Abstract: 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.
