Method for quickly detecting microorganisms

The invention relates to a method for quickly detecting microorganisms, which includes the following steps: a, modeling: standard microorganisms are added in a culture solution to grow in the culture solution, signals generated during the growth of the standard microorganisms are detected, and the detection time of the standard microorganisms are recorded when the detection signals are reduced at the end of the lag growth phase of the standard microorganisms; and the standard model of the concentration and the detection time of the microorganisms is obtained as per the concentration and the detection time of the standard microorganisms; and b, detection: a to-be-detected microorganism is added in the culture solution to grow in the culture solution, signals generated during the growth of the to-be-detected microorganism is detected, and the detection time of the to-be-detected microorganism is recorded when the detection signals are reduced at the end of the lag growth phase of the to-be-detected microorganism; and the concentration of the to-be-detected microorganism is obtained as per the detection time and the standard model of the to-be-detected microorganism. The invention has the advantages that the method is quick and accurate and has wide application range and the like, and can effectively eliminate the background interference.
