Abstract
By performing a comprehensive analysis of nanaerobic respiration in Bacteroides fragilis , we show that this organism maintains capabilities for anaerobic respiration on fumarate and nanaerobic respiration on oxygen simultaneously. The contribution of the two NADH:quinone oxidoreductases and the composition of the quinone pool are the same under both conditions.
