PROBLEM TO BE SOLVED: To solve a problem that in a chemical application for controlling harmful microorganisms in a mushroom culture, the sterilization in a production chamber is an incomplete state due to enlargement of facilities, influence of medium, etc., an application unevenness wets the chamber with a chemical, raises humidity in the chamber and makes the chamber in an environment to vigorously breed various germs and the cost of the chemical and labor itself for spraying the chemical are terrible. SOLUTION: This method for sterilization in a mushroom culture is characterized by sterilizing a chamber for culturing a mushroom by using an ozone gas. Further the ozone gas is generated by a discharge type ozonizer, and an ozone gas concentration in the chamber is uniformized by using a blower, etc. The sterilization treatment may be automatized by generating an ozone gas in 1 ppm concentration for at least 7 hours only in an inoculation chamber.
