By using the continuous culture technique, the transition from aerobiosis to anaerobiosis and its effect on a number of enzymes has been investigated in Escherichia coli K-12. A decrease in the oxygen partial pressure below 28.0 mm of Hg resulted firstly in an increase of the respiratory enzymes (reduced nicotinamide adenine dinucleotide [NADHI oxidase, 2.53-fold; succinic dehydrogenase, 1.4-fold; cytochrome b1, 3.91-fold; and cytochrome a2, 2.45-fold) before the electron transport system
