Gram positive bacteria have a thick peptidoglycan layer and no outer lipid membrane whilst Gram negative bacteria have a thin peptidoglycan layer and have an outer lipid membrane. As Gram positive bacteria lack an outer lipid membrane, when correctly referring to their structure rather than staining properties, are termed monoderms. The gram-positive bacteria retain the crystal violet and stain purple, while the Gram-negative bacteria lose the crystal violet and stain red from the safranin counterstain. So by Gram-staining technique and the color they retain is crystal violet or not describes the features of the bacteria, as well they are characterized as positive or negative.

The gram-positive bacteria retain the crystal violet and stain purple, while the Gram-negative bacteria lose the crystal violet and stain red from the safranin counterstain. So by Gram-staining technique and the color they retain is crystal violet or not describes the features of the bacteria, as well they are characterized as positive or negative. Present in both; in gram negative bacteria, the peptidoglycan layer is thin, while those in gram positive is thick. Periplasmic Space Both gram-negative and gram-positive contain this. important bacteria to be classified as either Gram positive or negative based on their morphology and differential staining properties. Slides are sequentially stained with crystal violet, iodine, then destained with alcohol and counter-stained with safranin. Gram positive bacteria stain blue-purple and Gram negative bacteria stain red. The Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample,

These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production. Comparison chart. Gram-

Some bacteria such as Deinococcus, which stain gram-positive due to the presence of a thick peptidoglycan layer, but also possess an outer cell membrane are suggested as intermediates in the transition between monoderm (gram-positive) and diderm (gram-negative) bacteria.
