1. The control of luminescence in a psychrophilic marine Photobacterium is different from that previously reported in other photobacteria. 2. Synthesis of the luminescent system can be inhibited by glucose and by components in tryptone or peptone; this type of inhibition was not reversible by addition of c-AMP. 3. This psychrophilic strain dislays a unique temperature regulation: cells grown below 0°C do not synthesize the luminescent system and appear to be permanently repressed. 4. Dark, 0°C grown cells when shifted to 15°C do not luminesce, but one half of the daughter cells produced from these dark cells synthesized the luminescent system. 5. The mechanism for this type or regulation remains unexplained but may probably by at the transcriptional level. © 1973 Springer-Verlag.
