Bacillussubtilis and application thereof in raising Apostichopus japonicus

Abstract

The invention relates to separation of Bacillussubtilis and application of the Bacillussubtilis in raising Apostichopus japonicus. The Bacillussubtilis can effectively inhibit vibriones and other pathogenic bacteria from breeding, and promote the growth of the Apostichopus japonicus. The strain is separated from gills of fished captured in the Dalian sea area, and is preserved by China General Microbiological Culture Collection Center with the collection number of CGMCC No.3498. The Bacillussubtilis can be widely applied to breeding and production links in the fishery industry, can degrade, convert and metabolize metabolic products in the breeding and production processes, creates good ecological environment, and improves, preserves and repairs the ecological environment of water resources to fulfill the aims of reducing self-pollution, reducing medicinal harm, reducing cost, lightening the pollution of the aquaculture to the whole ecological environment and improving the quality of cultured products.

Description

technical field [0001] The invention relates to the isolation of a strain of Bacillus subtilis and its use method in raising imitation sea cucumber seedlings. The strain can effectively inhibit the reproduction of pathogenic bacteria such as Vibrio in the seawater during the cultivation of aquatic organisms and can promote the growth of sea cucumber imitation sea cucumbers . Background technique [0002] At present, with the rapid development of high-density mariculture industry and the intensification of environmental pollution, the disease of farmed animals has become a major problem in the development of mariculture industry in my country and even the world. It is recognized that the disease prevention and control of farmed animals is controlled by drugs. Due to the use of antibiotics, the ecological environment of farmed animals is destroyed, the growth of farmed animals is inhibited, and food safety cannot be guaranteed. Therefore, the use of antibiotics is strictly lim...

Problems solved by technology

It is recognized that the disease prevention and control of farmed animals is controlled by drugs. Due to the use of antibiotics, the ecological environment of farmed animals is destroyed, the growth of farmed animals is inhibited, and food safety cannot be guaranteed. Therefore, the use of antibiotics is strictly restricted.
