Research progress on the biological control of cyanobacterial blooms

Water eutrophication can cause cyanobacteria blooms, which seriously affects the health of water ecosystem and threatens the safety of drinking water. Eutrophication and cyanobacteria blooms are one of the difficult problems in lake water pollution control in China. Generally, there are physical method, chemical method and biological method in control cyanobacterial blooms. In recent years, biological method has gradually attracted the attention of scholars at home and abroad due to their economically-feasible and environment-friendly characteristics. In this study, the biological control of cyanobacterial blooms using microbial method, plant method, and animal method were reviewed. The action mechanisms, application advantages and existing problems of every method were reviewed. At last, several aspects that need to be further studied were proposed.
