“…More recently, the focus has shifted from studying specific strains or enzymes to examining the plastisphere community as a whole “degradation unit” ( Jacquin et al, 2019 ; Yuan et al, 2020 ; Eronen-Rasimus et al, 2022 ; Joshi et al, 2022 ; Taipale et al, 2022 ; Cai et al, 2023 ; Maheswaran et al, 2023 ; Miao et al, 2023 ; Niu et al, 2023 ; Vaksmaa et al, 2023 ; Yu et al, 2023 ; Zhu et al, 2023 ). Various key microbial taxa can cooperate and show enzymatic potential for polymer biodegradation ( Li K. et al, 2023 ; Li W. et al, 2023 ; Miao et al, 2023 ), also promoting changes in surface material properties, including chemical composition, morphology roughness, formation of holes and cracks, and weight loss.…”

The plastisphere, a unique microbial biofilm community colonizing plastic debris and microplastics (MPs) in aquatic environments, has attracted increasing attention owing to its ecological and public health implications. This review consolidates current state of knowledge on freshwater plastisphere, focussing on its biodiversity, community assembly, and interactions with environmental factors. Current biomolecular approaches revealed a variety of prokaryotic and eukaryotic taxa associated with plastic surfaces. Despite their ecological importance, the presence of potentially pathogenic bacteria and mobile genetic elements (i.e., antibiotic resistance genes) raises concerns for ecosystem and human health. However, the extent of these risks and their implications remain unclear. Advanced sequencing technologies are promising for elucidating the functions of plastisphere, particularly in plastic biodegradation processes. Overall, this review emphasizes the need for comprehensive studies to understand plastisphere dynamics in freshwater and to support effective management strategies to mitigate the impact of plastic pollution on freshwater resources.

“…This is attributed to the addition of various substances during their manufacturing process, such as pigments, plasticizers, and flame retardants. Additionally, due to their chemical-physical characteristics, they exhibit high durability, requiring an extended period for degradation in the environment ( Cai et al, 2023 ; Niu 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.
