title: Ubiquinones (Coenzyme Q) in hydrogen oxidizing bacteria.
abstract: The isoprenoid quinone content and composition of several strains of the following hydrogen oxidizing bacteria were studied: Xanthobacter autotrophics, Xanthobacter flavus, Paracoccus denitrificans, Pseudomonas pseudoflava, P. carboxydovorans, P. carboxydo-hydrogena. All strains studied contained ubiquinone (UQ) in concentrations between 0.7 and 2.8 μmol/g bacterial dry weight. No menaquinones were found. UQ of all strains (except one) contained side chain lengths of 10isoprenoid units (UQ-10), two strains contained in addition UQ-8. UQ-9 was found in Pseudomonas carboxydohydrogena only.
