Protein synthesis in the induced formation of catalase in Rhodopseudomonas spheroides.


Rhodopseudomona-s spheroides i a facultative photoheterotroph in which catalase synthesis can be induced by aeration (1). In cultures grown anaerobically in the light, catalase constitutes only about 0.002% of the dry cell mass. In contrast, the catalase content of cultures grown aerobically is as high as 0.3%. If an illuminated, anaerobic culture is… (More)
