A <i>Bacillus subtilis</i> strain with efficient algaecide of <i>Microcystis aeruginosa</i> and degradation of microcystins.

ABSTRACT: Global concerns over harmful cyanobacterial blooms brought on by eutrophication are now widespread. Aquatic ecological restoration techniques that use algicidal bacteria to control toxic algae show promise. A Bacillus subtilis S4 (S4) strain with strong Microcystis aeruginosa algicidal activity and the capacity to degrade microcystins (MCs) were successfully isolated and evaluated in this study. The dynamics of internal and extracellular MC concentration as well as the physiological response and morphological properties of M. aeruginosa were investigated in the M. aeruginosa/bacteria co-culture system. The findings demonstrated that when S4 density grew from 1 × 10⁶ cells/ml to 1 × 10⁸ cells/ml, the release of M. aeruginosa lysis and
