glucose, as the major energy source in cellular metabolism, plays an important role in the natural growth of cells. herein, a simple, rapid and low-cost method for the glucose determination by utilizing glucose oxidase and cdte/thioglycolic acid (tga) quantum dots (qds) on a thin layer chromatography (tlc) plate has been described. the detection was based on the combination of the glucose enzym...

direct electron transferring of glucose oxidase was investigated   on reduced graphene and graphene oxide templates. the direct electrochemistry   glucose oxidase on   graphene showed a cyclic voltammograms corresponding to the fad/fadh 2   redox couple with an anodic, cathodic and formal potential of -430, -460 and   -445 mv, respectively in 0.1 m phosphate buffer solution and air saturated   ...

the surface parameter of nanoparticles such as hydrophobicity and a hydrophilicity on protein structure and function is very important. in this study, conformational changes of glucose oxidase (gox) in the mercaptopurine: gnps and 11-mercaptoundecanoic acid: gnps as a hydrophobic and a hydrophilic gnps surface was investigated by various spectroscopic techniques, including: uv-vis absorption, f...

The present study is concerned with the production of glucose oxidase (GOD) from thermophilic Penicillium sp. in a 250 mL shake flask. Fourteen different strains of thermophilic Penicillium sp. were isolated from the soil and were screened for glucose oxidase production. IIBP-13 strain gave maximum extra-cellular glucose oxidase production as compared to other isolates. The effect of submerged ...

IAULLFR (1) first demonstrated that fl-glucose oxidase promoted the oxidation of glucose by molecular oxygen to gluconic acid. Franke and Lorenz (2) discovered that hydrogen peroxide is simultaneously produced in this reaction. Keston (3), Comes (4), and Free et at. (5) made the first practical application of the use of glucose oxidase in the estimation of glucose in urine by impregnating paper...

Glucose oxidase is an important enzyme hydrolyzing for its hydrolyzing activity on glucos. It possesses and has a wide board of applications in different industries such as bakery, pharmaceutical, plant pathology and biosensors. In this study, yeast (Saccharomyces cerevisiae) was transformed successfully by the glucose oxidase gene (gox) obtained from Penicillium funicolusum. The secreted gluco...
