Its fermentative properties and metabolic products make bacteria of the genus Lactobacillus They are among the first organisms used by man for food production. They are also used for their preservation, by inhibiting the invasion by other microorganisms that cause food-borne diseases. The genus Lactobacillus consists of a large and diverse spectrum of bacterial species, which in general are nonpathogenic and are considered part of Lactobacillus is a highly phylogenetically and metabolically diverse genus comprising more than 200 species. The genus Lactobacillus is a heterogeneous group of lactic acid bacteria (LAB) with important implications in food fermentation. Lactobacillus species generally maintain DNA with a low G + C content (approx. Bacteriocin-producing Lactobacillus plantarum LD4 was identified using biochemical and molecular techniques including 16S rDNA amplification, followed by sequencing. Some aerobic bacteria grow better under slightly reducing conditions being known as microaerophiles such as Lactobacillus and Campylobacter. The exploitation of Lb. L. Acidophilus, L. Plantarum, L. Casei, L. fermentum with restricted acidification properties that lower the pH The food industry is trying to find new applications that will change the traditional approach to waste products and make them co-products (Farca et al., 2017). Among food substances that help to maintain reducing conditions are the SH groups in meats and the ascorbic acid, as well as, reducing sugars in fruits and vegetables. These bacteria, also known as vinegar bacteria, cause significant spoilage in the wine industry but are necessary for vinegar production. To evaluate the discrimination capability, six type strains of Lactobacillus species and six additional L. brevis strains were Either as starter, as adjunct cultures, or as probiotics, Lactobacillus strains are used as food preservatives not only to prevent the development of food spoilage but also to Description. Optimal Result: 2 - 10 Units. MICs of vancomycin were high (>256 microg/mL) for all other species except Lactobacillus gasseri and Lactobacillus jensenii.
