An object is to provide a method for producing dried microbial cells with a high viable cell survival rate after long-term storage at a high temperature. A method for producing dried microbial cells that achieves the above-mentioned object is characterized in that microbial cells are suspended in a dispersion medium containing a protective agent, an antioxidant, and a chelating agent, followed by drying.

Method for producing dried microbial cells

Provided is a technique for enabling a liquid of microbial cells having an enzymatic activity to be easily stored and used. The technique is a method for killing a microorganism while maintaining the enzyme titer of a microbial cell liquid, characterized by including adjusting the pH of a liquid of microbial cells having an enzymatic activity, and then performing a heating treatment of the liquid, and also the technique is a method for killing a microorganism while maintaining the enzyme titer of a microbial cell liquid, characterized by including adding a carbohydrate to a liquid of microbial cells having an enzymatic activity, and then performing a heating treatment of the liquid.
