Bacterial bioconversion of macroalgal biomass
Macroalgae are dominant primary producers in coastal regions, considered a global carbon sink that pumps atmospheric CO2 and stores it as organic matter. Marine bacteria that degrade this algal biomass are thus crucial to ecosystems functioning, especially in today’s context of global change, since they influence the carbon balance already threatened by human activities and pollution. These bacteria are also a vast reservoir of novel enzymatic activities to produce high-value compounds with potential applications in human, animal and plant health. Among marine heterotrophic bacteria, members of the class Flavobacteriia are often recognized as master recyclers of algal biomass, interacting both with algal tissues and secreted algal compounds. In this talk, I will highlight some of our past and current research investigating the natural diversity, substrate specificity and metabolic interactions of algae-degrading flavobacteria, as well as their enzymatic machineries and regulation strategies to access and degrade macroalgal biomass. This work integrates temporal monitoring of field populations, experimental approaches using natural communities, and studies of the model flavobacterial species Zobellia galactanivorans.
