The need to develop a technique for rapid detection of microorganisms continue to exist, despite several attempts made to develop and refine various radiorespirometric methods. In the present work, electrets have been used to develop Electret Radiorespirometric (ERR) technique for rapid detection of microorganisms.' The respired I4C02 released due to utilization of 14C-Glucose by the microorganisms. Resulted in neutralization of surface charge on the electret surface, which was measured as voltage drop on the electret voltage reader. The voltage drop measured was correlated with the presence or absence, and also the inoculum size of the microorganims. The preliminary validation revealed promising results demonstrating potentiality of the technique' to rapidly detect the microorganisms.
