ALGICIDAL BACTERIA FOR THE PREVENTION OF ALGAL BLOOM

摘要

The present invention relates to algicidal bacteria among aerobic bacteria strains and random bacteria strains which can control algae exiting under water such as rivers. Particularly, the present invention relates to nature-friendly algicidal bacteria, capable of reducing and controlling generation of green algae, which can effectively control green algae, generated under water, before and after generation of the green algae. In order to innovatively control Microsystis sp. (particularity, Microsystis aeruginosa), which is a dominant species of blue-green algae, which generate green algal bloom, four strains Rhizobium sp, Aeromonas medis, Aeromonas caviae, and Stenotrophmonas maltophilia and six strains of Enterobacter sp., Arthrobacter sp., Comamonas sp., Enterobacter sp., Stenotrophomonas maltophilia, and Microbacterium sp. for effectively controlling Anabana Flos-aquae are selected to form a microorganism group. The strains are independently used or mixed appropriately for the purpose, are attached to the inside of a microspore (a piece of wood for example) which can provide a habitat or are sprayed to control green algal bloom. The strains can inhibit the growth of bacteria causing green algal bloom or can destroy the bacteria causing green algal bloom.
