Abstract
The role of methanol, ethanol and sorbitol oleate on the growth of Candida lipolyrica on n-alkane substrate was studied by changing the concentrations of these solubilizing or emulsifying agents. These three substances enhanced the yeast growth at low concentration ranges, but beyond a critical concentration, exhibited inhibitory effects.
At an optimal concentration of solubilizing agent, the maximum growth rate was multiplied by 1,95 (CH30H), 1,9 (CH3CH20H) and 1,5 (sorbitol oleate). The stimulating effects may be due to increased solubility of n-alkane substrate. The modulization of the growth enhancement (E) with the concentration of the solubilizing agent (P) is performed.
