[Microbial Ecology in the Mask-derived Plastisphere in a Water Environment].

Researchers studied the microbial ecology of plastisphere communities forming on different layers of discarded face masks in aquatic environments over time. Each mask layer harbored a unique microbial community with increasing richness over time; functional analysis revealed pathogenic, phototrophic, and compound-degrading capabilities, as well as roles in carbon and nitrogen cycling, indicating ecological significance of mask-derived plastisphere.

Potential of Freshwater Microalgae in Biodegradation of Disposable Face Masks

Researchers investigated whether freshwater microalgae could biodegrade disposable face masks — a major source of pandemic plastic waste — measuring plastic weight loss and surface degradation under algal cultures. Selected algal species showed measurable degradation of mask fibers, suggesting a biological treatment pathway.

Biotransformation of microplastics from three-layer face masks by nitrifying-denitrifying consortia

Lab experiments showed that microorganisms performing nitrogen cycling (nitrification and denitrification) can chemically alter the surface of polypropylene microplastics shed from COVID-era disposable face masks. The biological changes to the plastic surface may increase its ability to adsorb other contaminants or alter how long it persists in the environment, raising new questions about what happens to the surge of pandemic-era plastic waste in wastewater systems.

Microbial degradation of polypropylene microplastics and concomitant polyhydroxybutyrate production: An integrated bioremediation approach with metagenomic insights

Researchers isolated microbial consortia capable of degrading polypropylene microplastics, achieving weight losses of up to 17.8% after 30 days of incubation. The most effective consortium also produced polyhydroxybutyrate, a biodegradable plastic alternative, while breaking down the polypropylene. Metagenomic analysis revealed abundant carbohydrate-active enzymes and oxidation pathways, suggesting an integrated bioremediation approach that simultaneously degrades plastic waste and generates a useful bioplastic.

Plastic-Degrading Microbial Consortia from a Wastewater Treatment Plant

Researchers isolated bacteria from a wastewater treatment plant that can break down common plastics including polyethylene and polystyrene, some of the hardest plastics to recycle. The microbial communities worked together to degrade the plastics more effectively than individual bacterial strains. While biological plastic degradation is still slow compared to the scale of pollution, identifying these bacteria is a step toward developing biotechnology solutions for plastic waste cleanup.

Synergistic functional activity of a landfill microbial consortium in a microplastic-enriched environment

Scientists studied soil bacteria from a decades-old landfill to understand how microbes adapt to high concentrations of polyethylene and PET microplastics. They found that multiple bacterial species work together to break down these plastics, with different roles for bacteria floating freely versus those attached to plastic surfaces. While biodegradation of microplastics is possible, it is slow, and understanding these natural processes could eventually help with cleanup efforts.
