Is alcohol acetone a decolorizer? Either acetone or ethyl alcohol can be used as the decolorizing agent. The alcohol dissolves lipids found in the outer cell membrane of Gram-negative bacteria, allowing the crystal violet-iodine complex to leak out of the thinner peptidoglycan layer.
What is the Decolorizer in the Gram stain? The decolorizer, ethyl alcohol, is the most crtitical step. Ethyl alcohol is a nonpolar solvent, and thus penetrates the cell walls of Gram negative cells more readily and removes the crystal violet-iodine complex.
What is the purpose of acetone alcohol in Gram stain? A decolorizer such as ethyl alcohol or acetone is added to the sample, which dehydrates the peptidoglycan layer, shrinking and tightening it. The large crystal violet-iodine complex is not able to penetrate this tightened peptidoglycan layer, and is thus trapped in the cell in Gram positive bacteria.
Can methanol be used as Decolorizer? that the speed of decolorization by an alcohol varies inversely to its molecular weight. Thus methanol decolorizes more rapidly than ethanol and the propyl alcohols more slowly. Of these alcohols, methanol and isopropyl alcohol are commercially available and of course are not affected by the Volstead act.
