Journal highlight -  Bacterial communities associated with Microcystis colonies differ from free-living communities living in the same ecosystem

The search for a better understanding of why cyanobacteria often dominate phytoplankton communities in eutrophic freshwater ecosystems has led to a growing interest in the interactions between cyanobacteria and bacteria. Against this background, we studied the location of bacteria within Microcystis colonies, and compared the structural and phylogenetic diversity of Microcystis-attached and free-living bacterial communities living in the same French lake, the Villerest reservoir. Our findings suggest that Microcystis colonies constitute a distinct habitat for bacteria living in freshwater ecosystems, and that direct and indirect interactions (cell lysis, nutrient recycling, etc.) may occur between them inside these colonies.

The work is published in the SfAM journal, Environmental Microbiology Reports as follows: Parveen, B., Ravet, V., Djediat, C., Mary, I., Quiblier, C., Debroas, D. and Humbert, J.-F.
