In this work we propose a monitoring methodology through image processing. The images are collected, in situ and from time to time at the same time samples are collected and are measured analytically, in our case the growth of the microorganism. Using the Fourier Transform with the objective of searching for patterns that can be correlated to the analytical measures of concentration of the microorganisms. The results were, from the point of view of the correlations found between the data,
