Industrial Applications of Urease
| Industry | Application | Process |
|---|---|---|
| Medical Diagnostics | Detection of urea concentration in urine or blood to support diagnosis of renal function and Helicobacter pylori infection | Enzymatic assay: Urease catalyzes urea hydrolysis into ammonia and carbon dioxide; urea concentration is determined via pH change or ammonia quantification |
| Agriculture | Study of soil nitrogen cycling and assessment of fertilizer utilization efficiency | Urease is added to soil samples to measure urea hydrolysis rate, thereby evaluating soil microbial activity and nitrogen release potential |
| Food Industry | Reduction of urea content in fermented foods (e.g., soy sauce, fermented bean paste) to minimize formation of carcinogenic ethyl carbamate from the reaction between ethanol and urea | Urease is added prior to or during fermentation to degrade urea present in raw materials |
| Environmental Monitoring | Monitoring biodegradability of urea-containing wastewater in wastewater treatment | Urease activity is used to assess microbial capacity for urea degradation, enabling optimization of biological treatment processes |
| Biotechnology | Use as a tool enzyme in molecular biology assays and biosensor development | Immobilized urease is employed to construct urea-detecting electrodes or sensing elements in microfluidic chips |
Manufacturing Quality Control of Urease
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzyme Activity (U/mg protein) | Spectrophotometric Urease Assay (UV-Vis) | Measures ammonia release from urea hydrolysis at 625 nm using phenol-hypochlorite reaction; activity calculated from standard ammonia curve. |
| Protein Content | Lowry or Bradford Assay (UV-Vis) | Quantifies total protein via colorimetric detection of peptide bonds (Lowry) or dye-binding to basic amino acids (Bradford). |
| Purity (SDS-PAGE Purity) | SDS-Polyacrylamide Gel Electrophoresis (SDS-PAGE) | Resolves protein subunits by molecular weight under denaturing conditions; purity estimated from band intensity of target ~100 kDa dimer. |
| Heavy Metals (Pb, Cd, Hg, As) | ICP-MS or ICP-OES | Quantifies trace metal impurities after acid digestion by detecting element-specific ion signals (ICP-MS) or atomic emission lines (ICP-OES). |
| Residual Solvents (e.g., acetone, ethanol) | Gas Chromatography (GC-FID) | Separates and quantifies volatile organic solvents using flame ionization detection based on retention time and peak area calibration. |
| Moisture Content | Karl Fischer Titration | Determines water content via stoichiometric iodine–sulfur dioxide reaction in anhydrous methanol/pyridine medium. |
| pH (1% w/v aqueous solution) | Potentiometric pH Measurement | Measures hydrogen ion activity in a standardized suspension using calibrated glass electrode and reference electrode. |
| Microbial Contamination (Total Aerobic Count) | Membrane Filtration / Plate Count Agar Culture | Quantifies viable aerobic microorganisms by filtration, membrane transfer to nutrient agar, and colony enumeration after incubation. |
| Endotoxin Level | Limulus Amebocyte Lysate (LAL) Assay (Turbidimetric or Chromogenic) | Detects bacterial endotoxins via coagulation cascade activation in horseshoe crab lysate, measured as turbidity or p-nitroaniline release. |
| Specific Absorbance (A280/A405) | UV-Vis Spectrophotometry | Assesses purity and absence of heme contamination by ratio of absorbance at 280 nm (protein/aromatics) and 405 nm (heme/hemoprotein impurities). |
