While lysozyme will break down the cell membrane of some gram positive bacteira, it does not affect all gram positives therefore it is not a suitable means of separating the two. Serial dilution would be a much more effective method.

Which linkage breaks lysozyme in bacterial cell wall?
Bacterial cell walls contain a layer of peptidoglycan, which is the specific site that lysozyme attacks.The layer contains alternating molecules called N-acetylglucosamine and N-acetylmuramic acid.These molecules form a strong chain that acts as the backbone for the cell wall. The link between the two is cleaved by lysozyme. Once this chain is broken by lysozyme, it results in bacterial death.
What is the functions of lysozyme in DNA extraction?
Usually DNA is obtained from bacterial cultures. To break the bacterial cell wall, there are several options (e.g., sonications, change in atmospheric pressure, etc.), however, there is another and milder method that many molecular biologists prefer in order to protect the DNA content the more possible, especially when the DNA that is wanted is related to plasmids. To do this, researchers uses the enzyme lysozyme in a coctail to digest cell walls, because lysozyme catalyzes the hydrolysis of polysaccharides that occur in the glycopeptide layer of bacterial cell walls. After lysozyme digestion, a mild detergent is added (e.g., SDS) to finish the cell wall breakdown.
Why are tears considered to be a nonspecific mechanism of the immune system?
Because tear contains lysozyme, an enzyme that destroys bacterial cell wall.
What is a outer supportive structure of a plant cell?
The cell wall supports and protects the plant cell.
What happens to a cell that has its peptidoglycan disrupted or removed?
It would rupture from internal pressure,with this cell wall incomplete or missing such cells have very little protection from lysis. Lysozyme an enzyme contained in tears in saliva, provides a natural defense against certain bacteria by hydrolyzing the bonds in glycan chains and causing the wall to break down.

How do tears fight against pathogens?
True A+

Because tear contains lysozyme, an enzyme that destroys bacterial cell wall.
How does EDTA enhance susceptibility of E. coli to lysozyme?
Divalent metals help stabilize the cell wall. By chelating (binding) these metals, EDTA weakens the overall structure and makes the cells more suceptible to lysis following lysozyme treatment.
Why does penicillin kill only actively multipling cells and lysozyme will kill cells in any stage of growth?
Penicillin inhibits transpeptidase, and enzyme that is necessary for bacterial cell wall synthesis. If a cell is not actively multiplying, then no cell wall synthesis is occurring and, therefore, penicillin does not inhibit the bacteria.
How do protoplast differ from L form?
Protoplasts are formed from gram-positive cells in the presence of lysozyme, which destroys the cell wall. L forms are gram-positive or gram-negative bacteria that do not make a cell wall. Therefore, L forms never had or made a cell wall as opposed to protoplasts which used to have a cell wall, but no longer do because it was destroyed. Penicillin can be used to destroy the cell wall of a bacterial gram-positive cell and form a protoplast, but in the presence of Penicillin, if a new bacterial cell is forming and cannot create a cell wall, then it will become an L form.
What is a outer supportive structure of a plant cell?
The cell wall supports and protects the plant cell.
What is the difference between ligase and lyase?
ligase mean to join..eg DNA ligase is used to join okazaki fragments ..&lyase mens to break down..lysozyme in our saliva & tears is lyase which disssolves bacterial cell wall
