Phenyllactic acid exposure suppresses Microcystis aeruginosa growth with concurrent PSII photochemical impairment and increased extracellular microcystin accumulation.
Phenyllactic acid (PLA) has been reported as a bioactive organic acid with anticyanobacterial potential, but its direct ecotoxicological effects on toxin-producing Microcystis aeruginosa remain insufficiently understood. In this study, purified PLA was used to evaluate its effects on the growth, photosynthetic physiolo...
