Abstract
1306751 Lactase BAXTER LABORATORIES Inc 26 Jan 1971 3126/71 Heading C3H A method for the production of an acid-active, acid-stable lactase enzyme preparation comprises growing a culture of Aspergillus niger under aerobic fermentation conditions, extracting the growth product with water, slurrying the extract with a hydrated aluminium silicate adsorbent at a pH of from 3 to 6 to adsorb an active lactase component, separating the precipitate and releasing the active lactase component therefrom by adjusting the pH to 7 to 8 with an aqueous alkaline reagent. The silicate may be bentonite or kaolin.
