Biological and Chemical Bases for the Reclassification of Brevibacterium vitarumen (Bechdel et al.) Breed (Approved Lists, 1980) as Corynebacterium vitarumen (Bechdel et al.) comb. nov. and Brevibacterium liquefaciens Okabayashi and Masuo (Approved Lists, 1980) as Corynebacterium liquefaciens (Okabayashi and Masuo) comb. nov.

On the basis of their biological properties (cell morphology, staining reaction, cellular inclusions, guanine plus cytosine content of deoxyribonucleic acid, genome size, degree of deoxyribonucleic acid homology with Corynebacterium diphtheriae [Approved Lists, 1980] strain PW8, pattern of enzymic capacities) and chemical structures (peptidoglycan type, major cell wall polysaccharide, characteristic fatty acids, major phospholipids and glycolipids), two brevibacteria are transferred to the genus Corynebacterium. Brevibacterium vitarumen (Bechdel, Honeywell, Dutcher, and Knutsen) Breed (Approved Lists, 1980) is transferred as Corynebacterium vitarumen (Bechdel, Honeywell, Dutcher, and Knutsen) comb. nov., and Brevibacterium liquefaciens Okabayashi and Masuo (Approved Lists, 1980) is transferred as Corynebacterium liquefaciens (Okabayashi and Masuo) comb. nov.
