Seeliger, Sabine Kolb, Sylvie application/pdf 1998 Malonomonas rubra is a microaerotolerant fermenting bacterium which can maintain its energy metabolism for growth by decarboxylation of malonate to acetate. 16S rRNA sequence analysis revealed that M. rubra is closely related to the cluster of mesophilic sulfur-reducing bacteria within the delta subclass of the Proteobacteria, with the fermenting bacterium Pelobacter acidigallici and the sulfur reducers Desulfuromusa kysingii, D. bakii and D. succinoxidans as closest relatives. The cells contain high amounts (up to 12% of the total cell protein content) of a c-type cytochrome which is present mainly (> 60%) in the cytoplasm and to minor parts in the periplasm (> 20%) and associated with the membrane fraction (> 10%), independent of the growth substrate. This cytochrome is a tetraheme cytochrome of 13,700 Da molecular mass with a midpoint redox potential of -0.210 V.M. rubra does not reduce sulfur or ferric iron compounds. Since this cytochrome appears not to be involved in the energy metabolism it is concluded that it is a remnant of sulfur-reducing ancestors of this bacterium, without a conceivable physiological function in its present energy metabolism.
