Abstract
SUMMARY: Seven strains of homofermentative Lactobacillus newly isolated from human sources were found to possess all of the usual phenotypic characters of Lactobacillus leichmannii. However, a subsequent comparative study of the electrophoretic mobilities of their lactic dehydrogenases showed that these seven newly isolated strains were markedly different from collection strains of L. leichmannii. Determination of the mean DNA base composition of a representative sample of the new isolates (36·1 ± 1·2 moles % G + C) clearly indicates that they cannot be considered as L. leichmannii (50·8 ± 0·5 moles % G + C). The newly isolated strains have been assigned to a new species, L. jensenii.
