ALTERNATIVE RESPIRATORY PATHWAYS IN SCHWANNIOMYCES CASTELLII: INVOLVEMENT IN ENERGY PRODUCTION AND GROWTH

Wild-type and cytochrome-deficient strains of Schwanniomyces castellii were cultivated aerobically on citrate, and the effects of respiratory inhibitors on respiration, ATP levels and energy charge were measured. The obtained results demonstrate that every respiratory pathway of Schwanniomyces castellii involves phosphorylation site I, and suggest that the functioning of this site allows the alternative pathways to produce ATP.
