Abstract

The invention relates to Arthrobacter CW9 (Arthrobacter sp. CW9) with CGMCC of No.4197. The bacterial strain is Gram positive bacteria without spore, capsule and motion. The colony on a 2216E flat possesses the characteristics of yellow, circle, intermediate protrusion, smoothness and moisture; The aerobic strain possesses optimum growth temperature of 26 DEG C and the optimum pH value of 7.6; the concentration for NaCl resistance is 10%, the optimum salinity is 1%, the growth can not generated without NaCl. The Arthrobacter CW9 can be used for raising the metamorphosis rate and survival rateof seawater crustaceans larvae. The bacterial strain screening method of the present invention is concise and high efficient, the Arthrobacter possesses probiotic function on the crustaceans larvae, the production method as well as the storage and transportation are simple, the application method is also simple; the Arthrobacter is employed only in crustaceans animal zoea one-stage, so that the metamorphosis rate of the post-larvae can be enhanced and stabilized, and the sprout seed output can be greatly increased.

Description

technical field

[0001] The invention relates to an aquatic probiotic Arthrobacter CW9 ( Arthrobacter sp. CW9) CGMCC No. 4197 (preserved in the General Microorganism Center CGMCC of China Microbiological Culture Collection Management Committee on October 8, 2010, and the preservation number is CGMCC No. 4197); the present invention also relates to the use of this strain. Background technique

[0002] In recent years, due to the aggravation of self-pollution of the aquaculture environment and the increasingly serious pollution of the natural environment, the living environment of farmed animals has continued to deteriorate, the number of pathogenic microorganisms has increased, and the speed of transmission has accelerated, causing major losses to the aquaculture industry. At the same time, the residues of certain prohibited chemicals used to prevent and treat diseases in animals have greatly affected the quality of products. However, due to the residues of prohibited dru...
