In simple staining with a basic dye, do the gram-positive and gram-negative bacteria differ in retaining color?
Dmitriy789 [7]

Answer:

The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.

Explanation:

Stainings is a reagent or dye used to stain microscope specimens so as to make some structures visible.

Peptidogycan is a derivative polymer of glycan and peptides found in bacterial cell walls and varies in compositional concentration from species to species.

Cell wall- A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls). The cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and protecting the cell from damage.

There different types of staining techniques and classification based on the aim of the experiment and here is a few;

The etymology is from Gram + positive, is named after Dan ish bacteriologist Hans Christian Gram, who invented the Gram staining technique.

Used in bacteriology , bacteria that stains dark blue or violet after Gram staining, due to large quantities of peptidoglycan in the cell wall are gram positive.

And gram-negative bacteria is one that is not stained violet by Gram's method.

A spore is thick resistant particle produced by a bacterium or protist to survive in harsh or unfavorable conditions.

Spore staining (malachite green) however can be used to differentiate sporulating bacteria species.

The above shows the procedures of the Gram's staining method, The result and important of colour in differentiating the bacteria. A little insight into staining endospore.
