[Detection of cyanide resistant respiration among Candida lipolytics yeasts].

Conditions causing cyanide-resistant respiration were studied in the yeast Candida lipolytica. This type of respiration was found when the culture growing on glucose, glycerol, hexadecane, or acetate exhuasted the substrate and passed from the logarithmic to stationary growth phase; the same phenomenon can be induced by exhaustion of phosphorus or nitrogen in the glucose medium. The yeast culture growing on lactate, ethanol, pyruvate, alpha-ketoglutarate, malate, or succinate is characterized by cyanide-resistant respiration even at the beginning of the logarithmic growth phase. The values of pH in the incubation medium have no effect on the time of manifestation of cyanide-resistant respiration.
