. J. Bacteriol.
89:
675–679. 1965.—The cytochrome content and respiratory capacity of cells of a strain of
Staphylococcus epidermidis
grown in complex media under aerobic and anaerobic conditions were determined. Difference spectra revealed cytochromes of the
a, b
1
, and
o
types in aerobically grown cells. These cells respired at a rate of 66 μliters of O
2
per hr per mg of cells (dry weight). The cytochrome content of anaerobically grown cells was markedly reduced, and trace amounts only of cytochromes of the
b
1
and
o
type were visible. The respiratory rate, with glucose as substrate, was reduced to about one-tenth of that observed in aerobically grown cells. Cells grown anaerobically in medium supplemented with hemin had as high a content of pigments resembling cytochromes
b
1
and
o
as did aerobically grown cells; the respiratory rate was 60% of that observed in aerobically grown cells. Cytochrome of the
a
type, similar to that found in aerobically grown cells, was not detected.
