Microcystis aeruginosa is a prevalent cyanobacterium linked to water eutrophication and harmful algal blooms.

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.

Abstract Cyanobacteria bloom and the secondary metabolites released by microorganism are extremely harmful to aquatic animals, yet study on their adverse effects in zoobenthos is rare. Corbicula fluminea widely distributed freshwater environment with algal blooms. It a typical filter feeding that may be affected of cyanobacteria due its high filtering rate. In this study, C. was exposed Microcystis aeruginosa exudates (MaE) for 96 h, which obtained from 5 × 10 cells/mL 2.5 6 exponential stage M. culture solution represented cell density needs environmental risk precaution control emergent control, respectively. The responses critical organs MaE were analyzed evaluated based histopathological sections, antitoxicity biomarkers, organ function biomarkers. results showed all underwent structural disorders, vacuolization, apoptosis, necrosis, damage levels increased as concentration increased. detoxification antioxidant defense systems biomarkers each response exposure differently level reaction improved when siphon rate acetylcholinesterase activity filtration decreased significantly Increased glutathione S-transferase amylase digestive gland indicate it major . vitellogenin enlarged oocytes gonad have an estrogenic effect This demonstrates threat benthic bivalves inducing oxidative stress, inhibiting system, disturbing digestion system reproduction potential
