A sensitive, low-temperature spectrophotometric technique was used to detect the presence and relative contents of cytochromes resembling hemoproteins in suspensions of intact cells of 15 strains of anaerobic actinomycetes. The cytochrome content of most cultures was increased by aerated cultivation. Anaerobically grown cells of serotype 2 contained virtually no cytochromes whereas those of serotype 1, and in this order, show an increased concentration of only cytochrome (hemoprotein 559). Under aerobic conditions, was able to synthesize cytochromes and . No correlation was found between spectrophotometric and benzidine test data. Cytochrome spectra may be useful in differentiating serotype 1 from serotype 2 of and differentiating from the other species of studied.
