Unlike Staphylococcus, Micrococcus has no teichoic acids in its cell wall. If you treated both bacteria with lysozyme, how will you expect their zones of inhibition to be different?

Answer #1

The staphylococcus species belongs to one of the few bacterial genera that are completely lysozyme resistant, which greatly contribute s to their persistence and success in colonizing the skin and mucosal areas of humans and animals. The exact mechanism of lysozyme resistance in staphylococcus species is unknown various possibilities are. (1)O-acetylation of the NAM of peptidoglycan.(2)attachment of other polymer eg.polysaccharides to the cell wall (3) a high degree of peptide cross linking. Lysozyme most frequently analysed by a variety of methods using micrococcus lysodeikticus cells as substrate. Lysozyme cleaves the p-(1)4) glycosidic bonds of the murien cell wall, which results in lysis of the bacterial cell.
