LAB all have remarkable genetically encoded S3mthetic capabilities including the production of excreted bacteriocins together with immunity devices that render them insensitive to their own peptide-toxins. The secretion of these antimicrobial peptides is used by lactic acid bacteria for biological warfare and cell communication (Eijsink et al. 2002).

The LAB group is remarkably diverse in their habitats, which are well reflected by their metabolic and transport capabilities. These organisms include the closely related Lactobacillus easel and Lact. brevis, Pediococcuspentosaceus, as well as the more distant Lact. gasseri and Lact. delbrueckii which are often found in plants and their products as well as natural inhabitants of the human gut (Vaughan et al. 2002 Makarova et al. 2006 Lorca et al. 2007). These organisms are used by man for the fermentation of plant, dairy, and meat products. Two other LAB, Lactococcus lactis subspecies cremoris and Streptococcus thermophilus, distantly related to the other LAB but closely related to each other, are both found in milk and are useful for dairy product fermentations. Finally, two additional LAB, closely related to each other but more distantly related to the others, are Leuconostoc mesenteroides, useful for food fermentation purposes, and Oenococcus oeni, important in wine production (Hastings et al. 1991 Mills et al. 2005).
