PURPOSE:To eliminate the overlap of bacteria on each other and to shorten the time for measurement by causing a diluted specimen to be irradiated by excitation light to emit fluorescence and subjecting the fluorescent image of this time to prescribed processing. CONSTITUTION:The specimen 8 in a fermentation tank 1 is supplied by a constant-feed pump 34 at a constant rate to a conduit 24. On the other hand, a diluting liquid is supplied at a constant rate by a constant-feed pump 30 from a diluting liquid tank 35 into the conduit 24. The respective liquids supplied to the conduit 24 are mixed by a stirrer 32 and the mixture is sent to a detecting unit A and is fixed between a cover glass 26 and a plunger 24. The mixture is the irradiated by the excitation light from a light source 2, a light filter 12 and a condenser 10. The fluorescence emitted by the specimen at this time is photographed by a camera 21 after noises are removed therefrom by an optical filter 16. The fluorescent image based on foreign matter exclusive of methane forming bacteria is expelled by an image processor 22 and the concn. or activity of the methanogen is obtd. |
