INTEGRATED BIOTECHNOLOGICAL PRODUCTION PR OCESSES

Manufacturing processes for ethanol and butanol are investigated with respect to reduction of product inhibition by integration with reverse d osmosis, pervaporation, extraction, adsorption, flash evaporation, v acuum evaporation, and gas stripping. The integration of lactic acid f ormation with precipitation, extraction, electrodialysis, ion excange, and crystallization are considered. Adsorption, extraction and crysta llization are examined as possible integrated recovery processes for a ntibiotics production. The possible future integrated use of adsorptio n, chromatography, membrane chromatography, extraction and flotation f or protein production processes is discussed.
