NOVELTY - Method for producing cells, involves dissolving fat-soluble substances of the cells, mixing cell culture solution and fat-soluble substance extracting solvent to obtain mixed solution, separating the cells from the mixed solution into solvent layer and fat-soluble substance layer, and fractionating cell separated solution into water and fat-soluble substance-solvent in which the fat-soluble substances of the cell culture solution are dissolved in the fat-soluble substance extracting solvent.    USE - The method and apparatus are useful for producing cells and fat-soluble substances chosen from cellulose, hemicellulose, monosaccharide and oligosaccharide and biogas preferably hydrogen (generated during culturing process) (all claimed).    ADVANTAGE - The method and apparatus enables production of cells without injury and fat-soluble substances from the cell culture solution in an inexpensive and highly efficient manner.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for apparatus (1) which has culturing device (10) for culturing cells containing fat-soluble substances, solvent device (20) for storing and supplying the fat-soluble substance extracting solvent for dissolving the fat-soluble substances of the cells, mixing device (30) for mixing the cell culture solution from the culturing device and the fat-soluble substance extracting solvent from the solvent device, separation device (40) for separating the cells from the mixture solution mixed by the mixing device, fractionating device (50) for fractionating the cell separated solution from the separating device into water and the fat-soluble substance-solvent, cell storing device (60) for storing or treating the cells separated by the separating device, and fat-soluble substances-solvent storing device (70) for storing or treating the fat-soluble substance-solvent fractionated by the fractionating device.
