Eubacterium acidaminophilum combines the oxidation of amino acids such as alanine or valine with the reduction of glycine to acetate in a two-substrate fermentation (Stickland reaction). In the absence of glycine, dense cell suspensions oxidized alanine or valine only to a small extent, with limited production of hydrogen and acetate. Experiments with 14(More)
