Data for: Characterization, antioxidant and immunomodulatory potential on exopolysaccharide produced by wild and mutant Weissella confusa strains

characterization, antioxidant and immunomodulatory potential of exopolysaccharide (EPS) produced by wild and mutant Weissella confusa. Wild Weissella confusa (WWCEPS) produced the highest EPS compare to the mutant strain. Eight (8) monosaccharides were present in the EPS. Galactose had the highest composition (34.60196 mg/100g and 33.47168 mg/100g EPS) in WWCEPS and mutant Weissella confusa EPS (MWCEPS). WWC and MWC EPS had antioxidant capacity. WWCEPS had the highest DPPH capacity, total antioxidant activity, hydrogen peroxide and reducing power activity (71%, 1.88%, 86.7% and 1.85%). Wild and mutant Weissella confusa EPS had immunomodulatory activity on the treated mice.

本研究针对野生与突变型混乱魏斯氏菌（Weissella confusa）所产胞外多糖（exopolysaccharide, EPS）的表征、抗氧化及免疫调节活性潜力展开分析。相较于突变菌株，野生型混乱魏斯氏菌所产胞外多糖（WWCEPS）的产量最高。该类胞外多糖共包含8种单糖；在WWCEPS与突变型混乱魏斯氏菌所产胞外多糖（MWCEPS）中，半乳糖的含量最高，分别为34.60196 mg/100g EPS与33.47168 mg/100g EPS。野生与突变型混乱魏斯氏菌所产的胞外多糖均具备抗氧化活性，其中WWCEPS的DPPH自由基清除能力、总抗氧化活性、过氧化氢清除能力与还原力活性均为最优，对应数值分别为71%、1.88%、86.7%与1.85%。野生与突变型混乱魏斯氏菌所产胞外多糖对受试小鼠均具有免疫调节活性。
