This finding substantiates that consumption of Lactobacillus rhamnosus can augment the general function of immune system. Moreover, it is useful as natural preservatives in yogurt-based foods and dairy products.
Lactobacillus rhamnosus produce exclusively L-lactic acid where investigation of lactic acid fermentation kinetics resulted the highest productivity that obtain lactic acid concentration higher than 85g/L using glucose substrate. This species are most extensively studied due to have various abilities as a good source of probiotics that promotes to maintain a healthy digestive tract in human though it has been associated with a very rare side effect.
