Definitions
- the present invention relates to a luminescence measuring apparatus that detects the presence of cells contained in a sample or measures the number of cells by luminescence measurement.
- CFU Colony Forming Unit
- ATP Addenosine Triphosphate, adenosine triphosphate luminescence method is known as a quicker measurement method than the culture method.
- ATP luminescence method luminescence obtained by reacting ATP extracted from living microorganisms in a sample with a luminescent reagent is measured by a photodetection unit such as a photomultiplier tube, and viable cells are calculated from the obtained luminescence amount.
- the number is estimated (see Non-Patent Document 1), and measurement is performed by installing a sample container in the vicinity of the light detection unit. For this reason, light emission derived from a single container, which was not detected by the structure and sensitivity of a general luminescence measuring device, may be detected.
- the amount of ATP corresponding to one bacterium is very small compared to the amount of ATP contained in large cells such as fungi and humans. For this reason, when a substance derived from an operator or an external environment enters the luminescence measuring apparatus to cause microbial contamination or ATP contamination, the amount of bacterial ATP is excessively estimated.
- Patent Document 2 describes an automatic chemical analyzer in which a reagent storage is installed inside a reaction disk in which a plurality of reaction tubes are installed.

- ATP to be detected by the ATP luminescence method is an organic compound that is an energy source for life activity and exists in cells of all living organisms.
- ATP luminescence method generally, ATP derived from a dead microorganism in a sample is decomposed with an enzyme, ATP in a living microorganism is extracted with a surfactant or the like, and the extracted ATP is converted into, for example, luciferase / luciferin.
- the luminescence reagent is reacted with a luminescent reagent such as The luminescence thus obtained is measured with a photodetector such as a photomultiplier tube, and the number of viable cells contained in the sample is estimated from the amount of luminescence (see Non-Patent Document 1).
- the detection sensitivity of the current general ATP method is 1 ⁇ 10 ⁇ 15 to 1 ⁇ 10 ⁇ 16 mol ATP (1 to 0.1 fmol), and has not reached the detection sensitivity of ATP corresponding to one bacterium, It corresponds to about 100 to 1000 bacteria.
- the ATP method cannot confirm the number or presence of 1 to 100 microorganisms.
- the present inventors have developed a high-sensitivity luminescence measuring apparatus capable of detecting 1 ⁇ 10 ⁇ 18 mol ATP corresponding to one bacterium, exceeding the limit of detection sensitivity by the current ATP luminescence method. In the process, we confirmed the luminescence phenomenon that was treated as an error so far and was not reflected in the luminescence measurement result.
- the presence or absence of background noise from the sample container is determined by the number of times the door of the luminescence measuring device is opened and closed in the measurement environment, the opening and closing time, and the sample to the sample container.
