The crystal violet method and the Schaeffer-Fulton method
Negative staining has a dark contrasted background and the bacteria is white. Simple staining has a white background and bacteria is the color depended on your stain color.Negative staining when prepared is NOT heat fixed but simple staining when prepared is heat fixed. Heat fixed means when preparing slide with bacteria on it, it is passed over some type of flame, like a Bunsen burner flame, three times or four times.
The heat-based staining procedure is called heat fixation. In this process, heat is used to adhere the specimen to the slide, allowing it to withstand the subsequent staining and washing steps without washing away.
which stain is used to colour chromosomes
Iodine stain is commonly used to detect amyloplasts due to their ability to stain starch granules purple-black.
Heat is the mordant used in the spore stain, it fixes the primary stain.
Yes, a mordant is used in the acid-fast stain technique. The mordant used is heat to help drive the primary stain, usually carbol-fuchsin, into acid-fast bacteria, such as Mycobacterium species, which resist decolorization with acid-alcohol.
Depends if heat is used
Since there is no heat fixing or strong cemicals are used the bacteria are less distorted
The crystal violet method and the Schaeffer-Fulton method
Both endospore stain and acid-fast stain are special staining techniques used to identify specific types of bacteria. Endospore stain is used to detect the presence of endospores in bacterial cells, while acid-fast stain is used to identify bacteria that have a waxy lipid layer in their cell wall, such as Mycobacterium species. Both stains involve the use of specific dyes and heat to penetrate and stain the bacterial structures of interest.

It acts as the mordant to soften the mycolic acid so that the stain can penetrate the cell.
The heat is used to drive the primary stain, carbol fuchsin, into the waxy cell wall of acid-fast bacteria. This allows the stain to penetrate the mycolic acid in the cell wall, making the bacteria resistant to decolorization with acid-alcohol.
