Risk assessment of potential toxic elements (PTEs), microplastics (MPs) and microorganisms in groundwater around landfills is critical. Waste from landfills seeps into groundwater contaminating water quality, threatening groundwater safety, and negatively affecting the ecosystem. This study explored spatial and temporal changes in PTEs, MPs, and microorganisms in the groundwater around a closed landfill.

Exogenous nitrogen supplementation for the bioremediation of petroleum-contaminated soils is a widely adopted and effective environmentally friendly strategy. However, the mechanism by which varying nitrogen dosages affect hydrocarbon degradation pathways remains unclear. This study conducted bioremediation on soil with a total petroleum hydrocarbon (TPH) content of 17,090 mg/kg over 210 days.

Background: Safe management of healthcare waste (HW) safeguards laboratory biosafety and biosecurity. Knowledge and attitudes influence HW practices, presenting a need for evidence of the current status.
Objective: This study assessed the knowledge, attitudes and practice of laboratory workers towards waste management at a regional hospital laboratory in Lesotho.
<b>Background and Objective:</b> Laccase as a ligninolytic enzyme has been known for its green-catalysis mechanism, which has the potential to be applied to food industries. Lignocellulose found in agro-industrial waste is promising for laccase production as a substrate, that could be encountered in pineapple (<i>Ananas comosus</i>) and Arabica coffee (<i>Coffea arabica</i>) industrial residue. To boost enzyme activity, laccase characterization was performed using <i>Ganoderma lucidum</i> under solid-state fermentation.

Microb Cell Fact
January 2025
State Key Laboratory of Pollution Control and Resource Reuse, College of Environmental Science and Engineering, Tongji University, Shanghai, 200092, PR China.
Background: The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization of resources from anaerobically digested sludge. White-rot fungi (WRF) have garnered significant research interest due to their exceptional capacity to degrade complex and recalcitrant organic pollutants.
