Abstract: An electrode for the determination of L-Aspartate was prepared.Escherichia coli was used as the biocatalyst and an ammonia gas electrode was used as the base electrode.The effects of the culture medium, immobilized methods of the bacteria and the response characteristics of the electrode were studied.The slope of the L-Aspartate response curve E~-IgCis 55 mV/decade, linear range is 6.0×10-4-8.0×10-3mol/Land life time is 10days.

Key words: L-Aspartate, Miocrobial electrode, Biosensor
