Globally, the plastic pollution has become a major issue that poses a major threat to the soil ecosystem. Plastic degradation is a quite challenging process as plastic persists in the environment for longer durations causing harm to surrounding flora and fauna. Polyethylene is most abundantly found as a contaminant in the environment. It may enter the food chain causing harm to health. The dynamics of microplastic pollution in soils, as compared to aquatic environments, are nuanced and influenced by diverse factors, including sources, transport mechanisms, and interactions within the soil matrix. The prevalence of microplastic pollution in terrestrial systems, particularly soils, highlights the need for comprehensive research and management strategies to address this environmental issue. In response to these environmental challenges, research in nanoscience has gained momentum, particularly in the synthesis of nanoparticles. These nanometer-scale particles can be engineered to have various shapes, sizes, and degrees of uniformity, making them highly versatile for a wide range of applications like environmental remediation. In the current experimental study the synergetic action of Eisenia fetida and ZnO bacterial nanoparticles synthesized from Bacillus cereus showed promising result with context to LDPE microplastic degradation. LDPE Microplastic degradation was confirmed by FTIR and SEM analysis. Morphological changes like fractures on the polymer surface were observed in SEM, and changes in functional groups were reported in FTIR analysis. This opened new doors for more research with context to the bioremediation potential of earthworm species and their gut microflora through and eco- friendly approach.
