Estimation of pathways of glucose catabolism inRhodotorula gracilis

The metabolic pathways of glucose catabolism inRhodotorula gracilis were studied by means of specifically labelled14C-d-glucose. The presented results indicate that the pentose phosphate cycle is the main pathway of glucose breakdown. The additional pathway, presumably an incomplete sequence of glycolytic reactions operates to a lesser extent. A rough quantitative estimate shows that 60–80% of the assimilated glucose is routed through the pentose phosphate cycle. The lack of metabolic activity under anacrobic conditions is assumed to be caused by a gap in the enzyme sequence of glycolysis between glyceraldehyde-3-phosphate and pyruvate.
