Marine 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.

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.

Phenotypic and Genomic Characterization of Polyethylene-Degrading Bacillus cereus PE-1 Enriched from Landfill Microbial Consortium

Scientists found a bacteria called Bacillus cereus PE-1 in landfill soil that can actually eat and break down plastic bags and containers (polyethylene). The bacteria damaged the plastic's surface and reduced its weight by about 5% in just 30 days, suggesting it could potentially help clean up plastic pollution in the environment. While this research is still early and needs more testing, it offers hope for using natural bacteria to tackle the growing problem of plastic waste that threatens our ecosystems and food chain.

Identification of plastic-degrading bacteria in the human gut

Scientists discovered bacteria in the human gut that can break down common plastics like polyethylene and polypropylene, though all the plastic-degrading species identified were opportunistic pathogens. The bacteria could physically and chemically alter plastic surfaces but only achieved limited depolymerization. This finding raises the question of whether microplastic exposure in the gut could promote the growth of potentially harmful bacteria while they attempt to digest the plastic.
