CELL COUNT DETERMINATION METHOD AND CELL COUNT DETERMINATION APPARATUS FOR THERMODURIC BACTERIUM

WIPO Patent Application WO/2008/029645

A1

Disclosed is a cell count determination method for a thermoduric bacterium, which can determine the cell count of a thermoduric bacterium within a shorter measurement time. The method comprises the following steps (A) and (B): (A) subjecting a sample to a given thermal treatment to sterilize a predetermined bacterium (a non-thermoduric bacterium such as Escherichia coli) and allow cells of a thermoduric bacterium to remain in the sample; and (B), subsequent to the step (A), adding the sample to a liquid culture medium and measuring the change in concentration of dissolved oxygen in the liquid culture medium using an oxygen electrode to determine the cell count of the thermoduric bacterium.
