Dye for bacteriology.
In bacteriological diagnostics, Gram staining can be considered as one of the most important colorimetric methods. In the reaction, the aniline dyes are fixed on the basis of the subsequent action of iodine in bacterial cells.
The presence of lipoprotides, as components of the structure and therefore of the permeability of the cell wall, is of decisive importance.
According to this staining method it is possible to divide all bacteria into 2 groups (Gram +, Gram -).
In Gram positive containing lipoproteins it is no longer possible to dissolve the colored substance / iodine complex once formed, using bleaches such as Alcohol or Acetone: the cell remains blue-violet.
In Gram negative, ie bacteria that do not contain lipoproteins in the cell wall, it is possible to dissolve the complex by turning the color of the cell from pink to red.
