Summary Lauryl dimethyl amine oxide was used to isolate reaction centers from a carotenoid‐less mutant, strain G‐9, of Rhodospirillum rubrum. These reaction centers have absorption spectra and light or chemically induced difference spectra very similar to those obtained from Rhodopseudomonas spheroides , strain R‐26. But, unlike those from Rps. spheroides , they are more labile to higher detergent concentrations and to ammonium sulfate. The cytochrome content was estimated to be less than one per 10 P870.
