Two bacterial strains isolated from plastic-coated biofilm in a Thai mangrove — Lysobacter sp. and Nitratireductor kimnyeongensis — degraded 35% and 23% of polyethylene microplastics by weight within 30 days, using distinct metabolic pathways confirmed by genomic analysis. Finding effective plastic-degrading microbes in mangrove environments is significant because mangroves are both major accumulation zones for coastal plastic pollution and highly biodiverse ecosystems where natural microbial solutions could potentially be harnessed for in-situ cleanup.
