Abstract

Abstract: The growth promoting effect of the supernatant of fermented skim milk with Paenibacillus spp. BD3526 on Lactobacillus plantarum ST-Ⅲ inoculated into skim milk was analyzed in this study. The results showed that the supernatant of BD3526 cultured in skim milk for 5–9 d significantly promoted the growth of ST-Ⅲ in skim milk and exhibited high milkclotting activity. After ST-Ⅲ was cultured in skim milk added with the supernatant of BD3526 for 24 h, the pH value decreased from 6.44 to 4.70–5.08, and milk clotting was observed at 16 h along with a viable cell count of 9.22–9.35(lg(CFU/mL)).

Key words: fermented supernatant; proteolysis; Lactobacillus plantarum ST-Ⅲ

摘要： 研究类芽孢杆菌BD3526脱脂乳发酵上清对植物乳杆菌ST-Ⅲ在脱脂乳中的生长影响.结果表明:培养5～9 d的BD3526脱脂乳发酵上清液可显著促进植物乳杆菌ST-Ⅲ在脱脂乳中的生长和凝乳.与空白对照相比,添加含5～9 d发酵上清的脱脂乳培养24 h后,pH值从6.44降至4.70～5.08,16h发生凝乳,活菌数达到9.22～9.35 (lg (CFU/mL》).
