Abstract
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.Keywords
