摘要： Carboxylic acids are recovered from a fermentation broth by adjusting the pH of a fermentation broth comprised of a carboxylic acid to at least about 6.0 and then heating the pH-adjusted broth to a temperature sufficient to effect the formation of three immiscible phases, one of which is an oily phase rich in the carboxylic acid.

摘要： Biooxidation reactions can be controlled by a method which comprises the steps of: (1) independently adding a substrate and a co-substrate at predetermined rates to a bioxidation reaction mixture comprised of a biocatalyst; (2) measuring the oxygen consumption rate and carbon dioxide evolution rate from the reaction mixture; (3) determining the instantaneous rates of substrate and cosubstrate consumption by solving simultaneous equations relating carbon dioxide evolution rate and oxygen consumption rate to the substrate oxidation stoichiometry, the cosubstrate combustion stoichiometry, and optionally the biomass formation stoichiometry; (4) simultaneously adjusting the substrate and cosubstrate addition rates to the rates of substrate oxidation and cosubstrate consumption in order to maximize the rate of product formation while simultaneously minimizing the rate of cosubstrate usage. The method provides a rapid means of controlling fed-batch biooxidation reactions which can employ in-line techniques and is broadly applicable for diverse oxidation reactions.

摘要： Carboxylic acids and glycerine are made by a continuous splitting process which involves the formation of a presplitting mixture by separately adding the glyceride, an effective lipase in an amount sufficient to produce partial splitting of the glyceride, and water. The water used in the formation of the presplitting mixture is water that has been separated from the glycerin-water effluent stream from the pressure splitter and recycled. The next step involves the pressure splitting which entails mixing the partially split glyceride from the presplitter with water and heating under conditions of temperature and pressure effective to substantially complete the splitting of the glyceride into component fatty acids and a glycerin-water stream. The water is then separated from the glycerine-water stream and the water is recycled to the presplitter.
