Industrial Applications of Lysozyme
| Industry | Application | Process |
|---|---|---|
| Food Industry | Food preservation and freshness maintenance | Lysozyme hydrolyzes bacterial cell walls and is applied in the preservation of dairy products, meat products, and other food items |
| Pharmaceutical Industry | Antibacterial agent | Used as a natural antibacterial agent for treating bacterial infections or as an adjunctive therapeutic agent |
| Biotechnology | Research tool | Applied in studies of cell wall structure and bacterial physiological properties |
| Cosmetics Industry | Antimicrobial additive | Incorporated into skincare formulations to inhibit the growth of harmful microorganisms |
| Agriculture | Preservation and freshness maintenance | Applied in post-harvest treatment of fruits, vegetables, and other agricultural produce |
| Laboratory | Cell disruption | Used to remove bacterial cell walls for intracellular component extraction |
Manufacturing Quality Control of Lysozyme
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Enzymatic Activity | Spectrophotometric Assay (Lysozyme Activity Assay) | Measures rate of Micrococcus lysodeikticus cell wall lysis at 450 nm by monitoring decrease in turbidity. |
| Protein Content | UV-Vis Spectrophotometry (A280) | Quantifies protein concentration based on absorbance at 280 nm using extinction coefficient (E1cm,1% = 22.8). |
| Purity (by SDS-PAGE) | Sodium Dodecyl Sulfate Polyacrylamide Gel Electrophoresis | Resolves protein bands under denaturing conditions; purity assessed by intensity and number of bands relative to main lysozyme band. |
| Residual Moisture | Karl Fischer Titration | Determines water content via coulometric or volumetric titration using iodine-based redox reaction. |
| pH | Potentiometric Measurement (pH Meter) | Measures hydrogen ion activity in aqueous solution using calibrated glass electrode. |
| Heavy Metals | ICP-OES | Quantifies trace metal impurities (e.g., Pb, Cd, As, Hg) by atomic emission after acid digestion and plasma excitation. |
| Residual Solvents | Gas Chromatography (GC-FID) | Separates and quantifies organic solvents (e.g., ethanol, acetone) using flame ionization detection. |
| Endotoxin Level | Limulus Amebocyte Lysate (LAL) Assay | Detects bacterial endotoxins via enzymatic cascade leading to gel formation or colorimetric signal. |
| Microbial Contamination | Membrane Filtration and Plate Count | Enumerates viable aerobic microorganisms by filtration, membrane transfer to agar, and colony counting after incubation. |
| Particle Content | Light Obscuration Particle Counting | Counts and sizes suspended particles in solution by measuring light blockage as particles pass through laser beam. |
| Specific Optical Rotation | Polarimetry | Measures rotation of plane-polarized light induced by chiral molecules in solution at specified wavelength and temperature. |
| Residual Host Cell Proteins | ELISA | Quantifies host cell protein impurities using antibody-based capture and enzymatic colorimetric detection. |
