Bacillus subtilis strain capable of killing algae and application thereof

Abstract

The invention discloses a bacillus subtilis strain capable of killing algae and application thereof. The strain is named (Bacillus subtilis) BLS1 and was collected in China Center for Type Culture Collection in Wuhan University on December 18, 2012, with a CCTCC No. of M2012534. The strain is capable of effectively killing harmful algae and has an obvious killing effect on microcystis aeruginosa which is most harmful to the body of fresh water so that algal bloom and red tide can be relieved and avoided in time. The application method of the strain disclosed by the invention is simple; the strain can be made into powder or tables according to a conventional method and can be put into the body of water anytime as required; in case of no red tide or algal bloom, the strain can be put into the body of water to balance floras in the body of water; the strain is safe to animals bred in the body of water, is mild in fermentation condition and can be put into culture enlargement easily.

Description

technical field [0001] The invention belongs to the field of microorganisms, in particular to a bacillus subtilis with algae-dissolving ability and its application. Background technique [0002] In marine and freshwater water bodies, due to the aggravation of eutrophication, excessive algal blooms or red tides form, which affect and change the physical and chemical properties of water bodies, and can directly or indirectly cause a large number of algae-eating animals to die. Traditional treatment methods, such as mechanical algae removal, high-frequency electromagnetic pulses, and the use of herbicides, are often limited by many factors such as cost and environmental safety issues. In contrast, biological algae control technology has low cost and good safety. Among them, algogenic bacteria have become a new direction for the prevention and control of algal blooms and red tides because of their high algae removal efficiency. [0003] Algae-lysing bacteria is a general term f...
