The lysosome erodes the peptidoglycan layer of Gram-positive cells. The peptidoglycan layer is very thick on Gram-positive cells and once it has been destroyed there is no cell wall for the bacteria. Because of this when osmosis occurs (water is moving out of the lysosome solution with high water potential to the bacteria with a lower water potential) the cell Autolyses. In other words it bursts because it has no way to prevent water overfilling it and bursting it's cell walls. Therefore the liquid becomes clear as there aren't any cells filling it. This doesn't happen in Gram-Neagtive bacteria as they have a lipid layer. When their thiner Peptidoglycan layer has been eroded, the lipid prevents cell bursting thus the solution remains turbid. Hope this helps :)

What will happen when a gram positive bacterium is placed in a aqueous solution of lysozyme and 10 percent sucrose?

The lysozyme will break down the peptidoglycan layer of the gram positive bacterium, causing it to lose its structural integrity and burst. The presence of sucrose will create a hypertonic environment, leading to osmotic dehydration of the bacterium due to water moving out of the cell, adding to its demise.


Can treatment with Transpeptidase eliminate gram positive bacteria from a mixture of gram positive bacteria and gram negative bacteria?

No. A treatment of ethylenediaminetetraacetic acid (EDTA) and the enzyme, lysozyme, will cause gram negative bacteria to lyse. Some gram positive bacteria can also be lysed by doing this. The EDTA stabilizes the solution and allows lysozyme to cut the bonds between the carbohydrates that make up the cell wall wall in bacteria. This will lyse the cell and cause the contents of the cell to be spilled out. This technique is primarily used for DNA assays. A good way to isolate either gram positive or gram negative is by using different types of agar. The MacConkey agarmight be the most useful for what you want to do. It will only allow gram negative to grow, isolating just the gram negatives only.


What does lysozyme in saliva do?

Lysozyme, also known as muramidase or N-acetylmuramide glycanhydrolase, are a family of enzymes which damage bacterial cell walls by catalyzing hydrolysis of 1, 4-beta-linkages between N-acetylmuramic. Lysozyme is abundant in a number of secretions, such as tears, saliva, human milk and mucus. It is also present in cytoplasmic granules of the polymorph nuclear neutrophils (PMN). Large amounts of lysozyme can be found in egg white. The enzyme functions by attacking peptidoglycans (found in the cell walls of bacteria, especially Gram-positive bacteria) and hydrolyzing the glycosidic bond that connects N-acetylmuramic acid with the fourth carbon atom of N-acetyl glucosamine.

Is gram-positive cell wall sensitive to lysozyme?

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 enzyme in tears kills germs?

Your tears contain the enzyme lysozyme. This enzyme acts by disrupting the cell-walls of gram-positive bacteria by digesting the peptidoglycan in them, thereby preventing infection. This enzyme is also found in your saliva and is an example of a non-specific immune response.

The pI of a lysozyme is 11. What is the pH range in which the overall charge of the lysozyme is positive?

At pH values less than the pI point the net charge is positive. If at pH above the pI poiint, the charge will be negative.

What is the functions of lysozyme in DNA extraction?

Lysozyme helps break down bacterial cell walls during DNA extraction, allowing for the release of DNA from the bacterial cells. This enzyme is particularly helpful in isolating DNA from gram-positive bacteria, which have thicker cell walls compared to gram-negative bacteria.
