Abstract

A total of 31 strains of were subjected to DNA-DNA hybridization and were characterized by performing physiological tests and by performing a multilocus enzyme analysis, using malate dehydrogenase and glutamate dehydrogenase. All of the strains assigned to fermented glucose and sucrose, hydrolyzed starch but not esculin, and produced indole, acetic, isobutyric, isovaleric, and succinic acids as metabolic end products. The results of DNA reassociation experiments performed with the reference probe permitted separation of the strains into two well-defined homology groups. In addition, strains with DNAs that hybridized with DNA from strain ATCC 25611 (T = type strain) had high levels of peptidase activity and cleaved lipid substrates (4-methylumbelliferyl laurate and 4-methylumbellifelyl elaidate). Multilocus enzyme electrophoresis revealed two electromorphic profiles, one characteristic of strain ATCC 25611 and the other characteristic of strain ATCC 33563. We propose that a new species, , should be created for the genetically distinct group of strains that hybridized with strain ATCC 33563. Strain ATCC 33563 is designated the type strain of
