✦ Synopsis
The influence of different states of oxygen and alkane substrate supply on the metabolism of Candida maltosa during cultivation on n-alkanes has been investigated. At sufficient oxygen and substrate supply a nearly equimolar ratio between the formation of biomass and alkane oxidation was observed. About 45% of the carbon source utilized was incorporated into the biomass. Strong oxygen limitation decreased protein formation and carbon incorporation into the biomass with a simultaneous increase in CO2 formation, whereas periodic changes of oxygen supply only caused a decrease in carbon incorporation into the biomass and an increase in CO2 formation. During cultivation in the presence of an inert hydrocarbon (pristane) it was found that carbon limitation and oxygen saturation diminished the formation of total and nitrogen-containing biomass, whereas carbon and oxygen limitation reduced the formation of total biomass.
