| Abstract: Glycolate was growth supportive for Moorella thermoacetica ATCC 39073. Growth occurred in undefined and basal culture media containing 20 mM glycolate and was proportional to the concentration of glycolate (10-40 mM). Nitrate inhibited glycolate-dependent growth in the basal medium. Acetate and cell biomass were the major end products recovered from glycolate. The molar ratio (moles of glycolate required to synthesize a mole of acetate) averaged 1.4 and was in close agreement with the theoretical ratio of 1.3 for glycolate-derived acetogenesis. Glycolate-dependent growth yielded approximately 3-fold less biomass per pair of reducing equivalents utilized than did oxalate- or glyoxylate-dependent growth. |
