Device for detecting microorganisms |
摘要 |
An apparatus and method for mixing/agitating microorganism culture bottles includes a wheel in which culture bottles are placed, with the wheel being set at an angle from vertical so that bottles are not inverted during rotation. A sensor such as a florescence or colorimetric sensor for carbon dioxide is disposed along the flat bottom surface of each of the bottles. Once during each revolution the bottles pass across a photodiode/light emitting diode pair (for a calorimetric system). A sensor transmits light emitted by the LED to the photodiode. At the same instant, an infrared reflective objective sensor, emitting on a digital rotary encoder, determines the bottle number. The change in sensor transmittance is directly related to cell growth so that bottles positive for growth can be detected by suitable software.
