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.
Can you elimintate gram positive bacteria from a gram positive gram negative mixture with mild detergent treatment?
AnswerYou can use a "selective" medium that will inhibit the growth of Gram positive bacteria and only allow Gram negative bacteria to multiply. A medium which is commonly used for this is the McConkey agar which contains a crystal violet strain and allows only Gram negative cultures to grow.You can also eliminate Gram positive bacteria with antibiotics (e.g. ampicillin) provided that they are sensitive and not resistant.
How Can you elimintate gram positive bacteria from a gram positive gram negative mixture with mild detergent treatment?
as gram negative have low content of phospholipids than positive detergents at low concentration effectively kill negative bacteria
Why would you want to know if a gram stain is positive or negative?
Gram negative bacteria (pink gram stain) contain no outer cell membrane, while gram positive bacteria (purple gram stain) do contain an outer cell membrane. Gram negative and positive bacteria can respond differently to antibiotics. Many only work on only one of the two bacteria types. A gram stain is also the first step in identifying a bacteria, dividing bacteria into two large and distinct groups.
What is the difference between positive gram and negative gram?
The major difference between gram positive and the gram negative bacteria is the structure of their cell wall. The gram positive bacteria have two layers a plasma membrane and outer to it a peptidoglycan layer. But the gram negative bacteria have another layer other than the cell wall. While the gram negative bacteria has three layers. It has a plasma membrane that is called as the inner membrane, then a peptidoglycan layer and finally an outer membrane of phospholipids and lipopolysaccharides. There is space between the inner membrane and the peptidoglycan layer called as the periplasmic space. Peptidoclycan layer in the gram positive bacteria are much more thicker than that of the gram negative bacteria. The molecule teichoic acid is present in gram positive bacteria and the porin proteins are characteristically present in the gram negative bacteria. Gram positive bacteria usually produce exotoxins and the gram negative bacteria usually produces endotoxins. Gram positive bacteria gives Violet colour to the gram staining and the gram negative bacteria gives pink colour to the gram staining. In gram staining the bacteria is fixed on slides and then they are treated with Crystal Violet. After that they are treated with iodine and then they are decolourised. If the bacteria is gram negative then it shows Violet colour and if it is gram negative then it shows pink colour. Initially both strains show Violet colour after Crystal Violet treatment but on the treatment with iodine and decolourisation the gram negative bacteria loose colour and become pink. This is because in the gram positive bacteria the Violet crystals bind firmly to the peptidoglycan layer and the colour is not removed in later stages. In gram positive bacteria the colour does not penetrate much because of outer membrane and is lost much during decolourisation.

Do negative counters have the ability to eliminate creatures with indestructible?
No, negative counters do not have the ability to eliminate creatures with indestructible.
What is the appearance of Gram Negative bacteria after alcohol?
Gram Negative bacteria will appear pink or red after alcohol treatment in the Gram staining procedure due to the decolorization of the crystal violet dye. This is because the outer membrane of Gram Negative bacteria is disrupted by the alcohol, allowing the dye to be washed away.
Is klebsiella gram positive or negative?
i believe it is a gram bacteria which causes respiratory illness.
What is the difference between penicilin and streptomycin?
Peniciilin is derived from Penicillium chrysogenum and is active against Gram-positive bacteria. It connects peptidoglycan strands by irreversibly interacting with transpeptidase and prohibits the last cell wall synthesis. Streptomycin-sulfate is derived from Streptomyces griseusan and is an aminoglycoside antibiotic. It is active against Gram-negative bacteria and Mycobacteria and inhibits initiation of the protein biosynthesis. Penicillin and Streptomycin are often used together.
Does negative ion kills bacteria?
Negative ions supposedly kill some bacteria. There is some debate on how effective this is and how many negative ions you have to have circulating to kill bacteria.
What are the positive and negative aspects about bacteria?
The positive aspect about bacteria is that weak bacteria can be used to prevent or defend against other bacteria that harms the body which is the negative aspect of bacteria.
Which bacteria is catalase negative?
Enterococcus species are commonly catalase-negative bacteria.
Do gram negative bacteria possess lipopolysaccharides?
Yes, gram-negative bacteria possess lipopolysaccharides.
