| Abstrakt: | The uptake of hydrocarbons by yeasts is measured by gravimetric determination of intracellular accumulated N‐free compounds as well as by detection of tritium‐labeled hydrocarbons. The aim of the investigations is to compare the uptake of n‐alcanes and aromatics with respect to the conditions of yeast fermentation on gas oil. Aromatics in comparison to n‐alcanes are taken up in very little amounts. The uptake of n‐alcanes is dependent on the chain length. According to increasing chain length in the range of C10– C16the velocity of uptake is increased whereas the optimal pH‐value is decreased. In the presence of dimethylsulfoxide the uptake of n‐alcanes is markedly increased whereas the uptake of aromatics is decreased. A mechanism of hydrocarbon uptake is discussed characterized by obligate participation of metabolic active cells and hydrocarbon selectivity. |
