Cover Story: Phototrophic mixed cultures (PMC) are versatile systems which can be applied for waste streams valorisation and production of added-value compounds, such as polyhydroxyalkanoates (PHA). This work employed DNA sequencing, fluorescence in situ hybridization (FISH), Nile blue staining, and morphological observations to deepen our current knowledge of the bacterial communities present in PHA-producing PMC systems. Links between microbial communities and their PHA production performance were established and microbial groups with high PHA accumulation capacity were identified, namely, Chromatiaceae members. Knowledge of the operating conditions that maximize the presence of such groups and PHA storage will help to define improved operational strategies for PHA production with PMC systems.
