Novel, thick-film biosensors have been developed for the determination of l-glutamate in foodstuffs. The sensors were prepared by immobilization of l-glutamate oxidase by using polycarbamylsulfonate-hydrogel on a thick-film sensor. l-Glutamate oxidases obtained from Streptomyces sp. with different d...
