Deoxyribonucleic Acid Homologies Among Coryneform Bacteria

Abstract

The deoxyribonucleic acid homologies among 33 strains of coryneform bacteria with various cell wall types reflected the previous grouping of these organisms by Yamada and Komagata on the bases of the mode of cell division, principal amino acids in the cell wall, and the base composition of deoxyribonucleic acid. In addition, the following four homology clusters were found: (i) six strains of corynebacteria with a glycolyl type of cell wall, (ii) four strains of glutamic acid-producing bacteria, (iii) two strains of Brevibacterium linens, and (iv) three strains of coryneform bacteria containing LL-diaminopimelic acid in the cell wall.
