Resumen:The family Syntrophomonadaceae comprises the genera Syntrophomonas, Pelospora, Syntrophothermus, and Thermosyntropha. All these bacteria are strictly anaerobic and depend on reducing conditions for growth. They are Gram-positive with low DNA content, but in most cases the murein layer is thin and an outer membrane appears, resembling the cell wall architecture of Gram-negative bacteria. Also in Gram-staining, these bacteria mostly behave Gram-negative. Except for Pelospora, all members of this family degrade fatty acids of four carbon atoms or more by beta oxidation, in close association with hydrogen- or formate-utilizing partner organisms, and depend on this association for thermodynamic reasons. Most representatives of this family can be grown in pure culture with crotonate which is dismutated to acetate and butyrate. Pelospora sp. grows by decarboxylation of glutarate or succinate.
