Cell extracts of T. roseopersicina strains BBS and SL, grown in the light in anaerobic conditions and in the dark in aerobic conditions, oxidize sulfite in the presence of cytochrome c and AMP or in the absence of AMP. The oxidation rate, especially AMP-dependent, is higher in the cells cultivated in the dark on a mineral medium. The oxidation of sulfite, in the absence and presence of AMP, is related to the membrane fraction and is inhibited by p-CMB -reductase and sulfite:cytochrome c-oxidoreductase.
