    摘要: A novel superoxide dismutase prepared from a superoxide dismutase-producing strain of the genus Nocardiopsis. The enzyme is a tetramer with a molecular weight of about 8.8.times.10.sup.4, composed of sub-units of about 2.2.times.10.sup.4. The superoxide dismutase contains 1.56 g-atoms of iron per mole but no copper or manganese. Potassium cyanide at a concentration of 1 mM does not inhibit activity, however exponential inactivation is caused by 5 mM hydrogen peroxide.

    摘要: This invention relates to a process for preparation of a novel lipase. The process is characterized by culturing a microorganism belonging to Staphylococcus capitis and capable of producing lipase in a culture medium to accumulate lipase in the cultured broth and recovering the lipase from the broth. Since the pH of this lipase is in a slightly alkali region and the lipase substantially completely converts glyceride to fatty acids and glycerin, it is useful for the economic preparation of fatty acids by the hydrolysis of fats or oils.
