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5～9d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5～9d发酵上清的脱脂乳培养24h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（1g（CFU／mL））。
The growth promoting effect of the supernatant of fermented skim milk with Paenibacillus spp. BD3526 on Lactobacillus plantarum ST-Ill inoculated into skim milk was analyzed in this study. The results showed that the supematant of BD3526 cultured in skim milk for 5-9 d significantly promoted the growth of ST-Ⅲ in skim milk and exhibited high milk- clotting activity. After ST-Ⅲ was cultured in skim milk added with the supematant 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））.
