Psychrobacter species enrichment as potential microplastic degrader and the putative biodegradation mechanism in Shenzhen Bay sediment, China

College of Food Science and Engineering, Inner Mongolia Agricultural University, Hohhot 010018, China oxidoreductases, hydrolases, transferases, ligases, lyases, and isomerases. We propose a putative mechanism for MP biodegradation, involving the breakdown of long-chain plastic polymers and subsequent oxidation of short -chain oligomers, ultimately leading to thorough mineralization.
