Abstract
The aerobic Gram-negative gliding bacteria, Flexibacter elegans (Cytophagales) and Myxococcus fulvus (Myxobacterales) contain exclusively menaquinones as isoprenoid quinones. Each strain produces 3 different menaquinones. The menaqinone content of Flexibacter elegans was 1.5 μmol/g dry cells, with MK-7 as the main compound (>99%). MK-7 was identified by mass and n.m.r. spectroscopy. Myxococcus fulvus contained 2.1 μmol menaquinones per g dry mass, with more than 90% being MK-8.
