Biosensor containing immobilized Zymomonas mobilis cells for measuring glucose, fructose and sucrose포도당, 과당 및 수크로오스 측정을 위한 고정화 자이모모나스 모빌리스 세포를 포함하는 바이오 센서
A biosensor for the determination of glucose and fructose concentrations is provided. The biosensor is produced by a method which comprises treating Zymomonas mobilis whole cells with an organic solvent such as xylene and n-butanol, immobilizing the treated whole cells onto a support selected from the group consisting of gelatin, collagen, agarose, cellophane and polyacrylamide to give an immobilized whole cell enzyme membrane and adhering the membrane to the surface of a pH electrode to give the biosensor. The resulting biosensor is capable of determning glucose and fructose in high concentrations such as 5 g/L and 50 g/L, respectively. Invertase can be immobilized with the whole cells to provide a biosenser for the determination of sucrose.
