The use of biodegradable plastics is constantly raising, increasing the likeliness for these polymers to end up in environment. Environmental applications foreseeing intentional release have been also recently proposed, e.g., polyhydroxyalkanoates (PHAs) acting as slow hydrogen releasing compounds stimulate microbial reductive dehalogenation processes. However, effects their into environment on ecosystems still need be thoroughly explored. In this work, PHAs enhance dechlorination polychlorobiphenyls (PCBs) and impact metabolic compositional features resident community investigated laboratory microcosms a polluted marine sediment from Mar Piccolo (Taranto, Italy), compared with recent findings different contaminated Pialassa della Baiona (Ravenna, Italy).
