Effects of WS Nanosheets on N-fixing Cyanobacteria: ROS overproduction, cell membrane damage, and cell metabolic reprogramming.

The ecotoxicity of tungsten disulfide (WS) nanomaterials remains unclear so far. Here, the toxicity of WS nanosheets on N-fixing cyanobacteria (Nostoc sphaeroides) was evaluated. Specifically, Nostoc were cultivated in media spiked with different concentrations of WS nanosheets (0, 0.

Toxicological effects of WS nanomaterials on rice plants and associated soil microbes.

As an important member of transition-metal dichalcogenides family, tungsten disulfides nanomaterials (WS NMs) have a wide range of applications. To date, their environmental risks remain largely unknown. In this study, rice plants were grown in soil amended with different concentrations (0, 10, and 100 mg/kg) of WS NMs for 4 weeks.

MoS Nanosheets-Cyanobacteria Interaction: Reprogrammed Carbon and Nitrogen Metabolism.

Fully understanding the environmental implications of engineered nanomaterials is crucial for their safe and sustainable use. Cyanobacteria, as the pioneers of the planet earth, play important roles in global carbon and nitrogen cycling. Here, we evaluated the biological effects of molybdenum disulfide (MoS) nanosheets on a N-fixation cyanobacteria () by monitoring growth and metabolome changes.
