Lysozyme, a remarkable natural antimicrobial and antiviral enzyme, discovered by Alexander Fleming in 1921, when a droplet from Fleming’s nose (who was nursing a cold while working in his lab) accidentally fell into one of the Petri dishes containing microorganisms, noticing the bacteria reaction, Fleming set out to isolate it and find a dissolving bacterial protein, he named it lysozyme.
The invention of antibiotics can definitely be called human well-being in 1920s. Antibiotics are powerful medicines that fight bacterial infections. Used properly, antibiotics can save lives. They either kill bacteria or keep them from reproducing. However, with the need of development of production,the high degree of intensification in animal husbandry, nowadays gradually evolved into abuse of antibiotics. Seriously drug-resistance and drug-rusidue problems harmful to animal and human health. More and more people realize this problem and are being positive to pursue a new alternative of antibiotics.
Lysozyme (muramidase) came into people's horizons as a alternative of antibiotics. It is a naturally occurring enzyme found in bodily secretions such as tears, saliva, and milk. Scientists have discovered a large number of lysozyme from egg white which has a obviously effect on gram-positive bacteria, enterprises started industrialized production. Egg-white lysozyme has been used as an excellent preservative against many food spoiling microorganisms.
As a safe, high-efficiency bactericidal activity, experts began to aim at lysozyme application in animal husbandry, and achieved good results. But there is an obvious defect - it did not showed satisfactory on gram-negative bacteria.
Aegis Group‘s founder and chairman - Dr. Pan Hongtao, always pay special attention to animal & human health and lysozyme. He always believed that there must be a kind of lysozyme which both have good bactericidal activity on gram-positive and gram-negative bacteria. He led his R & D team devote to the lysozyme research for more than 15 years, and found a kind of microbial source one which is fermentated by genetic engineering & technology. Showed great bactericidal activity on gram-positive and gram negative bacteria, achieved replace antibiotics use in feed, reduce drug use, circumvent drug resistant problem, promote sustainable development of the livestock.
