    食源性凝结芽孢杆菌的筛选及其降血糖、血脂功能评价

    Screening of food-borne Bacillus coagulans and preliminary evaluation of its hypoglycemic and hypolipidemic functions

    • 摘要: 凝结芽孢杆菌(Bacillus coagulans)是益生菌,为了获得具有较强降血糖、血脂潜力的优质菌株,采用平板划线、形态学鉴定和16S rDNA鉴定相结合的方法,从传统发酵食品中分离出6株凝结芽孢杆菌,并对其产酸能力、抗氧化能力(DPPH自由基清除率、羟自由基清除率和还原力)、α-葡萄糖苷酶抑制率及胆酸盐结合能力进行了分析。结果表明:C3.3的产酸能力最强,发酵24 h后pH可达4.53;T1.2菌悬液的DPPH清除率、羟自由基清除率和还原力分别为24.60%、94.94%和 0.37;E4.2和T1.2的α-葡萄糖苷酶抑制率为86.50%和79.00%,显著高于其他菌株;T1.2菌悬液和发酵液的甘氨胆酸钠结合率均显著高于其他菌株,可达86.85%和68.25%,T1.2菌悬液的牛磺胆酸钠结合能力可达85.64%,另外发现6株菌的菌悬液的胆酸盐结合能力普遍高于发酵液。T1.2菌悬液和发酵液的抗氧化能力、α-葡萄糖苷酶抑制率以及胆酸盐结合能力均显著高于其他5株菌。T1.2是具有较强降血糖、血脂潜力的优质菌株。本研究可为开发辅助治疗高血糖、高脂血症的凝结芽孢杆菌提供理论依据。

       

      Abstract: Bacillus coagulans is a probiotic that produces lactic acid, which has become an important research focus in recent years because of its high persistence. In this study, six strains of Bacillus coagulans were isolated from conventional fermented food through plate delineation, morphological characterization and 16S rDNA identification. The acid production, antioxidant capacity (DPPH· clearance rate, OH· clearance rate and reduction capacity), α-glucosidase inhibition and bile-acid salt binding capacity were also analyzed. The results showed that all six strains of Bacillus coagulans had strong acid production ability, and C3.3 had the strongest acid production ability, with pH up to 4.53 at 24 h. The DPPH· clearance rate, OH· clearance rate and reduction capacity of T1.2 suspension were 24.60%, 94.94% and 0.37, which were significantly higher than those of other strains. E4.2 and T1.2 showed significantly higher α-glucosidase inhibition rates of 86.50% and 79.00% than the other strains. The binding capacities of sodium glycylcholate in T1.2 suspension and fermentation broth were significantly higher than those of other strains, which reached 86.85% and 68.25%. The binding capacities of T1.2 suspensions of sodium taurocholate could reach 85.64%. Moreover, bile-acid salt binding capacities of the suspensions of the six strains was generally higher than those of the fermentation broth. In conclusion, the antioxidant capacity, α-glucosidase inhibition rate and bile-acid salt binding capacity of T1.2 were significantly higher than those of the other five strains. This study provides a theoretical basis for the development of Bacillus coagulans for the adjuvant treatment of hyperglycemia and hyperlipidemia.
