Abstract
Twenty strains of lactobacilli isolated from the stomach of conventional mice were tested for their ability to ferment or hydrolyze substrates that may be present in the stomach habitat. The lactobacilli could be placed in four groups (A to D) depending on their ability to ferment N-acetylglucosamine, dextrin, cellobiose, gum arabic, and xylan. The majority of the isolates belonged to groups A and D. Group A strains did not resemble previously described Lactobacillus species, but group D strains were identified as L. leichmannii. A representative group A isolate colonized the surface of the nonsecretory epithelium of the stomach of gnotobiotic mice; a group D isolate did not.
