Fast determination of viable bacterial cells in milk samples using impedimetric sensor and a novel calibration method

For development of an impedimetric biosensor to quantify viable bacterial cells, this work defines the relationships between microbial growth and impedance changes associated with acidification of the culture medium. Performed experiments demonstrated the capacity of the method to detect E.coli concentrations in a range between 10x2 and 10x6 cfu/mL in milk in only 6 hours with 5–12% error margin.
