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.
