PROBLEM TO BE SOLVED: To address the problem that although livestock products and aquatic products have relatively low fluorescent noise, agricultural products, especially green and yellow vegetables have a significant problem with fluorescent noise due to the inclusion of pigments, a novel automatic detection method of fluorescent signals has been developed which does not generate noise in an even wider range of foods.;SOLUTION: A novel microbial test method which automatically detects fluorescent signals and does not generate noise by detection, by means of detecting a specific color and brightness of a DNA probe-derived fluorescent signal on a membrane filter using a low magnification optical system on proliferating bacteria, using a culture combined in situ hybridization method.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
