Abstract
SUMMARY: Thirty-one strains of heterofermentative lactobacilli have been examined by routine physiological tests, starch-gel electrophoresis of glucose-6-phosphate dehydrogenase and by qualitative analysis of cell wall amino acids. Two major subdivisions are apparent, corresponding to Lactobacillus fermenti with L. cellobiosus on one hand, and L. brevis with L. buchneri and L. viridescens on the other.
