Title:
PRODUCTION OF CATALASE
Document Type and Number:
Japanese Patent JPH01168281
Kind Code:
A
Abstract:
PURPOSE: To industrially produce a catalase using extremely inexpensive culture medium without carrying out aseptic control, by using a microorganism group obtained by cultivating a microorganism group in an activated sludge in a hydrogen peroxide-containing liquid and having acquired hydrogen peroxide resistance.
CONSTITUTION: A microorganism in an activated sludge is cultivated in a liquid containing hydrogen peroxide to provide a microorganism having resistance acquired to hydrogen peroxide. Then the microorganism group is cultivated preferably at 20W30°C and pH6W8 under aerobic conditions to produce the aimed catalase and then the aimed catalase is collected from the above- mentioned cultivation product.
