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.野生与突变型混淆魏斯氏菌（Weissella confusa）所产胞外多糖（exopolysaccharide, EPS）的表征、抗氧化及免疫调节潜力。相较于突变菌株，野生混淆魏斯氏菌所产胞外多糖（WWCEPS）产量最高。该类胞外多糖中共含有8种单糖，其中半乳糖（Galactose）在野生混淆魏斯氏菌胞外多糖（WWCEPS）与突变型混淆魏斯氏菌胞外多糖（MWCEPS）中占比最高，含量分别为34.60196 mg/100g与33.47168 mg/100g EPS。野生与突变型混淆魏斯氏菌胞外多糖均具备抗氧化活性：WWCEPS的1,1-二苯基-2-三硝基苯肼自由基（DPPH）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高，分别达71%、1.88%、86.7%与1.85%。野生及突变型混淆魏斯氏菌胞外多糖对受试小鼠均具有免疫调节活性。
