L.A.B is the abbreviation for Lactic Acid Bacteria. L.A.B’s are gram-positive, acid-tolerant bacteria which are generally found in milk products and certain decomposing plants. These bacteria produce lactic acid as the end product of carbohydrate fermentation.
Anatomically, most lactic acid bacteria are spherical or rod-shaped. They are also able to thrive in environments with relatively low pH range. L.A.Bs have found commercial applications in probiotics, which are aimed at introducing live, beneficial microbes in the human gut. Most of the strains of bacteria used in probiotics belong to the genus Lactobacillus.
