Bio-recognition devices have captured special attention because they combine biological specificity and selectivity with electronics to perform environmental and biomedical analysis. Lindane is a recalcitrant pesticide considered potential carcinogen that has caused seriouspollution problems. The purpose of the present study is to evaluate Streptomyces sp. M7 ability to dechlorinate lindane in liquid defined media in adverse culture conditions. Bacterialactivity was monitored by electrochemical impedance spectroscopy. These results confirm that the microorganism adhered to a solid support is able to grow and to metabolize theorganochlorine pesticide as a sole carbon source. Therefore, Streptomyces sp. M7 can be applied for a future development of a prototype for lindane detection and quantification.
