Abstract Macrophyte extracts inhibit cyanobacteria growth, offering a sustainable solution for bloom control. The present study aimed to evaluate the response of Microcystis aeruginosa aqueous obtained from dried biomass Pistia stratiotes L. and Pontederia crassipes Mart. Solms. parameters analyzed were cyanobacterial photosynthesis, generation reactive oxygen species, antioxidative response. chemical profile upon incubation was also analyzed. Both (4.0 g.L −1 ) inhibited growth in 6 days: 100% inhibition P. 60% . Photosynthetic activity inhibited: 99% 12% This related downregulation psbA gene (coding photosystem II protein D1). Exposure both increased concentration intracellular species cultures. Superoxide dismutase( SOD) enzymatic cultures exposed extracts. transcription sod not altered but peroxiredoxin ( prxA increased. Upon macrophyte with M. cultures, phenol concentrations decreased, their metabolic changed. Thus, extract outperformed inhibiting growth. plant dry allelopathic on can be used as alternative mitigate blooms. Practitioner Points Aqueous suppressed activity, while did not. elicited (ROS) production cells. Peroxiredoxin expression upregulated by exposure. superoxide dismutase (SOD)
