摘要:
A method for the preparation of a purified enzyme from a fermentation broth by separating the enzyme solution, adding an organic compound selected from carboxylic acids, amino acids, esters of these acids or blends of these compounds and collecting the purified enzyme precipitate.
摘要:
A highly purified alkaline protease preparation is produced by separating a mixture containing amorphous form and crystalline form of alkaline protease from ultrafiltrate containing impurities, through a method which includes the incubation of an aqueous alkaline protease concentrate with sodium chloride and carbohydrate hydrolyse enzymes at an elevated temperature greater than 20 °C and a pH between pH 4.0 and pH 6.5 at constant agitation.
