Probiotics: A New Concept In Prophylaxis
Abstract: Foods that have health benefits beyond the traditional nutrients possessed by them are called functional foods or nutraceuticals. These are generally characterized as foods similar in appearance to conventional foods, consumed as part of usual diets and elicit health benefits beyond meeting the basic nutritional requirements. Functional foods reduce risk of diseases but they do not act as a vehicle to address deficiency. They are a source of mental and …

Isolation of Lactobacilli sp. from Various Nondiary Substrates—A Review
Abstract: Lactic acid bacteria (LAB) have also been delineated as bioprotective agents. Efficient pathogens’ inhibition has been derived by LAB. LAB competes with the microbes by modifying the microenvironment with their metabolic end products. The habitat of Lactobacilli is not only confined to diary but it has spread and adapted habitat to nondiary substrates too. This paper garners information about the various nonsubstrate habitats in which Lactobacilli can be isolated. Keywords: …
