Alteromonas and Marinomonas strains contained ubiquinone with eight isoprene units as their most abundant component, whilst ubiquinones with nine isoprene units predominated in Deleya and marine Pseudomonas strains. Members of the genus Shewanella contained both ubiquinones and menaquinones. The presence of two types of isoprenoid quinones in Shewanella is thought to be unique amongst Gram-negative, aerobic bacteria. In addition, methylmenaquinones were also found in Shewanella putrefaciens strains. The results demonstrate that the analysis of isoprenoid quinones offers a rapid and effective method of differentiating between some marine bacteria., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-138-11-2275
