The respiratory quinone composition of Wolinella succinogenes was investigated. Unsaturated menaquinones with six isoprene units (2‐methyl‐3‐hexaprenyl‐1,4‐naphthoquinone) was found to be the major isoprenoid quinone. Substantial levels of a methyl‐substituted menaquinone was also present. Mass spectrometry and proton nuclear magnetic resonance spectrometry indicated the methyl‐substituted quinone corresponded to 2‐, [5 or 8]‐ dimethyl‐3‐hexaprenyl‐1,4‐naphthoquinone.
