Bacillus strain having improved productivity of fermented soybean meal and method for producing fermented soybean meal using the same

摘要

The present invention provides Bacillus amyloliquefaciens K2G strain having excellent anti-nutritive factor removal activity, proteolytic enzyme activity and antibacterial activity against pathogenic bacteria, and having reduced mucus production ability, fermented soybean meal using the aforementioned strain The present invention relates to a production method, a fermented soybean meal produced therefrom, and a feed composition containing the same. Fermented soybean meal produced using the Bacillus amyloliquefaciens K2G strain according to the present invention is almost free from various anti-nutritive factors such as trypsin inhibitor, soybean oligosaccharide and polysaccharide, In addition to high solubility, it is composed of small-sized peptides that are easily digested and absorbed by livestock due to low molecular weight, and can be usefully used as a high-quality vegetable protein feed with excellent absorption rate and feed efficiency .
