The present invention relates to a strain Bacillus megaterium PS352 ( Bacillus megaterium PS352), which is environmentally friendly and useful as an additive for animal feed, and a feed additive and a feed containing the strain as an active ingredient.n n n PS352 strain according to the present invention has a strong antimicrobial activity against various pathogenic microorganisms, and is resistant to various feed antibiotics. It is also resistant to bile acids and artificial gastric juices and can reliably survive a wide range of pH and heat. It also produces high titers of starch, protease, xylanase, pectinase, glucanase and phosphatase in solid fermentation.n n n Therefore, it is possible to obtain a cheap and excellent microbial preparation for feed by the strain according to the present invention. |
