Microcystin LR (MC-LR) pollution is a serious threat to aquatic ecosystems and public health in China and is an environmental problem that urgently needs to be solved. However, few studies have investigated the anaerobic degradation pathway and related molecular biological mechanisms of MC-LR. In this study, a bacterium capable of degrading MC-LR with a degradation efficiency of 0.

The biodegradation of organic aromatic compounds in subsurface environments is often hindered by limited dissolved oxygen. While oxygen supplementation can enhance in situ biodegradation, it poses financial and technical challenges. This study explores introducing low-oxygen concentrations in anaerobic environments for efficient contaminant removal, particularly in scenarios where coexisting pollutants are present.

Acetaminophen (APAP), one of the most frequently used antipyretic and analgesic medications, has recently grown into a persistent organic contaminant of emerging concern due to its over-the-counter and widespread use. The excessive accumulation of APAP and its derivatives in various environmental matrices is threatening human health and the ecosystem. The complexity of APAP and its intermediates augments the need for adequate innovative and sustainable strategies for the remediation of contaminated environments.

Tobacco, being a globally cultivated crop, holds significant social and economic importance. Tobacco plants are susceptible to the adverse effects of heavy metals (HMs), particularly cadmium (Cd), which hinders root development, disrupts water balance, and impedes nutrient absorption. Higher concentrations of HMs, especially Cd, naturally accumulate in tobacco leaves due to complex interactions within the plant-soil continuum.
