A procedure is described for the selective enrichment of anoxygenic photosynthetic bacteria from diverse natural sources containing numerous types of microorganisms. The enrichment medium contains a mixture of organic acid carbon sources, and the conditions used favor the growth of organisms that can multiply relatively rapidly anaerobically with N 2 as the nitrogen source and light as the source of growth energy; the development of oxygenic cyanobacteria is effectively excluded.
