Harmful algal blooms (HABs) commonly cause significant damage to aquatic systems due to toxin production and depletion of oxygen. In this study, the low molecular weight water-soluble chitosan (LMWSC) was investigated as a new algicidal compound by first investigating the potential of LMWSC in selective combating HABs. The LMWSCs disrupted algal cell and chloroplast membranes within 1 h against HABs, leading to efflux of the intracellular components. For co-cultivation of harmful and harmless algal, LMWSC selectively kill the harmful algal. Based on these results, LMWSC is a promising novel material for harmful algal bloom control.
