Conclusion 359 References 360 Abstract The term probiotics stands for bacterial strain acting for the uplift- ment of beneficial gut microflora as well as restricting the growth of decay or disease causing bacteria and other agents. They protect us from disease causing microorganisms and are vital for the diges- tion of nutrients and food.
