摘要：

A mediated enzyme electrode was developed for the determination of L-glutamate, based on the immobilization of L-glutamate oxidase from Streptomyces sp. X 119-6. A graphite working electrode was used with 1,1 dimethylferrocene (DMF) as electron mediator. The electrode responded linearly to L-glutamate over the range 0.2 to 2 mM (0.029-0.29 g/1). The enzyme electrode was applied to the measurement of L-glutamate in various foodstuffs.
