ClearDetermination of Biodegradation Potential of Aspergillus niger, Candida albicans, and Acremonium sclerotigenum on Polyethylene, Polyethylene Terephthalate, and Polystyrene Microplastics
Researchers tested the ability of three fungal species to biodegrade polyethylene, polyethylene terephthalate, and polystyrene microplastics over 30 days. Aspergillus niger showed the strongest degradation of polyethylene with 16% weight loss, while other fungi performed better on different plastic types. The study demonstrates that fungal biodegradation is a promising approach for breaking down common microplastics, as confirmed by visible surface changes and chemical alterations in the treated plastics.

Wood decay fungi show enhanced biodeterioration of low-density polyethylene in the absence of wood in culture media
Wood decay fungi normally digest cellulose and lignin, but this study found that when wood is absent, these fungi dramatically increase their degradation of low-density polyethylene (LDPE) plastic — one fungal species achieved nearly 24% weight loss in just 45 days. This shows that fungi can adapt to use plastic as a carbon source, offering a potential biological tool for breaking down plastic waste and reducing microplastic formation in the environment.

Biodegradation of Plastics by Fungi
This review examines how fungi — including naturally occurring species found in soil and marine environments — can break down common plastic polymers including polyethylene under low-nutrient conditions.

Scaling up fungal biodegradation remains a challenge, but the findings suggest microbes could play a significant role in reducing environmental microplastic accumulation over time.
