Genus Lactobacillus
Beijerinck 1901
Gram-positive rods or coccobacilli, nonspore-forming; fermentative metabolism, obligately saccharoclastic, at least half
of end product carbon is lactate; facultatively anaerobic; gelatin not liquefied, indole and H
2S not produced, catalase
and oxidase negative; complex nutritional requirements for amino acids, peptides, nucleic acid derivatives, vitamins,
salts, fatty acids, and carbohydrates; growth temperature range 2–53 °C; optimal pH 5.5–6.2. Found in dairy products,
foods, beer, wine, fruits, water, soil, and sewage; they are a part of the normal flora in the mouth, intestinal tract, and
vagina of humans and many animals. Nonpathogenic or pathogenicity is restricted to persons with an underlying disease.
