titleOfInvention | A kind of Escherichia coli concentration detection method and system |
abstract | The invention discloses a method and a system for detecting the concentration of Escherichia coli, comprising the following steps: a colorimetric standard group solution configuration step: mixing multiple groups of Escherichia coli suspensions with a first L-Trp solution respectively to form multiple groups of first standard solutions Mixed solution; multiple groups of first standard mixed solutions are placed in a dark environment, and shaken and cultured at a first preset speed and a first preset temperature for a first preset time, and then the first p-dimethylaminobenzene is added respectively. The formaldehyde solution forms multiple sets of second standard mixed solutions, and vibrates according to the second preset time to obtain a colorimetric standard set solution; the pretreatment step of the sample to be tested: the original solution of the sample to be tested is mixed with the second L-Trp solution to form the first solution. an original mixed solution; combined with the second p-dimethylaminobenzaldehyde solution to process the first mixed solution to be tested; colorimetric step: obtaining the predicted concentration value of Escherichia coli by colorimetry. The method for detecting the concentration of Escherichia coli proposed by the present invention achieves a more accurate detection effect through quantitative colorimetric analysis of the enzyme substrate. |
