Lysozyme is a glycosidic hydrolase extracted from egg white and refined by microfiltration, ultrafiltration and vacuum freeze-drying technology, which is a single peptide chain composed of 18 kinds of 129 amino acid residues with a molecular weight of about 14000a. It can dissolve the cell wall of Gram-positive bacteria and play the role of sterilization, and is widely used in food preservation, pharmaceutical processing, scientific research experiments and other fields.
Soluble in water, aqueous solution is clear liquid, insoluble in ether and acetone

Product specification: 10,000-45,000 FIPU/mg (can be customized) Product properties: white to light yellow powder Storage: room temperature dry and protected from light Shelf life: 12 months
1、Corrosion and preservation
By decomposing bacterial cell wall, lysozyme has a decomposing effect on Gram-positive bacteria such as Bacillus subtilis and Radiation-resistant Micrococcus, and also has a definite degree of lysis effect on Gram-negative bacteria such as Escherichia coli, common Aspergillus and Vibrio parahaemolyticus. It has no adverse effect on human cells without cell wall, and is widely used in preserving aquatic products, meat, cakes, sake, wine and beverages.
Adding a certain amount of lysozyme to fresh milk or milk powder not only has the effect of preserving freshness, but also can kill intestinal spoilage cocci, increase the anti-infection power of intestine, promote the proliferation of intestinal bifidobacteria and lactic acid bacteria, thus promoting the digestion and utilization of casein, which is often used in the addition of infant dairy products and food.
Lysozyme, as a non-specific immune factor existing in normal body fluids and tissues, can be used as a natural anti-infective substance with bactericidal effect, which has the functions of antibacterial, antiviral, hemostatic, anti-swelling and pain relief, and accelerating tissue recovery. It is used clinically for chronic rhinitis, acute and chronic pharyngitis, oral ulcers, chickenpox, herpes zoster and flat warts. It can also be used in combination with antibacterial drugs to treat various bacterial and viral infections.
4、Daily chemical industry
The sterilization principle of lysozyme is safe, non-toxic and harmless to human body. It can be added into facial mask and skin care products, which can play the role of antibacterial and freshness, as well as anti-inflammatory effect on skin. Added to toothpaste, it can promote the role of swelling and recovery for swollen gums.
Lysozyme has the function of destroying the structure of bacterial cell wall, and the enzyme is used to treat G+ bacteria to get protoplasm, therefore, lysozyme is an essential tool enzyme for cell fusion operation in genetic engineering and cell engineering.
