Description

Lysozyme is a naturally occurring enzyme, also known as muramidase, which catalyzes the hydrolysis of 1,4-β-linkages in bacterial cell wall peptidoglycans. This potent antimicrobial action makes it a critical ingredient for applications requiring natural preservation and bacterial control. It is widely utilized across the pharmaceutical, food and beverage, and biotechnology industries as a preservative, a research tool, and a therapeutic agent.

Application

• Pharmaceutical Manufacturing: Used as an active pharmaceutical ingredient (API) in throat lozenges, nasal sprays, and eye drops for its antibacterial and anti-inflammatory properties.
• Food & Beverage Preservation: Employed as a natural preservative in cheese, wine, beer, and other perishable foods to inhibit spoilage bacteria like *Listeria*.
• Biotechnology & Research: Essential reagent for cell lysis procedures in molecular biology, microbiology, and protein purification workflows.
• Infant Formula & Nutraceuticals: Added to infant formula and dietary supplements to mimic the immune-boosting properties found in human breast milk.
• Cosmetics & Personal Care: Incorporated into oral care products (toothpaste, mouthwash) and skincare formulations for its antibacterial benefits.
• Diagnostic Kits: Used as a component in certain diagnostic assays and kits for bacterial detection and analysis.
