Apostichopus japonicus Pseudomonas elyacovii HS1 strain and its use

Abstract

The invention discloses an Apostichopus japonicus Pseudomonas elyacovii HS1 strain (CCTCCM2012512), which belongs to Pseudomonas. With a strain code of HS1, the strain has a Latin scientific name of Pseudomonas elyacovii, and is preserved in China Center for Type Culture Collection (CCTCC) on December 6, 2012, with a preservation number of CCTCCM2012512. The strain can be used as a feed additive for Apostichopus japonicus. Being able to secrete protease, amylase and other digestive enzymes, the strain has the ability to promote digestive absorption of Apostichopus japonicas and can improve the growth performance of Apostichopus japonicas. The strain can survive in water without killing alga. Being able to proliferate substantially, the strain can compete with pathogenic bacteria in water for nutrition and decompose organic matters in water so as to play a water purifying role. Being a colonizable dominant strain in a real sense, the Apostichopus japonicus Pseudomonas elyacovii HS1 strain can replace chemical drugs to undergo disease prevention and control without destroying the ecological environment.
