Abstract

SUMMARY: Strains of and contained cytochrome Peaks corresponding to cytochromes and a carbon monoxide-binding pigment were also observed. By means of dualwavelength experiments with crude membrane fractions it was established that cytochrome functioned in anaerobic electron transport to fumarate. In and one strain of which reduced nitrate, anaerobic electron transport to nitrate was found. Glycerol i-phosphate and NADH were active as hydrogen donors for cytochrome reduction in glycerol-grown lactate and pyruvate were active in lactate-grown and NADH was active in lactose-grown Oxidative phosphorylation associated with these electron transfer systems might explain the high molar growth yields previously found for these micro-organisms. Fermentation products were measured in supernatant fluids of cultures grown in the presence and absence of nitrate. Nitrate did not influence the fermentation of lactose to lactate by and inhibited propionate formation by
