PURPOSE:To enable real-time determination of the number of microorganisms in air, by using a microorganism counter composed of a sample air pretreatment region to facilitate the counting of microorganisms by dyeing the microorganism with a fluorescent dye, a region to excite the microorganisms dyed with a fluorescent dye with fluorescent light and a region to detect the microorganisms. CONSTITUTION:A microorganism detecting region 8 is provided with a light source 9 to excite microorganisms with fluorescent light and a detector 10 to detect the fluorescent light emitted by the excitation with light of the light source 9. Sample air is supplied to the microorganism detection region 8 with an air pump 13. Microorganisms in the sample air sucked to the microorganism detecting region 8 with the air pump 13 are dyed with a fluorescent dye in a pretreatment region region 1. Since the counter can be easily automated and unmanned, the number of microorganisms in air can be determined in real time without culturing the microorganisms. |
