Describe the basis of the gram

Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents the gram stain procedure distinguishes between gram positive and gram negative groups by coloring these cells red or violet. The gram stain procedure enables bacteria to retain color of the stains, based on the differences in the chemical and physical properties of the cell wall 1 gram positive bacteria: stain dark purple due to retaining the primary dye called crystal violet in the cell wall example: staphylococcus aureus fig: gram positive bacteria 2. Gram stain or gram staining, also called gram's method, is a method of staining used to distinguish and classify bacterial species into two large groups (gram-positive and gram-negative) the name comes from the danish bacteriologist hans christian gram , who developed the technique.

describe the basis of the gram Ex 4: gram stain study guide by vanessa_emerah includes 10 questions covering vocabulary, terms and more  on the basis of gram-stain reaction, can you distinguish species of:  describe at least two conditions in which an organism might stain gram variable.

-gram pos look like a dark blue/purple colour, and gram neg look red a mixture of nutrients such as proteins, carbs, minerals, vitamins, and moisture in the right composition is called -culture medium (plural, media) it may be prepared in liquid form, as a broth or solidified with agar.

The gram stain is a technique devised to categorise most bacteria into two sub-categories gram positive and gram negative, based on the properties of the cell wall we will write a custom essay sample on describe the basis of [. The iodine in gram stain fixes the crystal violet to the bacterial cell wall of the gram positive bacteria what is the purpose of the alcohol solution in the gram stain the alcohol serves to dehydrate the peptitoglycan layer of the cell wall. The gram stain 2 describe the different types of bacteria 3 discuss bacterial structure and the function of the different bacterial components 4 discuss the distinguishing characteristics of gram positive and gram negative bacteria for this lecture you should focus on the major concepts and not on the names of the different bacteria. Gram-negative cells have thin layers of peptidoglycan, one to three layers deep with a slightly different structure than the peptidoglycan of gram-positive cells with ethanol treatment, gram-negative cell walls become leaky and allow the large cv-i complexes to be washed from the cell.

Introduction gram staining is a procedure founded by christian jacobs hans gram in 1883 in germany the gram stain is a technique devised to categorise most bacteria into two sub-categories gram positive and gram negative, based on the properties of the cell wall. Describe the basis of the gram stain introduction gram staining is a procedure founded by christian jacobs hans gram in 1883 in germany the gram stain is a technique devised to categorise most bacteria into two sub-categories gram positive and gram negative, based on the properties of the cell wall. Differences between gram positive and gram negative bacteria coz its very difficult todistinguished between this two gram bacteria on the basis of this grahm staning coz the colour seems same as pinkband violeti think other innovative distinguishing colour should be prepared differences between gram positive and gram negative bacteria.

The gram stain is a basic differential stain used to determine if a bacterial cell is gram positive or negative gram positive cells have a thick peptidoglycan layer that will trap the crystal violet iodine crystals and appear purple. Gram-positive cells in gram-positive bacteria , peptidoglycan makes up as much as 90% of the thick cell wall enclosing the plasma membrane see page 2 for a diagram of the gram-negative cell wall and a video on. Amount and location of peptidoglycan in the prokaryotic cell wall determines if a bacterium is gram-positive or gram-negative photos and video.

Gram staining is a common technique used to differentiate two large groups of bacteria based on their different cell wall constituents the gram stain procedure distinguishes between gram positive and gram negative groups by coloring these cells red or violet gram positive bacteria stain violet due. Describe the molecular basis behind gram staining what part of the bacteria is stained with the primary stain, what part is stained with the counter stain why do we wash alcohol over the slide before the counter stain 18 describe in great detail the steps in performing a gram stain include incubation times.

The gram stain 2 describe the different types of bacteria 3 discuss bacterial structure and the function of the different bacterial components gram stain and bacterial morphology: of all the different classification systems, the growth requirements: microorganisms can be grouped on the basis of their need for oxygen to grow.
