Method of early observation of colonies of microorganisms

摘要

A method of observing a sample, the sample comprising microorganisms bathed in a non-transparent culture medium, the culture medium being conducive to the development of microorganisms, the sample being placed between a light source and a sensor of light. image, the method comprising: illumination of the sample by the light source, the light source emitting light propagating along a propagation axis; acquisition of an image of the sample by the image sensor; from the acquired image, characterization of microorganisms; the process being characterized in that: the culture medium extends, parallel to the axis of propagation, with a thickness less than 500 μm.
