FULLSAIL Lysozyme is a high-purity lysozyme chloride (E1105) extracted from hen egg white, widely recognized as safe (GRAS). It exerts strong hydrolytic activity against the cell walls of Gram-positive bacteria (e.g., Micrococcus luteus) by cleaving the β-1,4-glycosidic bonds between N-acetylmuramic acid and N-acetylglucosamine in peptidoglycan.
White powder, naturally derived from egg white, GRAS compliant
Enzyme activity 2,000–20,000 U/mg (tailored to requirements)
Excellent thermal stability under acidic conditions (pH 4–6.5); optimum temperature 35℃
Soluble in water (10 mg/mL)
Effective against a broad spectrum of Gram-positive bacteria
Complies with FCC IV, JECFA and EU Regulation (E 1105)
