摘　　要：对固态发酵赖氨酸的影响因素进行考察 ,在优化条件下 30℃发酵 96h产酸率 1.5 2g/ 10 0g干基 ,转化率2 5 .3% 。The factors impacting the solid-state fermentation of lysine were studied. 1.52 g lysine /100 g dry matter and 25.3% conversion rate were obtained under the optmal conditions of 30 ℃ temperature and 96 hours of fermentation period. This would have directive effects on preparing the high protein feed with enriched lysine and necessary amino acid from yeast and lysine strain mixtures through solid-state fermentation.
