[Excerpt] The detection, monitoring and/or prevention of microorganism growing is of utmost relevance in several research fields, from food to environmental areas, being an important topic either from an academic or an industrial point of view. Conventional methods like plating techniques are the most widely used, being needed novel and faster screening methodologies like electronic noses, electronic tongues (E-tongues) and impedance based methods. In the present work, a potentiometric E-tongue (Fig. 1), comprising 40 lipid polymeric sensor membranes with cross-sensitivity, was used to identify and discriminate three bacteria (Enterococcus faecalis ATCC29212; Staphylococcus aureus ATCC653 and Escherichia coli ATCC29998) at two concentration levels (low and high).
