A recently published study in Microbial Cell Factories has reported the discovery of two bacterial strains capable of degrading PVC microplastics under laboratory conditions, contributing to the growing body of research into biological approaches for managing plastic waste.

Researchers isolated the bacteria from soil that had been exposed to plastic waste for more than a decade and found that a consortium comprising Stutzerimonas sp. NH2 and Glutamicibacter nicotinae NH27 achieved a 26.8% reduction in PVC microplastic mass over a 30-day test period. Multiple analytical techniques, including scanning electron microscopy, infrared spectroscopy and thermal analysis, confirmed changes to the structure and surface characteristics of the PVC particles following bacterial exposure.

Importantly, the authors note that this is the first reported evidence of PVC microplastic degradation by these bacterial species and that further work is required to understand the biochemical pathways and enzymes involved. While the research remains at an early stage and was conducted under controlled laboratory conditions, it highlights the increasing scientific interest in microbial technologies as a potential complement to conventional waste management and recycling strategies.

The findings contribute to a broader understanding of how naturally occurring microorganisms may interact with persistent plastic materials in the environment and point to promising directions for future bioremediation research.
