“…The peaks at 1,708 and 1,635 cm −1 were associated with the presence of carbonyl (–C=O) and carboxylate (–COO–) groups, respectively. It was suggested that the formation of carbonyl groups may result from bacterial adhesion and/or biodegradation of the polymer ( Villalobos, Costa & Marín-Beltrán, 2022 ).…”

“…For bioremediation, bacteria were isolated from mangrove forests, waste disposal dumps and sewage treatment plants, and cow dung ( Jadaun et al, 2022 ). In addition, bacterial communities from the surface of multicellular marine organisms belonging to the types Annelida, Cnidaria, Hydrozoa, Polifera and Tunicata were isolated and cultured ( Villalobos, Costa & Marín-Beltrán, 2022 ). Among them, several genera of microorganisms colonizing the plastic were identified.…”

Вiotic factors may be the driving force of plastic fragmentation along with abiotic factors. Since understanding the processes of biodegradation and biological depolymerization of plastic is important, a new methodological approach was proposed in this study to investigate the role of marine invertebrate digestive enzymes in plastic biodegradation. The aim of this study is to evaluate the possibility of enzymatic biodegradation of polyethylene fragments in the digestive gland homogenate of marine invertebrates differing in their feeding type (Strongylocentrotus nudus, Patiria pectinifera, Mizuhopecten yessoensis). Significant changes are found in the functional groups of the polymer after 3 days of incubation in the digestive gland homogenates of the studied marine invertebrates. A significant increase in the calculated CI (carbonyl index) and COI (сarbon-oxygen index) indices compared to the control sample was observed. The results suggest that digestive enzymes of studied organisms may play an important role in the biogeochemical cycling of plastic.

“…This approach is a highly selective and non-destructive method of analyzing functional groups in the structure of the polymer chain, which allows not only to identify the type of polymer, but also to detect changes in its structure. This method was particularly applied to characterize structural changes in plastics initiated by abiotic (temperature, oxygen concentration and UV) and biotic (microorganisms) influences (Skariyachan et al, 2018;Almond et al, 2020;Villalobos et al, 2022;Campanale et al, 2023).…”

The problem of environmental pollution by plastics is global in nature and needs to be addressed as soon as possible. Realization of the importance of this problem contributed to the study of degradation and biodegradation of synthetic polymers. It turned out that the driving force of plastic fragmentation along with abiotic factors can be biotic. Based on the above, we investigated the in vitro biodegradation of polypropylene (PP) fragments in digestive gland homogenates and crystalline styles of the bivalve mollusk Mizuhopecten yessoensis. Fourier transform infrared spectroscopy showed changes in the chemical composition of functional groups on the plastic surface. Enzyme complexes of crystalline styles enhanced the biodegradation of PP fragments to a larger extent than did digestive glands. The results obtained using M. yessoensis as an example suggest that marine phytophagous filter-feeding invertebrates may accelerate the biodegradation of synthetic polymers. The study provides a basis for rethinking the nature of relationships between marine invertebrates and microplastic polluting the marine environment.

“…Over the past 70 years, global plastic production has increased from 1.5 million tons to approximately 359.0 million tons, with an estimated projection of reaching 500.0 million tons by 2025. This trend raises significant concerns within civil society, as MPs are primarily generated through the degradation of larger polymers, a process influenced by physical, chemical, or biological factors ( Cverenkárová et al, 2021 ; Torena et al, 2021 ; Villalobos et al, 2022 ; Osman et al, 2023 ). As microplastics increasingly contaminate the environment, the food chain has also been significantly impacted.…”

“…Consequently, when present in the environment in combination with biotic and abiotic factors, they can undergo transformations leading to the formation of alcoholic or carbonyl groups. This process increases plastic hydrophilicity and provides anchors that facilitate the attachment of bacterial species ( Villalobos et al, 2022 ; Pathak, 2023 ; Thakur et al, 2023 ).…”

IntroductionMicroplastics (MPs) are widely distributed in the environment, causing damage to biota and human health. Due to their physicochemical characteristics, they become resistant particles to environmental degradation, leading to their accumulation in large quantities in the terrestrial ecosystem. Thus, there is an urgent need for measures to mitigate such pollution, with biological degradation being a viable alternative, where bacteria play a crucial role, demonstrating high efficiency in degrading various types of MPs. Therefore, the study aimed to identify bacteria with the potential for MP biodegradation and the enzymes produced during the process.MethodsThe methodology used followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol.Results and DiscussionThe research yielded 68 eligible studies, highlighting bacteria from the genera Bacillus, Pseudomonas, Stenotrophomonas, and Rhodococcus as the main organisms involved in MP biodegradation. Additionally, enzymes such as hydrolases and alkane hydroxylases were emphasized for their involvement in this process. Thus, the potential of bacterial biodegradation is emphasized as a promising pathway to mitigate the environmental impact of MPs, highlighting the relevance of identifying bacteria with biotechnological potential for large-scale applications in reducing MP pollution.
