NEWLY ISOLATED THRAUSTOCHYTRIUM SP. KJS-1, BACILLUS POLYFERMENTICUS KJS-2 AND FEED ADDITIVES FOR CULTIVATED FISH INCLUDING THRAUSTOCHYTRIUM SP. KJS-1, BACILLUS POLYFERMENTICUS KJS-2 AND BACILLUS LICHENIFORMIS, FEED CONTAINING ABOVE FEED ADDITIVES

摘要

Novel microorganisms producing DHA(docosahexanoic acid) are provided to improve quality of cultivated fishes by supplying DHA as an essential nutrient of fishes to fishes and inhibiting death of fishes, and clean the cultivation tank by inhibiting growth of fungi. The novel microorganisms producing DHA, Thraustochytrium sp. KJS-1(KCCM 10667P) and Bacillus polyfermenticus KJS-2(KCCM 10769P) are selected from microorganisms producing unsaturated fatty acid, isolated from the South coast region. The feed additives for cultivating fishes contain Thraustochytrium sp. KJS-1(KCCM 10667P) and Bacillus polyfermenticus KJS-2(KCCM 10769P), and Bacillus licheniformis.
