    摘要: A process for the recovery of an intracellular enzyme from an aerobic soil microorganism is disclosed. The recovery method is carried out by(a) forming an aqueous suspension of microbial cells containing the desired intracellular enzyme,(b) disrupting the microbial cells in the suspension to release the enzyme from the cells, and(c) before, during, or after step (b) and prior to removal of disrupted microbial cells and other cellular components, introducing a water-miscible organic solvent into the suspension to form a mixture of the organic solvent and the enzyme-containing suspension.The desired enzyme is retained in the liquid phase of the mixture formed in step (c) while undesired cellular components such as other microbial cell proteins precipitate therefrom.
