FIG. 5.
Spectral characterization of membrane fractions isolated from M. smegmatis grown in an oxystat. The spectral profiles of purified membrane fractions from M. smegmatis grown at 21% (A) and 1% (B) air saturation are shown. Reduction was accomplished by the addition of sodium dithionite, and oxidation was accomplished by the addition of potassium ferricyanide.
