Title:
METHOD FOR PRODUCING DRY MICROBIAL CELL POWDER
Document Type and Number:
WIPO Patent Application WO/2012/141244
Kind Code:
A1
Abstract:
The purpose of the invention is to develop a means capable of maintaining the enzymatic activity of a microorganism even in a dry state. Provided is a method for producing a dry microbial cell powder maintaining an enzyme titer, characterized by comprising adding a carbohydrate to a liquid of microbial cells having an enzymatic activity and drying the liquid. Also provided is a dry microbial cell powder obtained by the method.
