PhD project: Molecular mechanism of enzymatic recycling of anionic glycans by marine microbes
An important step in the (marine) carbon cycle is the remineralisation of algal polysaccharides by heterotrophic bacteria. Marine algae consist of up to 70 % of polysaccharides, which physically support the thallus of macroalgae, have storage properties or are part of extracellular transparent exo-polymer particles (TEP). Polysaccharide-degrading bacteria specialize on glycans resulting in a pronounced niche partitioning with respect to algal polysaccharide degradation during and after algal blooms. Studying the degradation mechanisms of abundant key degraders will contribute to our knowledge on the ecophysiology of marine bacteria, and thus to our understanding of the biogeochemical cycles in the oceans.
In this PhD project, we investigate the utilization of the anionic polysaccharide fucoidan, the main cell wall component of brown seaweed. In more particular, we study the molecular mechanisms of putative CAZymes in order to gain insights into the remineralisation of fucoidan by heterotrophic bacteria.
