Resumen
An apparatus and a procedure to detect and quantify the microorganisms concentration in anaerobe ecosystems, for instance, sulfate-reducing bacteria in oil producing systems or industrial or urban waste-waters production systems, as well as in aerobe microbial ecosystems, for instance in the industrial, clinical fields, etc. The apparatus analyzes the growth of microorganisms in cells provided with a culture medium by conducting automatic, continuous, and simultaneous measurements of the impedance components between at least two electrodes immersed in the culture medium and the turbidity measurements of the inoculated medium. The use of two incubators makes it possible to conduct simultaneous analysis at two different temperatures. The determination of the growth Threshold Detection Time (TDT) makes it possible to quantify the microorganisms concentration in an unknown sample.
