ABSTRACT:
Fast microbial detection is accomplished without an indicator interfering with microorganism growth, without a culture medium degrading the performance of an indicator and without a color of test sample adversely effecting th microbial detection process. A container has a portion which accommodates a fluid culture medium, and has a portion which accommodates a CO2indicator. A CO2gas-permeable membrane isolates the CO2indicator from the fluid culture medium. The test sample is added in the fluid culture medium and then the container is sealed. The determination of the presence of microorganisms is accomplished by verifying a color change of a CO2indicator. The quantity of mircoorganisms is determined by measuring time from when the container is sealed until an indicator portion has a color change.
