Process which comprises cultivating a micro-organism which is capable of growing on at least some straight chain hydrocarbons, for example a yeast, such as a Candida tropicalis, cultivation being carried out in the presence of a hydrocarbon feedstock which consists in part of straight chain hydrocarbons in the presence of an aqueous nutrient medium and in the presence of a gas containing free oxygen and thereafter separating from the product, an aqueous phase and a product mixture, the product mixture comprising the micro-organism, unconsumed hydrocarbons and an aqueous phase, thereafter treating the product mixture with an alcohol and a solvent hydrocarbon used in either order or together each part by volume of said product mixture being treated with 0.5 to 2 parts by volume of said alcohol and with 0.5 to 2 parts by volume of said solvent hydrocarbon, the treated product mixture being thereafter subjected to phase separation with recovery of a phase comprising the solvent hydrocarbon and unconsumed hydrocarbons and with recovery of a phase mixture comprising alcohol, water and the micro-organism. |
