产胞外多糖植物乳杆菌的筛选及粗多糖的活性研究
Screening of Exopolysaccharide (EPS)-Producing Lactobacillus plantarum and Bioactivity of the EPS
摘要
Abstract
The present study describes the screening of lactic acid bacterial (LAB) strains with high exopolysaccharide (EPS)-producing ability by observing whether they could form sticky colonies. One strain named AR307 was finally obtained and identified as Lactobacillus plantarum. In order to enhance EPS yield, the fermentation conditions for producing EPS by Lactobacillus plantarum AR307 were optimized. The yield of EPS produced by AR307 reached up to 389 mg/L after 20 h fermentation at 32 ℃. In vitro assay showed that the EPS had good inhibitory activity against colon cancer HT-29 cells and possessed an antidiabetic effect.关键词
