Lactic acid producing fermentation has been known for thousands of years. Many different cultures used this method of food processing to improve the storage quality, palatability, and nutritive value of perishable foods such as milk, meat, fish and some vegetables. The micro-organisms that produce lactic acid are the lactic acid bacteria. In the literature the abbreviation LAB is frequently used. Today lactic acid bacteria are mainly associated with a group of dairy products such as cheese, yoghurt, kefir, and buttermilk. However lactic acid bacteria play an important role in bread production, are are used in technology of some meat products and preservation of vegetables. Lactic acid bacteria have been associated with beneficial health effects. There has been much interest in the use of various strains of lactic acid bacteria as probiotics, ie as viable preparations in foods or dietary supplements to improve the health of humans and animals. LAB have been used as probiotics to manage intestinal disorders such as lactose intolerance, acute gastroenteritis, constipation, and inflammatory bowel disease
