Eutrophication is found to be one of the major issues worldwide. Freshwater as well as marine water bodies are affected due to rise in dominant harmful Algal Blooms (HABs) & depletion of oxygen in water. Cultural eutrophication enhances harmful effects of natural eutrophication causing various diseases due to bioaccumulation of toxins released by HABs in marine animals & seafood consuming human beings. Use of algicidal bacteria is one approach to restrict growth or lyse HABs in waterbodies. Commensal, mutualistic, parasitic relationships between species of algae & algicidal bacteria studied throughout the world. Variation in killing, resistance, regulation mechanisms found between algae & algicidal bacteria. Different isolation techniques of algicidal bacteria help to study different relationships among them. Algicidal effect of bacterial strain varies from species to species of different alga. Some of the HABs producing algal species are found to be of Alexandrium, Aphanizomenon, Chattonella, Cylindrospermopsis, Gymnodinium, Oscillatoria, Pseudo-nitzschia genus. The main objective of the review article is to study isolated algicidal bacteria found commonly in different countries.
