Witryna25 sty 2024 · In the immobilized urease system, the observed shift of the activity-pH curve to lower pH is hypothesized to be the direct consequence of ionic binding. The … Witryna5 mar 2024 · The present work describes the inhibition studies of free as well as immobilized urease by different heavy metals. Porous silicon (PS) films prepared by electrochemical etching were used for urease immobilization by physical adsorption. The enzyme was subjected to varying concentrations of Cr6+, Cr3+, Cu2+, Fe2+, Cd2+ …

Results of … WitrynaThe activity of immobilized urease on it was 0.169 U and the optimum pH of immobilized enzyme was found to be 7.5, i.e., by 0.5 units higher than that of free enzyme (7.0). In contrast to the former case, urea decomposition occurred more slowly, which can be ascribed, dark colored cats
