(57) [Summary] [Structure] Dehydrogenase enzyme, which changes from colorless to colored state, is used as a substrate to detect the presence of microbial dehydrogenase enzyme. In a device for the detection of free reducing compounds, and the filter material in the device is in direct contact with the absorbent material, As a result, a microorganism detection instrument that can easily pass through a filter. [Effects] Free reducing compounds present in the sample pass through the filter, only bacteria are collected on the filter membrane, the substrate is reduced by the bacterial dehydrogenase and colored, and the microorganisms in the sample are detected. . |
