“…Although traditional methods such as pH measurements are still used for contamination detection in some industries, new technologies are changing the industrial microbiological quality control scenario. A great variety of new methods, for example, electric impedance measurements, ATP luminescence-based measurement, colorimetry, flow cytometry, epifluorescence, microcalorimetry, nucleic acid technologies, has been developed during the previous decades [1][2][3]. The reason for such diversity is the specific requirements, and the human and equipment resources available in each case.…”
