Isoprenoid Quinone Composition as a Guide to the Classification of Listeria, Brochothrix, Erysipelothrix and Caryophanon

Abstract
Representatives of the genera Brochothrix, Caryophanon and Listeria all contained fully unsaturated menaquinones as their sole isoprenoid quinones but E. rhusiopathiae contained neither menaquinones nor ubiquinones. Menaquinones with 6 isoprene units were the major isoprenologues in C. tenue whereas menaquinones with 7 isoprene units predominated in B. thermosphacta, L. grayi, L. monocytogenes and L. murrayi. L. denitrificans had menaquinones with 9 isoprene units.
