Abstract
265,336. Faithfull, S. E. Dec. 8, 1925. Lactic acid and lactates are produced by fermentation, a gaseous oxidizing material containing free oxygen being introduced to retard the production of butyric acid, and impurities being removed from the lactate solution after fermentation. In an example a hydrolyzed carbohydrate (glucose) is subjected to fermentation with lactic bacteria in slightly acid solution. Slaked lime or calcium carbonate is added to neutralize the acid formed and oxygen or air is injected during the fermentation and as long as calcium lactate is present in the liquor. The solution is then made slightly alkaline and heated nearly to boiling point, which converts any carbohydrates remaining into caramel, which can be filtered off. The solution is concentrated, acidified, and lead lactate or other lead salt or tannin is added to precipitate the nitrogeneous matter present, from which, after filtration, nitrogen may be recovered as ammonia by heating. The solution may be purified by activated carbon and any heavy metals precipitated with sulphuretted hydrogen, leaving a colourless solution of calcium lactate, from which calcium lactate, calcium acid lactate, or lactic acid may be obtained in known manner.
