[Changes in the activity of glyoxylate cycle enzymes of yeast during hydrocarbon nutrition].

Six strains of Candida guillermondii of different productivity showed a higher isocitrate lyase and malate dehydrogenase activity of cell-free extracts when grown on paraffin than when grown on glucose. In most cases isocitrate dehydrogenase activity was higher on glucose than on paraffin. A positive correlation between isocitrate activity and growth rate was found from studies of the strains of varying growth rate and the cultures cultivated under different conditions (nitrogen content and the presence or absence of biotin or autolysate in the medium).
