In Vitro | Lysozyme is an ubiquitous enzyme. The hen egg is the most abundant source of lysozyme, which constitutes approximately 3.4% of the albumen proteins. Lysozyme is a natural antimicrobial that hydrolyzes the β(1-4) glycosidic linkage between N-acetylmuramic acid and N-acetylglucosamine found in the peptidoglycan layer of the bacterial cell wall and causing cell lysis. The bactericidal effect of lysozyme is primarily limited to gram-positive bacteria, including pathogens such as Listeria monocytogenes and certain Clostridium species as well as some spoilage organisms, including thermophilic spore-forming bacteria and certain yeasts. The gram-negative bacteria are more resistant to lysozyme action because of their complex cell wall structure[1]. |
Kinase Assay | For measurement of lytic activity in egg white at each pH, temperature, and CO2 condition, eggs are randomly selected from a flat of eggs (2 dozen eggs) obtained from a local grocery store. To determine the amount of egg white to be added to obtain a 0.001% lysozyme concentration, it is documented that chicken egg white contains approximately 3.4% lysozyme. For determining egg white activity, 0.030 g of albumen was added to 100 mL of the buffered solutions. This equated to a concentration of approximately 0.001% lysozyme. In addition, the egg white contains other antimicrobial proteins that are naturally present, as mentioned in the Introduction section[1]. |
