植物乳植杆菌-30产胞外多糖的结构表征及降尿酸作用
Structural Characterization and Anti-hyperuricemic Activity of Exopolysaccharides Secreted by Lactiplantibacillus plantarum-30
摘要
Abstract
This study obtained a strain producing high yield of exopolysaccharide(EPS),which was identified as Lactiplantibacillus plantarum HZB-30.The strain produced 230.66 mg/L of EPS after fermentation for 28 h.The molecular mass of EPS produced by HZB-30 was 14 639 Da,which was composed of several monosaccharides,such as glucose(37.76%)and galactose(19.15%).The EPS had high inhibitory activity against xanthine oxidase(XO)with an inhibition rate of 80.2%.After in vitro simulated digestion,the digestibility of the EPS was 20.7%,and 43.3%of the initial xanthine oxidase inhibitory activity remained.In an HK-2 cell model of hyperuricemia,the EPS at 20-60 μg/mL effectively decreased the levels of tumor necrosis factor-α(TNF-α),interleukin-1β(IL-1β),IL-6,and IL-8 and inhibited the accumulation of uric acid.The findings from this study are both theoretically and practically important for the application of HZB-30-derived EPS to develop anti-hyperuricemic food products.关键词
