The specific rate of growth and the generation time of four different strains of Candida were investigated. C. lipolytica IFP 29 has the highest growth rate and biomass. Three distinct phases of growth were observed. The data obtained in this report showed that the enzymatic systems of C. lipolytica IFP oxidizing glucose are constitutive but those oxidizing alkanes are adaptive. The carbon nitrogen balance on B.P. (British Petroleum) cut was obtained. The low‐rate of C CO2 /C Cell was attributed to the excretion of keto acids and organic acids into the fermentation liquor. α‐Ketoglutaric and pyruvic acids with organic acids were detected in the fermentation broth. The amounts of keto acids and organic acids were coincided with the growth phases.
