Abstract
Menaquinones were the only isoprenoid quinones found in 36 strains representing different species of the genera Nocardia, Mycobacterium, Rhodococcus, Amycolatopsis, Saccharothrix, Streptomyces, Nocardiopsis and Actinomadura. Dihydrogenated menaquinones with nine isoprene units [MK-9(H2)] were the main components isolated from Mycobacterium. Dihydrogenated and tetrahydrogenated menaquinones with eight isoprene units were the predominant compounds identified in typical Rhodococcus and Nocardia strains, respectively. "Nocardia phenotolerans" differed from all of the other Nocardia species included in the study, in that it contained the MK-9(H2) [MK-8(H2)] menaquinone system. Nocardioform bacteria lacking mycolic acids contained tetrahydrogenated menaquinones with nine isoprene units as the main component. The Streptomyces strains studied exhibited complex mixtures of partially saturated menaquinones with nine isoprene units with the hexa- and/or octahydrogenated components predominating. Actinomadurae contained major amounts of hexahydrogenated menaquinones with nine isoprene units. In contrast, the single Nocardiopsis strain examined possessed complex mixtures of menaquinones with ten isoprene units, the dihydrogenated components being main constituents.
