Clearly, the Leuconostoc reference strains of this study (many of which were present in a single cluster) appeared more homogeneous than the Lactobacillus reference strains, which were widely scattered, on the basis of CFA content. Leuconostoc citreum (DSM 20188) and
Leuconostoc factis (DSM 20202) differed widely on the basis of CFA profiles from all other Leuconostoc reference strains, but appeared closely related to each other.
