Regulation
Purpose It is used to show Gram (+) and Gram (-) bacteria by light microscopy.
Working Principle Gram-Positive/Negative status is a characteristic that depends on the cell wall (peptidoglycan) structure of bacteria. The peptidoglycan structure of Gram-Negative bacteria is thinner shaped between the outer membrane and the inner membrane than Gram-Positive bacteria. In gram-positive bacteria, thick peptidoglycan has the property of retaining crystal purple. Lugol ensures that the paint is retained. Gram-positive bacteria have less cell wall permeability. Therefore, they do not release dyes during decolorization with denatured alcohol. In gram-negative bacteria, alcohol dissolves lipids in the outer membrane, the pores open and the crystalline purple dissipates. In this way, Gram-negative bacteria are stained with fuchsin, which is then added to the medium.
Warnings, Precautions, Recommendations It is very flammable liquid and vapor. It leads to serious eye irritation. There is a suspicion of causing cancer. Keep away from heat/ sparks/flames/hot surfaces. Use protective gloves/ protective clothing/ eye protection/ face protection. In case of skin contact: Remove/Remove all contaminated clothing immediately. Dry your skin with water/ shower. In case of eye contact: Dry carefully with water for a few minutes. If it is attached and easy to do, remove the contact lenses. Keep rinsing. IF it is in case of exposure or interaction: Get medical help/care. Keep it under lock and key.
