摘要: 本实验以糖化的黑豆为基质,对五株乳酸菌的发酵性能进行了测试,其中嗜酸乳杆菌产酸最高,产酸速率最快。确定了嗜酸乳杆菌(La)、植物乳杆菌(Lp)和两岐双岐杆菌(Bb)为最佳菌种组合,确定了最佳种间比,即La:Lp:Bb=2:1:1,大豆汁为促生长物质。

Abstract: The fermentative capacities of five lactic acid bacterial were studied by using saccharified black soybean.The production of lactic acid of Lactobacillus acidophilus(La for short)was the one with highest yield with quickest production rate.The best strain combination was Laerobacillus acidophilus(La),Lactobacillus plantarum(Lp)and Bifidobacterium bifidum(Bb).The optimum proportion of species was La:Lp:Bb= 2:1:1.Soya milk was promoting-growth substances.

Key words: black soybean, lactic acid bacteria, soya milk
