“…The taxonomic position of this taxon remains unclear, for while the mycolic acid data indicate an affinity to true corynebacteria, the guanine plus cytosine content (65.5-66.9% G + C; Crombach, 1978) suggests a closer relationship to the rhodococci. Clearly, further comparative studies are required to determine the detailed relationships that exist between caseobacters, corynebacteria and rhodococci.…”

A Survey of the Structures of Mycolic Acids in Corynebacterium and Related Taxa

1982

Acid methanolysates of 104 strains of coryneform and related bacteria were examined for mycolic acids by thin-layer chromatography and mass spectrometry. The mycolic acids of Corynebacterium sensu stricto strains were not uniform in size and structure, and considerable variation existed within the approximate limiting range of C22 to C36. Two species, Corynebacterium bovis and 'Corynebacterium mycetoides', were particularly distinctive; the former had exceptionally low molecular weight mycolic acids (C22 to C32), whereas the latter contained major amounts of mycolates with a side-chain possessing an odd number of carbon atoms. Caseobacter polymorphus contained mycolic acids of a similar size (C30 to C36) to those of true corynebacteria. The mycolates of organisms assigned to the genus Rhodococcus were generally larger (C30 to C56), although a clear distinction between two corynebacteria and rhodococci cannot presently be made by analysis of mycolic acids alone. Strains labelled 'Arthrobacter roseoparaffinus', Corynebacterium equi and Corynebacterium hoagii contained mycolic esters with molecular weights 'intermediate' in size between those of true corynebacteria and rhodococci. The mycolic acid data correlate well with other major trends in coryneform taxonomy and support earlier suggestions that they are of value in the classification of the group.

We hybridized 23s 2-14C-labeled ribosomal ribonucleic acids (rRNAs) from type strains Pseudomonas fluorescens ATCC 13525, Pseudomonas acidovorans ATCC 15668, Pseudomonas solanacearum NCPPB 325, and Xanthomonas campestris NCPPB 528 with deoxyribonucleic acids (DNAs) from 65 Pseudomonus strains, 23 Xanthomonas strains, and 148 mostly gram-negative strains belonging to 43 genera and 93 species and subspecies including more than 60 type strains. Our findings confirm and extend the findings derived from ribonucleic acid hybridizations by the Berkeley group, but differed in some respects from the groupings of Pseudomonas in Bergey 's Manual of Determinative Bacteriology, 8th ed. The genus Pseudomonas Migula 1894, 237 was divided into three large, distinct groups. The PseudomonasJIuorescens rRNA branch contains Pseudomonus aeruginosa, Pseudomonas fluorescens, Pseudomonas chlororaphis, Pseudomonas aureofaciens, Pseudomonas syringae, Pseudomonas putida, Pseudomonas stutzeri, Pseudomonas mendocina, Pseudomonas cichorii, Pseudomonas alcaligenes, and Pseudomonas pseudoalcaligenes. The Pseudomonas acidovorans rRNA branch contains Pseudomonas acidovorans, Pseudomonas testosteroni, Pseudomonas delajieldii, Pseudomonas facilis, Pseudomonas palleronii, Pseudomonas saccharophila, and Pseudomonas flava. The third rRNA branch contains Pseudomonas solanacearum, Pseudomonas cepacia, Pseudomonas marginata, Pseudomonas caryophylli, and Pseudomonas lemoignei. Each of these rRNA branches is as heterogeneous as a genus. The Pseudomonas solanacearum and Pseudomonas acidovorans rRNA branches are about as far removed from each other as they are from the genera Janthinobacterium and Derxia and the authentic genus Alcaligenes. These branches are members of the third rRNA superfamily. The Pseudomonas fluorescens rRNA branch is quite different, as it is a member of the second rRNA superfamily, which also contains Azotobacter, Azomonas, Xanthomonas, and some other genera. Along with data from rRNA hybridizations involving. many different gram-negative taxa, these results show clearly that the three Pseudomonas rRNA branches differ at least at the genus level. The genus Xanthomonas is separate in its own right. It constitutes a very tight cluster consisting of Xanthomonas campestris, Xanthomonas fragariae, Xanthomonas axonopodis, and Xanthomonas albilineans (Xanthomonas campestris covers older species names no longer in use). Xanthomonas (Aplanobacter) populi has rRNA cistrons that are indistinguishable from the rRNA cistrons of the xanthomonads mentioned above. There are a number of misnamed taxa. Pseudomonas maltophilia is a somewhat unusual member of Xanthomonas; likewise, Pseudomonas diminuta and Pseudomonas vesicularis are not members of the genus Pseudomonas, and Xanthomonas ampelina is definitely not a member of the genus Xanthomonas. The exact taxonomic positions of the latter three species are unknown. A quantitative comparison showed that fine differentiation of strains by means of DNA-DNA hybridization under stringent conditions at TOR ...

“…Menaquinones, 2-methyl-3-polyprenyl-1,4-naphthoquinones, display structural variations which may include the length and degree of hydrogenation of the polyprenyl side-chain, hydroxylation (Allen et al, 1967) and possibly epoxidation (Friis et al, 1967). Ubiquinones, 2,3-dimethoxy-5-methyl-6-polyprenyl-1,4-benzoquinones, also show variations in the length and degree of saturation of the side-chain (Thomson, 1971).…”

Menaquinones were the only isoprenoid quinones found in 85 of the 95 coryneform bacteria examined. Dihydromenaquinones having nine isoprene units were the main components isolated from Corynebacterium bovis, from other glutamic acid-producing strains, and from Arthrobacter globiformis and related species. Dihydromenaquinones with eight isoprene units were found in Brevibacterium linens, the remaining Corynebacterium species and strains probably belonging to the genus Rhodococcus. Tetrahydromenaquinones with eight isoprene units were found in Arthrobacter simplex and Arthrobacter tumescens, and with nine isoprene units in Cellulomonas and Oerskovia. Kurthiu and Curtobacterium were characterized by menaquinones with seven and nine isoprene units, respectively, and Microbacterium lacticum and Corynebacterium aquaticum had comparable amounts of menaquinones with 10 and 11 isoprene units. Strains received as Brevibacterium leucinophagum, Corynebacterium autotrophicurn, Corynebacterium nephridii, Mycobacterium jlavurn, Mycoplana rubru and Protaminobucter ruber contained ubiquinones as their sole isoprenoid quinones. The isoprenoid quinone data correlate well with major trends in coryneform taxonomy and are of value in the classification of coryneform and related bacteria.
