Degradation of subµ-sized bioplastics by clinically important bacteria under sediment and seawater conditions: Impact on the bacteria responses.
Summary
Researchers found that clinically important bacteria colonized submicron-sized bioplastic particles in both seawater and sediment and showed biochemical stress responses to the bioplastics. The ability of pathogens to form biofilms on bioplastic surfaces in marine environments raises concerns that bioplastics, like conventional plastics, could act as vectors for disease-causing microorganisms.
In this study, we investigated the interaction of submicron-sized bioplastics with environmentally and clinically important bacteria under seawater and sediment conditions. To examine the relationship between submicron-sized bioplastics and bacteria in seawater and sediment, we focused on the bacterial activation and their biochemical key events toward the protein, carbohydrate, lipid, and antioxidant response. In addition, culture-dependent biofilm formation on submicron-sized bioplastics and their characterization was performed. The results indicated that selected bacteria increased their viability both in seawater and sediment with the submicron-sized bioplastics in that the bioplastics decreased their mass at the level of 10-23%. However, the activation level and mechanism affected the polymer type, bacteria, and environmental media, and submicron-sized bioplastics promoted biofilm formation with enhancing basophilic characteristics of biofilms.

Similarities and Discrepancies Between Bio-Based and Conventional Submicron-Sized Plastics: In Relation to Clinically Important Bacteria.
This study compared the effects of bio-based and conventional submicron-sized plastic particles on clinically important bacteria, finding that bioplastics interacted with bacteria in ways that differed from but were not uniformly less harmful than conventional plastics. The results suggest that bioplastics are not necessarily safer than conventional plastics in terms of their interactions with microorganisms.

This study compared how clinically important bacteria form biofilms on bio-based versus conventional plastic surfaces of similar size, finding differences in biofilm formation patterns between bioplastics and their conventional equivalents. The results suggest that the push to replace conventional plastics with bioplastics should consider how these materials interact with potentially harmful bacteria.
Bioplastics in the Sea: Rapid In-Vitro Evaluation of Degradability and Persistence at Natural Temperatures
Researchers evaluated the marine degradability of multiple bioplastic materials at natural seawater temperatures, finding that most bioplastics persist in ocean environments rather than degrading quickly, challenging assumptions that bioplastics represent a straightforward solution to marine plastic pollution.
Biofilm development as a factor driving the degradation of plasticised marine microplastics
Researchers investigated how natural marine biofilms drive the degradation of plasticized microplastics. The study found that biodegradation was dependent on polymer type, plasticizer type, and time, with polystyrene containing bisphenol A showing the most degradation, coinciding with increased abundance of putative biodegradative bacteria in the colonizing biofilm.
