| Abstract: | Low-temperature cytochrome spectra of 18 different species of bacteria were examined using fourth-order finite difference analysis. In all of the organisms studied, new cytochrome alpha absorption bands were resolved. On the basis of wavelengths, these bands may be tentatively assigned to two possible c-type cytochromes and two or more b-type cytochromes. Multiple or split bands associated with a single cytochrome species could, however, account for certain sets of the bands detected. |
