Bakterielle Mechanismen der marinen Polysaccharidverwertung

Abstract

The oceans have been compared to a “global heterotrophic digester”.This is due to the high productivity of microalgae and the rapid turnover of the produced biomass by microbes. A major part of the algal
biomass consists of diverse polysaccharides which belong to the most complex polymer structures in nature. These marine sugars are
decomposed by specialized bacteria, mainly of the phyla Bacteroidetes and Gammaproteobacteria, which possess dedicated conserved geneclusters encoding a remarkable diversity of carbohydrate-active
enzymes.
