Abstract
The present invention provides a culture medium for microbiological tests prepared by treating medium components containing adenosine triphosphate (ATP) with an acidic phosphatase as well as a microbiological test method characterized by using said culture medium for microbiological tests as the 1st aspect of the present invention when the microbiological test is conducted by ATP-luciferase method. When using the culture medium for microbiological tests according to the present invention, in a microbiological test by ATP-luciferase method, the emission derived from the culture medium is suppressed stably at a very low level, and there is no possibility that the emission derived from a substance other than a microorganism affects the measurement. In addition, the microbiological test method according to the present invention is simple, accurate and highly reliable since it employs the culture medium for microbiological tests according to the present invention.
