Abstract：At present, the side effect caused by misuse of antibiotic becomes more and more serious, seeking effective alternatives for antibiotics is particularly urgent. Lysozyme is able to catalyze the hydrolysis of β-1,4-glycosidic bonds between the N-acetylglucosamine and N-acetylmuramic acid in the peptidoglycan layer of bacterial cell walls. It functions as bacteria digestion and decomposition, and exogenous microbial growth inhibition, and immunity enhancement. Lysozyme is widespread in animals especially in the ruminant in vivo. In this paper, we summarized recent research progresses on lysozyme with the focus on origin and distribution, gene sequence, protein structure and the enzymological characteristics, the biological functions and activities of lysozymes, and discussed its acid resistance. Meanwhile, the evolution of lysozyme in ruminant was also discussed. Finally, we suggested perspectives of lysozyme. It’s very significant to research the lysozyme in ruminant for its underlying role to understand the basic knowledge and to probably application in the production.
