ABSTRACT:
A novel urease and a process for producing the same are disclosed. This novel urease has certain properties that are mainly useful for removing urea from alcoholic liquors or other foods and beverages produced by fermentation. These properties include an optimum pH in an acidic pH range, high stability in a considerably high concentration of alcohol such as in an alcoholic liquor, resistance to high temperatures, and highly specific activity to urea.
This urease can be produced by culturing a certain strain belonging to genus Arthrobacter, disrupting the cultured microbial cells and isolating the product.
