Are archaebacteria gram positive or gram negative?

Archaebacteria are neither gram positive nor gram negative because they do not have peptidoglycan in their cell walls like bacteria. Instead, they have unique cell wall structures that make them distinct from both gram positive and gram negative bacteria.


What is a gram variable bacteria?

A gram variable bacteria is a type of bacterium that does not consistently stain as either gram-positive or gram-negative. This variability can make it challenging to identify using traditional Gram staining techniques.


Function of Gram's iodine?

Iodine is used as a mordant in the gram staining procedure to make large crystals when it is used with crystal violet dye. In gram positive cell walls those crystals get stuck and wont get washed off with the alcohol. In gram negative cell walls the crystals are washed out.


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.

Construct a Venn diagram to illustrate the similarities and differences between gram positive gram negative cells?

Not really possible to make a venn diagram, but here's a list: Similarities: In Bacteria Involve a peptidoglycan layer Differences Gram-negative is much more toxic Gram-negative is crystal violet in the Gram stain while Gram-positive is red


What is gram variability?

Gram variability refers to a characteristic of certain bacteria that can exhibit variability in their response to Gram staining, appearing as a mix of both Gram-positive and Gram-negative characteristics. This variability can make the identification of these bacteria challenging because their staining characteristics may not be consistent.


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.


Was Louis Pasteur the first to produce endospores?

No, Louis Pasteur did not discover endospores. The Russian scientist Ferdinand Cohn is credited with first describing endospores in the 19th century. Pastuer did, however, make significant contributions to the field of microbiology and germ theory.


Are methanogens gram positive?

Most are not. Gram positive archaea have a thick, single cell membrane. Gram negative archaea have two thinner membranes with a region in between them called the periplasm. The periplasm make make up 40% of certain archaea bacteria. The illustrated mechanisms of methanogen metabolism all require a membrane across which a Na+ and H+ chemical-electric gradient can be produced. This is not possible in gram positive archaea.There may be another mechanism of metabolism which yields methane. Those methanogens that make use of the substrates H2+CO2, formate, methanol, methylamines and acetate are all gram negative.
