Abstract:Cells of Zymomonas mobilis possessing glucose-fructose oxidoreductase and gluconolactonase were permeabilized with toluene and co-immobilized with invertase within a gelatin membrane. This membrane was coated over a pH electrode, and the resulting biosensor was placed in a flow-through cell to develop a flow injection analysis (FIA) system for the specific determination of glucose, fructose, and sucrose. Peak height resulting from the production of hydrogen ion was correlated with sugar concentration, and the … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
