Biodegradable polymers offer a potential solution to marine pollution caused by plastic
waste. The marine biofilms that formed on the surfaces of poly(lactide acid) (PLA) and poly(3-
hydroxybutyrate-co-3-hydroxyvalerate) (PHBV) were studied. Bioplastics were exposed for 6 months
to marine conditions in the Mediterranean Sea, and the biofilms that formed on their surfaces were
assessed. The presence of specific PLA and PHBV degraders was also studied. PHBV showed
extensive areas with microbial accumulations and this led to higher microbial surface densities
than PLA (4.75 vs. 5.16 log CFU/cm2
). Both polymers’ surfaces showed a wide variety of microbial
structures, including bacteria, fungi, unicellular algae and choanoflagellates. A high bacterial diversity
was observed, with differences between the two polymers, particularly at the phylum level, with
over 70% of bacteria affiliated to three phyla. Differences in metagenome functions were also
detected, revealing a higher presence of proteins involved in PHBV biodegradation in PHBV biofilms.
Four bacterial isolates belonging to the Proteobacteria class were identified as PHBV degraders,
demonstrating the presence of species involved in the biodegradation of this polymer in seawater.
No PLA degraders were detected, confirming its low biodegradability in marine environments. This
was a pilot study to establish a baseline for further studies aimed at comprehending the marine
biodegradation of biopolymers. [-]
