Abstract
A biosensor is a biological recognition element that combines a transducer to generate a signal and a signal processing system to identify specific ions or compounds. Biosensors can detect and recognize specific components within the tissues or the cells. A microbial biosensor is an analytical device that uses microorganisms and a physical transducer to detect a quantifiable signal proportional to specific ions or compounds level. Recently, microbial biosensors have been designed for various purposes, including environmental, food, and biomedical applications. Due to their capacity to examine DNA, microbial biosensors are an excellent and suitable alternative to time saving, sophisticated and costly traditional forensic identification methods. The chapter begins with an overview of several sensing technologies widely employed in microbial ...
