Pseudomonas Stutzeri may alter the environmental fate of polystyrene nanoplastics by trapping them with increasing extracellular polymers
AI summary Read the abstract
Researchers found that the denitrifying bacterium Pseudomonas stutzeri physically traps polystyrene nanoplastics within secreted extracellular polymers, which impairs bacterial growth and nitrogen removal gene expression while altering the particles' environmental fate and dispersal.
Effects of copper ions and their combination with nanoplastics on the aerobic denitrifying bacterium Pseudomonas stutzeri: denitrification performance, physiological and biochemical responses, and transcriptomic changes
AI summary Read the abstract
Researchers found that polystyrene nanoplastics mitigate copper ion toxicity in the aerobic denitrifying bacterium Pseudomonas stutzeri by enhancing extracellular polymeric substance secretion and upregulating nitrogen metabolism genes, with transcriptomic analysis revealing the mechanistic basis for improved denitrification performance under combined copper-nanoplastic stress.
Distinct responses of Pseudomonas aeruginosa PAO1 exposed to different levels of polystyrene nanoplastics
AI summary Read the abstract
Researchers examined the molecular mechanisms by which polystyrene nanoplastics affect Pseudomonas aeruginosa, finding dose-dependent responses in growth, metabolism, and virulence gene expression that reveal how nanoplastics interact with environmentally relevant bacteria.
Mechanistic insights into the impact of multi-dimensional microplastic stress on nitrogen removal by heterotrophic nitrifying-aerobic denitrifying bacteria: A meta-transcriptomic analysis
AI summary Read the abstract
Researchers studied how different types of microplastics affect bacteria that are used to remove nitrogen from wastewater. They found that PVC microplastics were particularly disruptive, interfering with enzyme function and gene expression needed for denitrification. The study provides molecular-level insights into how microplastic pollution could undermine biological wastewater treatment systems.
Effects of unmodified and amine-functionalized polystyrene nanoplastics on nitrogen removal by Pseudomonas stutzeri: strain characteristics, extracellular polymers, and transcriptomics
AI summary Read the abstract
Researchers investigated how two types of polystyrene nanoplastics — plain and amine-modified — affect the ability of bacteria to remove nitrogen from water, a process important for wastewater treatment. The amine-coated nanoplastics were found to be more disruptive than unmodified ones, altering the bacteria's cell surface, extracellular proteins, and gene expression. This matters because nanoplastics entering wastewater systems could undermine the biological processes that keep treated water safe to release into the environment.
