发明名称 Vacuum detection of bacteria
摘要 A sample of material to be tested for the presence of oxygen consuming bacteria is introduced into a sealable container partially filled with a culture medium; the remainder of the container being filled with an oxygen containing gas, the container being connected to means for sensing the production of a vacuum therein. The container and its contents are subjected to conditions conducive to bacterial growth for a predetermined period sufficient for growth of bacteria to consume some of the oxygen, during which time the pressure of the gas in the container is monitored and compared to the initial pressure in order to detect the production of a vacuum due to consumption of oxygen by bacteria from the test sample, thereby indicating the presence or absence of oxygen consuming bacteria in the sample of test material.
