ClearMarine bacteria capable of enzymatic degrading of low- and high-density polyethylene: Toward sustainable mitigation of marine microplastic pollution
Scientists discovered ocean bacteria that can break down common plastic types found in marine pollution, with some bacteria destroying up to 17% of the plastic in lab tests. These naturally occurring bacteria could potentially be used to help clean up the tiny plastic particles that contaminate our oceans and eventually enter our food chain through seafood. While still in early research stages, this finding offers hope for a biological solution to reduce the microplastics that may pose health risks when we consume contaminated fish and shellfish.

Researchers analyzed all publicly available genetic data from microbes living on plastic debris worldwide and found that while plastic-eating bacteria are rare in most environments, rivers appear to be hotspots for novel plastic-degrading organisms. They also created a freely accessible database of these plastic-associated microbes, which could accelerate efforts to develop biological solutions for plastic pollution.

This review explores how metagenomics, the study of genetic material from environmental samples, is helping scientists identify microorganisms that can break down plastics. The paper covers the methods used to find and characterize plastic-degrading bacteria, as well as the environmental consequences of plastic degradation including health risks from inhaling and ingesting microplastics. While biological solutions to plastic pollution show promise, the review notes that more research is needed to develop effective, scalable approaches.

Microplastic pollution in aquatic environments: a systematic review of bacterial degradation efficacy, mechanisms, and future pathways
Scientists reviewed 80 studies and found that certain bacteria can break down microplastics—tiny plastic particles polluting our water—by "eating" them with special enzymes. The bacteria work best on some plastics like PET (used in water bottles), breaking down up to 50% in just days, but struggle with tougher plastics like grocery bags. While this bacterial cleanup shows promise for reducing plastic pollution that can enter our food chain, it currently only works well in controlled lab settings, not in real oceans and rivers.
