Menaquinone composition of some micrococci determined by high performance liquid chromatography

The menaquinone composition of some species of the genus Micrococcus was analysed by high performance liquid chromatography. Both unsaturated and hydrogenated menaquinones were detected. Micrococcus kristinae, M. lylae and M. nishinomiyaensis contained hydrogenated menaquinones while M. sedentarius contained unsaturated menaquinone. The predominant menaquinone isoprenologues of these species are MK-7 (H 2 ), MK-8 (H 2 ), MK-8 (H 2 ) and MK-8, respectively. These observations confirm further the heterogeneity of the genus
