Development of impedancemetric and biochemical methods for detecting low bacterial contaminations in complex liquid media

Abstract : Consumers are more and more concerned by the risk put on their health by consumer goods. In this context, industries have to certify the harmlessness of their product. Especially, the microbiological risk is a particular threat in many sectors, including the food industries. It is therefore strategic to master techniques that can assess this risk in an accurate and fast manner. Developing such techniques was the aim of the Microqual European project, which the researches presented here contributed to. They more specifically addressed the detection issue, through the development of a new prototype device for the impedancemetric measurement of the bacterial growth. They also dealt with an original concentration method, based on the use of immobilized lectins on the surface of paramagnetic microbeads, and lead to the setup of the necessary technical toolkit for the future development of this method.
