Determination of Kinetic Parameters for Catalytic Isomerization of Glucose to Fructose by immobilized Glucose Isomerase in an Aqueous-Ethanol Medium
Catalytic isomerization of glucose to fructose by immobilized glucose isomerase in an aqueous-ethanol medium was studied. Using Michaelis-Menten equation and Haldane relationship, the main kinetic parameters were determined: Kmf, Vmf, Kmr, Vmr. By comparing the aqueous-ethanol medium with an aqueous solution, the measured values of Kmr and Kmf were increased in the aqueous-ethanol solution, whi...

In the previous paper, one of the authors described "A Survey on the Dextrose Industry in Japan and its Future" in the 1967 issue. As shown in the earlier paper, the supply and demand situation of starch in this country was drastically changed since 1963-64. In the later 1950's, the Japanese Government had a big problem to eliminate the big stock of the over-produced sweet potato starch. Theref...
متن کاملPost-synthetic preparation of Sn-, Ti- and Zr-beta: a facile route to water tolerant, highly active Lewis acidic zeolites.
A two-step procedure for the post-synthetic preparation of Lewis acidic Sn-, Zr- and Ti-zeolite β is reported. Dealumination of a commercially available Al-β zeolite leads to the formation of highly siliceous material containing silanol nests, which can be filled in a second step via the solid-state ion-exchange or impregnation of an appropriate metal precursor. Spectroscopic studies indicate t...
