摘要
研究通过正交试验,确定了植物乳杆菌UR-3液体发酵饲料的最佳发酵工艺组合条件为:发酵时间48 h、接种量2.5%、温度37℃。在此条件下,植物乳杆菌液体发酵饲料粗蛋白含量显著高于未发酵饲料(P<0.05),粗蛋白含量由发酵前6.28%提高到6.94%;液体发酵饲料乳酸菌数量和乳酸含量显著高于未发酵饲料(P<0.05),乳酸含量达到212.34 mmol/L,生物量为21.62×10^9 cfu/mL。
The experiment determined the optimal fermentation process combination conditions for Lactobacillus plantarum fermented liquid feed by orthogonal test. Under the optimum fermentation condition of fermentation time 48 h, inoculum 2.5% and temperature 37 ℃, the crude protein content of Lactobacillus plantarum fermented feed was significantly higher than that of unfermented feed(P<0.05). The crude protein content increased from 6.28% to 6.94%. The amount of lactic acid bacteria and lactic acid in fermented feed was significantly higher than that in unfermented feed(P<0.05). The lactic acid content reached 212.34 mmol/L, and the biomass was 21.62×10^9 cfu/mL.
