Comparative Investigation of Alternative Negative Staining. A bacterial staining method using fluorescent dye is a popular tool, although the weakness of fluorescence intensity and its fading over time constitute notable drawbacks. in the process of esterase-active bacteria staining with carboxyfluorescein diacetate (cfda),, membranes, cell wall and surface appendages to name the general structures, and polymers that make up bacterial cell walls to explain the differences between gram negative and gram positive cells to describe the chemical composition, function and serological classification as h antigen of bacterial flagella and how they differ from flagella of eucaryotic cells to describe the chemical.

About the characteristics of the cell wall (thickness). gram staining (or gram’s gram staining (or gram’s method) is an emprical method of differentiating bacterial species into two large staining and how it differentiates bacteria on the basis of their cell wall structure should also be included (1 point). the purpose and objectives of the experiment should be stated and a …

Staining; and 3) will retain the original cell morphology after fixation and staining. after you have stained your bacterial smears, you will examine them with the oil immersion lens, noting the morphological and staining characteristics of each species. decolorizing the cell causes this thick cell wall to dehydrate and shrink, which closes the pores in the cell wall and prevents the stain from exiting the cell. so the ethanol cannot remove the crystal violet-iodine complex that is bound to the thick layer of peptidoglycan of gram positive bacteria and appears blue or purple in colour.

Gram staining differentiates bacteria by the chemical and physical properties of their cell walls by detecting the properties of peptidoglycan. gram staining method is useful in differentiating majority of bacterial species into two broad categories. even though all bacterial species cannot be differentiated based on gram staining technique, this method has immense application in clinical.

    Gram stain is commonly used to assist in bacterial identification. this stain, first developed in 1884, separates bacteria into groups, depending on their reaction to this stain. bacteria react by testing gram-positive, gram-negative, gram-variable, with the first two groups being the most common. the response of cells to the stain is due to differences in their cell walls. cell walls of gram size of bacteria • unit of measurement in bacteriology is the micron (micrometre, µm) • bacteria of medical importance (0.2 – 1.5 µm) in diameter (3
