PROBLEM TO BE SOLVED: To provide cyanophage capable of specifically infecting the water bloom-causing blue-green algae of the genus Microcystis and proliferating, to provide a method for controlling water bloom with the cyanophage, to provide an agent for controlling water bloom, to provide a method for isolating the cyanophage, to provide a method for concentrating/purifying, to provide a subculture method, and to provide a preservation method. SOLUTION: The cyanophage having a total length of 0.01 to 0.4μm and capable of specifically infecting the algae of the genus Microcystis and proliferating. The method for isolating the cyanophage includes a process for filtering a liquid sample containing the cyanophage with a filter, inoculating the obtained filtrate into a solution for culturing the algae of the genus Microcystis, culturing the cyanophage, and then subjecting the alga dissolution-observed culture solution to a limiting dilution treatment to clone the cyanophage. The agent for controlling water bloom contains the cyanophage as an active ingredient. The method for controlling water bloom comprises spraying the cyanophage on a water area. The method for concentrating/purifying the cyanophage, the subculture method, and the preservation method. COPYRIGHT: (C)2006,JPO&NCIPI
