Micro-nanoplastics induce the physiological toxicity and metabolic disorder of Bacillus cereus DFH-1
AI summary
Researchers exposed the bacterium Bacillus cereus to micro- and nanoplastics of varying polymer types and sizes, finding that 150 nm PET nanoparticles caused the greatest harm—inhibiting early growth, deforming cell morphology, reducing antioxidant enzyme activity, and broadly disrupting metabolic pathways including the tricarboxylic acid cycle.

Analysing biotoxicity effects on Saccharomyces cerevisiae of nanoplastics and evaluating the biological effects using an integrated biomarker response index
AI summary Read the abstract
Exposure of Saccharomyces cerevisiae to three polystyrene nanoplastic variants (unmodified, carboxylated, aminated) paradoxically promoted yeast growth while simultaneously elevating oxidative stress biomarkers including ROS, MDA, and SOD, with aminated nanoplastics showing the greatest toxicity at all concentrations tested. The findings demonstrate that surface chemistry — not just concentration — determines nanoplastic toxicity, a key insight for modeling ecological and human health risks from nanoplastic pollution.
Microbial Nanobioremediation of Micro-Nanoplastics: Current Strategies, Challenges, and Future Prospects
AI summary Read the abstract
Researchers reviewed microbial nanobioremediation strategies — including bacterial biofilm formation, enzymatic degradation, and engineered microbial consortia — for breaking down micro- and nanoplastics in contaminated environments, while cataloging the significant challenges of slow degradation rates and toxicity to the remediating organisms. Developing effective biological cleanup methods is critical because micro- and nanoplastics are too small and widely distributed for mechanical collection, requiring in-situ solutions that work at the molecular level.
