Embodiment 1
[0055] Example 1: An in-situ fluorescent bacteria microscopic tracing method in a coal rock flow field of the present invention, using fluorescent bacteria as a tracer medium, with the help of fluorescent bacteria that are small (individual size <5 μm) and cannot be further divided, specific wavelengths of light It can be excited to fluoresce under irradiation, has dual-band fluorescence characteristics, the bacteria can be concentrated by centrifugation, and has the characteristics of autonomous avoidance of sensitive factors.
[0056] The specific technical implementation scheme is as follows ( figure 1 ):
[0057] Step (1) bacterial species acquisition, pre-cultivation, and tracer bacteria configuration: select a bacterial species with dual-band fluorescence characteristics, individual size less than 5 μm, and the ability to autonomously evade sensitive factors as tracer bacteria, and pre-cultivate to The flora density reaches 1*10 9 cells / mL, the density of the cultivate...
