益生菌在治疗和预防各种胃肠道疾病和保持身体健康方面是有用的。其关键机制是对抗各种疾病中产生的自由基。目前的项目工作重点是从牛奶中分离乳酸菌，并对其抗菌和抗氧化活性进行了评估。此外，还进行了测定聚集和粘附能力的最新方法。益生菌的这些特性在清除胃肠道病原体中起着重要作用。本工作首次对潜在益生菌的抗氧化、抗菌和聚集特性进行了综合研究。从乳制品样品、凝乳和奶酪中分离得到两个分离株。形态和生化测试表明，分离物1和分离物2可能分别为唾液l .和嗜酸l .。分离物1较分离物2具有更好的抗氧化、抗菌和体外粘附性能。在低pH、高NaCl、高蔗糖等不同条件下测定了菌株的活力。它们在不同条件下的生存能力与商业益生菌相当。 This signifies the importance of the isolates as potential probiotics.Molecular characterization of above-mentioned isolates needs to be done. There is a lot of scope of these studies in India as research in this field is in its infant stage. India is also one of the largest manufacturers of dairy products. So, considering these facts India has great potential in development of probiotics which provide various health benefits along with normal diet.
