纳豆芽孢杆菌的相关研究进展

Related Progress of Research of Bacillus Natto

纳豆芽孢杆菌是一种好氧型革兰氏阳性益生菌,具有较强的热、酸碱稳定性,进入肠道后迅速发育成营养性细胞,抑制肠杆菌、肠球菌、致病菌等的生殖,促进双歧杆菌、乳酸杆菌和梭菌等厌氧菌的生长,调节微生态平衡,代谢分泌出多种促进营养物质消化吸收的酶类,强化消化机能,同时刺激机体内的免疫系统产生干扰素等抗菌物质和高强溶栓功效的纳豆激酶,增强动物细胞免疫功能.纳豆芽孢杆菌可作为天燃防腐剂、微生态制剂、饲料添加剂、酶活性增强剂、免疫增强剂,提高食品的保藏期、动物的日增重和产奶率,运用到水体中可起到净化水质、改良底质等的作用.本文对纳豆芽孢杆菌的菌落结构、生长曲线、发酵产物及其功能应用进行综述,为充分发挥纳豆芽孢杆菌的功能,生产新型绿色国民生活所需品,降低生产成本提供理论支撑.

Bacillus natto is an aerobic Gram-positive probiotic,with a strong themal and pH stability,that can rapidly tranform into nutritional cells in the intestine.The reproductive of some colonies is inhibited,for example E.coli,Enterococci and Bacteria,the growth of anaerobic bacteria is promoted.Bifidobacterium,Lactobacillus and Clostridium can regulates the microecological balance.The metabolism of Bacillus natto can secrete avariety of enzymeson to promote the digestion and absorption of nutrients,strengthing digestive function,stimulating the body＇s immune system to produce antimicrobial substances and high-strength thrombolytical nattokinase,enhancing immune function of animal cells.Bacillus natto can be used as a preservative burning days,probiotics,feed additives,enzyme activity enhancers,immune enhancer,because it is able to improve food storage period,the rate of weight gain and milk production of animals,water purification and sediment.
