Optimization on Solid State Fermentation Conditions of Producing Polypeptide Feed from High-temperature Soybean Meal
摘要
Abstract
The optimal solid state fermentation conditions of polypeptide production feed with Bacillus subtilis from high-temperature soybean meal were studied in this paper. The effects of medium composition on the yield of polypeptide were studied respectively. The orthogonal experiment was designed to obtain optimal fermentation medium, which were soybean meal:wheat meal 2:1, adding 110％ water and 4％ molasses. The effects of fermentation factors on the yield of polypeptide were studied,respectively. The optimal solid state fermentation conditions obtained from response surface methodology were inoculated with 15％ of Bacillus subtilis and fermented at 34℃ for 72 h, the production rate of soybean polypeptides could reach 46.29％.关键词
