Microbial based sensor for the measurement of glucose in serum and urine

A microbial based biosensor for the measurement of glucose in serum and wine has been developed. Bscillus licheniformis, a microbial, was used in the cytosensor as the producer of glucose oxidase that are required in the biosensor. The influence of the types of microbes, enzyme immobilizing techniques and the carrier for the enzyme or microbial were studied. The new sensor has the advantages of high stability, low cost and easier preservation. It is the first time to develop a cytosensor with a mimic enzyme catalyzed fluorescence reaction for the measurement of glucose in serum and urine.
