Plastic wastes, widely distributed in the environment, can be transformed into microplastics, posing a huge threat to ecosystems and human health due their stability adsorbability other toxic pollutants (e.g., heavy metals antibiotics). Recently, microbial degradation of (micro)plastics has gained widespread attention because its green sustainable properties. Microbial is based on cascade effects various enzymes secreted by microorganisms, which convert oligomers monomers, or even mineralize them CO2 H2O. The affected multiple factors, such as species, plastic properties, environmental conditions. Currently, limited efficient plastic-degrading microorganisms have been discovered, mechanisms are still unclear. Furthermore, efficiency needs improved for future application. Therefore, this review systematically summarizes sources properties existing plastics, identifies pure cultures mixed degradation, examines influencing factors. In particular, behaviors (micro)plastics, including relevant enzymes, efficiency, mechanisms, were thoroughly discussed. Additionally, augmentation technologies coupling with advanced oxidation, electrochemical, genetic engineering technologies, introduced highlighted potential prospects. This provides reference research development (micro)plastic biodegradation technology.

Expanded polystyrene (EPS) has caused significant pollution in marine environments, with potential EPS-degrading bacteria identified on long-term floating EPS biofilms. However, studies bacterial interactions and consortium reconstruction based in-situ diversity remain limited. Marine wastes of different sizes were collected from subtropical coast Xiamen island, subjected to analyses. Co-occurrence network characterization revealed that Rhodobacterales Rhizobiales play important roles (PS) degradation. Bacterial isolation confirmed Fulvimarina pelagi , Pseudosulfitobacter pseudonitzschiae Devosia nitrariae Cytobacillus kochii oceanisediminis as novel PS-degraders. Based their abundance situ PS degradation activity, a was constructed, constituted F. P. halotolerans . O. granulosus showed high capability weight loss by 18.9% 45 days. These results contribute plastic remediation resources recycling.
