Aspergillus niger was investigated for its potential to degrade low-density polyethylene (LDPE) plastic in aquatic environments. Water samples from ocean, lake, pond, and river sources in West Bengal, India, were analyzed for physical parameters (pH, TDS, conductivity, turbidity) and screened for fungal presence. A. niger was isolated from 8 of 36 colonies across seven samples and identified macroscopically (jet-black colonies) and microscopically (conidial heads, septate hyphae). LDPE sheets (2×2 cm) were pretreated (ethanol wash, UV sterilization), immersed in A. niger contaminated water, and incubated at 28°C for 30 days. Weight loss measurements revealed progressive degradation, averaging 15% mass reduction (0.00471 g) after 30 days. Optimal degradation occurred in pond samples (29% weight loss), while ocean and river samples showed 11–18% and 10% degradation, respectively. The study confirms A. niger role as a potent plastic-degrading fungus in diverse aquatic habitats, supporting its use in bioremediation strategies.
