SUMMARY: The peptidoglycan of and contained lysine as the dibasic amino acid. In addition, glutamic acid and alanine were detected in the hydrolysates. Thin-layer chromatographic analysis of whole-organism methanolysates of and revealed the presence of single spots corresponding to simple non-hydroxylated fatty acid methyl esters. The major fatty acid structural types were straight-chain and monounsaturated acids. Menaquinones (vitamin K) were the sole respiratory quinones detected in and . The major menaquinone components in were tetrahydrogenated with ten isoprene units. Tetrahydrogenated menaquinones with nine isoprene units, however, predominated in . The results of the present study indicate that and should be excluded from the genus can be accommodated in the genus but the taxonomic position of remains equivocal.
