Abstract

Lactic acid is used in various industrial areas such as the food, pharmaceutical, textile and other chemical industries. In this study, 49 lactic acid bacteria were isolated from oral microbiota of voluntary patients. These isolates were screened for their lactic acid production abilities. The isolate which has a high potential for lactic acid production was selected. The optimal conditions for lactic acid production by Lactobacillus brevis were determined. According to the results obtained, sucrose as carbon source, 50 g/L of sucrose amount, diammonium hydrogen citrate as nitrogen source, 8 g/L of nitrogen amount, 42 °C as temperature, 4.5 x 108 CFU/mL of inoculum amount and 72 hours of incubation time were found to be optimal values.
从口腔微生物群中分离的短乳杆菌产乳酸
乳酸被用于各种工业领域,如食品、制药、纺织和其他化学工业。本研究从自愿患者口腔菌群中分离出49株乳酸菌。对这些分离株进行乳酸生成能力筛选。选择了产乳酸潜力大的分离物。确定了短乳杆菌产乳酸的最佳条件。结果表明,以蔗糖为碳源,蔗糖用量为50 g/L,柠檬酸氢二铵为氮源,氮用量为8 g/L,温度为42℃,接种量为4.5 × 108 CFU/mL,培养时间为72 h为最佳。
