Microcystis aeruginosa is a prevalent cyanobacterium linked to water eutrophication and harmful algal blooms. While bacterial control strategies are well-studied, the effects of white rot fungi on less understood. This study examines impact whole fungal liquid, its centrifuged supernatant, sterilized solutions algae's physiological biochemical traits. Metabolomics multivariate analysis identified significant changes in 47 metabolic markers, including carbohydrates, amino acids, fatty across treatments. The complete liquid exhibited strongest algicidal effect, likely due synergistic solubilization mechanisms mediated by extracellular enzymes such as manganese peroxidase, catalase, laccase. Notably, activity persisted even after sterilization, suggesting presence non-proteinaceous compounds like polysaccharides or lipids. disturbances included downregulation TCA cycle reduced acid synthesis, leading inhibited photosynthesis compromised nucleic integrity cells. research enhances our understanding how disrupt metabolism, providing theoretical basis for their potential use bioremediation eutrophic aquatic environments.
