Abstract

Selected members of the family Pohl 1981 were investigated for their lipoquinone contents by using high-performance liquid chromatography. In addition to ubiquinones and demethylmenaquinones, menaquinones (MK-7 or MK-8 or both) were detected, mostly as minor naphthoquinone components, in several , and related species. Previous studies that relied on difference spectrophotometry and thin-layer chromatography did not identify menaquinone components in lipid extracts of members of the The view that this family can be differentiated from the and other fermenting gram-negative bacteria by a lack of menaquinones cannot be maintained. Although the situation seems to be more complex than previously recognized, the distribution patterns of lipoquinone structural types and their isoprenologs appear to remain a valuable chemotaxonomic tool for these bacteria.
