix into various polysaccharides. Bacteria specialized on the remineralization of these polysaccharides often feature genomic clusters, termed polysaccharide utilization loci (PULs). Such PULs are often prevalent in, but not limi...
About one half of the global, biogenic carbon dioxide fixation into organic matter is driven by microscopic algae in the surface oceans. These microalgal activities generate, among other molecules, polysaccharides that are food for and recycled by bacteria with polysaccharide utilization loci (PULs)...

Arabinose and galactose are major components of both particulate and dissolved organic matter. They often constitute polysaccharides such as arabinogalactan. Field studies have demonstrated a turnover of arabinogalactan, but enzymes and organisms involved have not been explored. In this study, the d...
