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.
