PURPOSE: A composition containing a certain algicidal bacteria for controlling harmful algae is provided to suppress abnormal proliferation of the harmful algae and to prevent damage due to the harmful algae and water pollution. CONSTITUTION: Lactobacillus sp. or Lactococcus sp. algicidal bacteria are used for controlling proliferation of harmful algae. The harmful algae cause water bloom. A composition for controlling the harmful algae contains the algicidal bacteria or a material derived from the algicidal bacteria. The material derived from algicidal bacteria is prepared from a petroleum ether, diethyl ether, chloroform ethyl acetate, or N-butanol fraction of the algicidal bacteria. A method for controlling harmful algae comprises a step of treating the composition to an area where the harmful algae exist. |
