In Vitro Discrimination of Bacterial Volatile Compound Patterns Using a Gas Sensor Array

This paper illustrates that an electronic nose applied to the measure of the headspace cultures of Salmonella serotypes can discriminate among different strains. Salmonella is one of the main bacteria causing food borne illnesses, this there is a great interest for fast identification methods. Standard detection methods for Salmonella food contamination have limited performance in terms of costs and rapidity. Electronic noses are among the technologies that supposedly can improve the management of Salmonella infections. Preliminary experiments are discussed in this paper; results confirm that electronic noses offer a viable technology for rapid identification of bacteria.
