With increasing CO3 2-concentration the molar growth yield of bacteria, from glucose, was increased and, of the fermentation products, formate increased more than the other acids. CO3 2-limited cultures of strain wv1 (Group 2 Butyrivibrio) and strain nor37 (Group 1 Butyrivibrio) incorporated 14CO3 2- into lactate and formate. In nor37, lactate and formate had equal specific activities; in wv1, the formate specific activity was twice that of lactate. Strain wv1 had an active pyruvate synthase and an energy-dependent exchange between CO3 2 -and formate was demonstrated. In strain wv1 butyrate was produced mainly from glucose., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-105-2-287
