Minimal Conditions to Degrade Low Density Polyethylene by Aspergillus terreus and niger
Summary
Researchers demonstrated that Aspergillus terreus and Aspergillus niger can degrade low-density polyethylene (LDPE) under minimal nutritional conditions using only LDPE and sucrose as carbon sources, achieving up to 30% weight loss without requiring co-substrates or photothermal pretreatment.
Plastics pollution is a major worldwide concern because there is strong evidence about marine influence on the human trophic chain. Thus, we experimented with the biodegradation of low density polyethylene (LDPE) by A. niger and A. terreus in order to increase the degradation rate without any co-substrate or photothermal treatment. Our contribution is to show how to degrade LDPE under minimum nutritional conditions using both LDPE and sucrose as carbon sources. Up to 30% weight loss was obtained by A. niger and A. terreus which were isolated from an Ecuadorian mangrove. The evidence of cracks and biomass growth on the LDPE surface samples showed the potential of both fungi species to operate under low nutrient concentrations. The outlook of the present work was focused on understanding the fungi survival under minimal conditions.

Biodegradation of Low-Density Polyethylene (LDPE) by Aspergillus niger
Researchers examined the ability of Aspergillus niger isolated from landfill soil to biodegrade low-density polyethylene (LDPE) under varying conditions of pH, temperature, and carbon and nitrogen sources.

Biodegradation potential of low-density polyethylene (LDPE) using Aspergillus niger and Phanerochaete chrysosporium
Researchers tested two common fungi — Aspergillus niger and Phanerochaete chrysosporium — on low-density polyethylene plastic and found they degraded up to 40% of the material in just 20 days. The findings suggest these fungi could be part of a biological strategy for breaking down one of the world's most common plastic types.
