This paper summarizes the action mechanism and the physiological function . take lactobacillus for example , we illustrate the genetic modifying function of the probiotics , and make a prospect on it 摘要综述了益生菌的作用机理和生理功能，以乳酸菌为例介绍了益生菌的遗传修饰作用，并展望了益生菌的发展前景。
Probiotics can promote health and is widely used in food industry . this paper introduced its concept , research situation at home and broad , safety , necessary condition , and application in food industry 摘要益生菌能够促进人体健康，在食品工业中有广泛的应用。该文综述了益生菌的概念、国内外研究现状、安全性和必备条件及其在食品加工中的应用。
Probiotics contain live microorganisms , usually so - called good bacteria , that colonize the intestine . they are sold as supplements but also found naturally in many fermented food including yogurt and certain juices 微生物制剂含有活的微生物，通常称为益生菌，寄生于肠道。这类制剂作为营养补充剂销售，也存在于一些发酵食品，包括酸乳酪和罐装饮料。
This shortened detection protocol is validated for infant formula , its ingredients and environmental samples from milk powder factories . in addition , for matrices containing probiotic bacteria specific enrichment procedures are provided 短时检测方法应用于奶粉工厂婴儿配方粉及其原材料和环境样的检测.另外,对于含益生菌的产品,提供特殊的富增过程。
Moreover , the em mix is an optimized cultivated mixture of naturally occurring pro - biotic bacteria mainly consisting of lactic acid bacteria , yeast , photosynthetic bacteria , etc . this mix is good for the human body and contributes greatly to the health of the global environment too 而且抗氧化型有用微生物群主要最适合复合培养乳酸菌酵母菌光合成菌等天然益生菌,既有利于人体健康,也有利于保护地球环境。
Bacillus licheniformis ts - 01 separated by institute of animal science , china academy of agriculture science and identified by institute of microbiology , chinese academy of sciences , can be used as a strain of feed probiotics , whose effectiveness has already been proved by feed experiments 地衣芽孢杆菌ts - 01由中国农业科学院畜牧研究所分离，经中国科学院微生物研究所鉴定，可以用作饲用益生菌，其有效性已被饲喂实验所证明。
Ten potential probiotics stains were tested in this experiment . including two lactobacillus acidophilus strains fbi and a878 , two bifidobacteria strains pba and inf , four enterococcus strains ml , pb2 , a30 , a31 . one bacillus abticism2 , one clostridium butyricum strain was isolated from commercial probiotics by using tpy 本试验共测定9株潜在益生菌，其中pb1和a878为嗜酸乳杆菌； inf和pba为双歧杆菌； m1 、 pb2 、 a30 、 a31为链球菌； m2为枯草芽孢杆菌。
Most lactic acid bacteria ( lab ) are commonly considered as safe probiotics . some strains of lactic acid bacteria are found to have the ability to adhere and live in the gastro - intestinal tract , urinogenital system or mucosa with no contemporary immunogenicity . importance is widely attached to the research of the lab as live oral and mucosal vaccine 大部分乳酸菌是普遍认为安全的益生菌，利用一些乳酸菌可以在胃肠道、泌尿、生殖系统中或粘膜部位粘附存活且无病原性等特点，开展乳酸菌作为活菌口服疫苗或粘膜疫苗载体的研究受到了广泛的重视。
But four enterococcus grew quickly and hadn " t delaying period , the final period of logarithm growing of all tested strains were 12 hour for i acidophilus pb1 and a878 ; 24 hour for bifidobacteria pba and inf ; 8 - 10 hour for enterococcus ml , pb2 , a30 , a31 and bacillus abticism2 the growth inhibition of escherichia coli , shigellosis , salmonell by the fermented liquor of eight probiotics bacteria was tested 确定各菌株对数生长期末期分别为： pb1和a878 ： 12h ； inf和pba ： 24h ； pb2 、 m1 、 a30 、 a31 、 m2 ： 8 - 10h 。采用牛津杯法测定八种潜在益生菌对大肠杆菌、痢疾杆菌、沙门氏菌的抑制性，结果表明，嗜酸乳杆菌pb1 、 a878和双歧杆菌pba 、 inf具有较强的抑菌能力，对三种致病菌能够形成明显的抑菌圈，而且对三种致病菌的抑菌能力明显不同。
