the cell wall contains mycolic acid. a dye (carbol fuchsin) is applied to the culture, then washed with acid-alcohol. those cells with mycolic acid in their cell wall will retain the dye even after the alcohol rinse. but those cells without mycolic acid will release the dye.
Mycolic acids are responsible for the acid-fast property of mycobacteria. They are long-chain fatty acids found in the cell walls of mycobacteria, such as Mycobacterium tuberculosis, which makes them resistant to staining by conventional methods.

Which chemical agents is fairly effective against endospores and mycobacteria?
One chemical agent that is fairly effective against endospores and mycobacteria is hydrogen peroxide. It is a powerful oxidizing agent that can disrupt the cell walls and membranes of these microorganisms, leading to their inactivation. Other chemical agents such as chlorine dioxide and peracetic acid can also be effective against endospores and mycobacteria.
Is Hydrofluoric acid reacts with glass an example of chemical property?
This is a chemical reaction (dito change).
M smegmatis acid fast?
Mycobacterium smegmatis is a fast-growing species of mycobacteria, but it is not acid-fast like the pathogenic mycobacteria such as Mycobacterium tuberculosis. Acid-fast staining is a characteristic feature of mycobacteria that have a waxy lipid layer in their cell wall, which makes them resistant to staining by conventional methods.
Is a reaction with acid to form hydrogen a physical property?
Reactivity is a chemical property (in chemistry !).No, it is a chemical property. Reactivity is always a chemical property, because when a substance reacts with another, you will get a chemical change and some new form of matter. Baking soda, for instance, will react chemically with vinegar to produce new forms of matter; namely water, carbon dioxide, and sodium acetate.
Is the corrosive action of acid rain on granite a physical property?
The corrosive action of acid rain on granite is a chemical property. It involves a chemical reaction between the acid in the rain and the minerals in the granite, leading to its deterioration over time. This reaction changes the chemical composition of the granite, making it a chemical property.
Is a react with acid a chemical or a physical property?
Chemical property because acid is a chemical
Is Reacts with an acid a Physical Property or Chemical Property?
Reacting with an acid is a chemical property because it involves a change in the chemical composition of the substance.
Which chemical agents is fairly effective against endospores and mycobacteria?
One chemical agent that is fairly effective against endospores and mycobacteria is hydrogen peroxide. It is a powerful oxidizing agent that can disrupt the cell walls and membranes of these microorganisms, leading to their inactivation. Other chemical agents such as chlorine dioxide and peracetic acid can also be effective against endospores and mycobacteria.
Reacts with acid chemical or physical property?
Chemical property: Reacts with acid to form a salt and water through a neutralization reaction. Physical property: Acid-base indicators change color in the presence of an acid.
Is reacts with acid physical property or chemical property?
it is chemical change
Is ability to react to acid a chemical or physical?
The ability to react to acid is a chemical property because it involves a substance's chemical composition changing when it comes into contact with an acid.
Is something that can neutralize an acid a physical of a chemical property?
The ability to neutralize an acid is a chemical property, as it involves a reaction between the acid and the neutralizing agent to form new substances with different properties.
Is reacting with with acid a physical property?
It is a chemical property.
Is neutralizes an acid chemical property or physical?
Chemical
When an object reacts with acid to form hydrogen is it a chemical or physical property?
It is a Chemical property.
Is Hydrofluoric acid reacts with glass an example of chemical property?
This is a chemical reaction (dito change).
Is neutralizes an acid a chemical or physical property?
