Effects of 4-[beta-(diethylamino)-ethoxy]-benzophenone upon carotenogenesis in Rhodospirillum rubrum.
Carotenoid production was determined in illuminated anaerobically maintained cultures of Rhodospirillum rubrum in media with and without 4-[beta-(diethylamino)-ethoxy]-benzophenone. In treated cultures, lycopene--which normally is not produced by R. rubrum--accumulated as the predominant pigment, and total carotenoids increased five- to sixfold.
