Title:
METHOD FOR REMOVING BIOLOGICAL HIGH-MOLECULAR MATERIAL
Document Type and Number:
Japanese Patent JP2006115730
Kind Code:
A
Abstract:

To provide a method for removing biological high-molecular materials from an alkaline liquid, which has been difficult to handle so far, and to provide a method for isolating/refining a useful material produced by utilizing such biological high-molecular materials.

The method for removing biological high-molecular materials comprises the step of mixing a cationic high-molecular compound into the biological high-molecular materials contained in an alkaline liquid and separating the resultant coagulated matter. By this method, such biological high-molecular materials as microorganisms and/or enzymes can be removed from an alkaline liquid. In a method for producing a useful material using a biological high-molecular material, the above method is applicable as the step of removing the biological high-molecular material. This production method is useful as a method for producing e.g. an optically active β-hydroxyamino acid.
