Methylene blue is used as an indicator for the presence of certain Ions such as the presence of HS - ion. spectrophotometry is used once the methylene blue has reacted to determine the quantity of said ion based on the intensity of blue that the reacion produces. Using a spectrophotometer you can determine the intensity and compare it with a set scale that has been calibrated with known concentrations of this ion.
Bile salts in Eosin Methylene Blue agar inhibit the growth of Gram-positive bacteria, allowing for the selective growth of Gram-negative bacteria. This helps in the detection and differentiation of organisms based on their ability to ferment lactose and produce acid.
because methylene blue turns colourless when it is reduced by hydrogen. during respiration hydrogen is produced and instead of reducing NAD, it reduces methylene blue and turns methylene blue colourless. if methylene blue goes from blue to colourless then this shows that the cell is respiring as it is producing a suffiecient amount of hydrogen to decolourise methylene blue
When you added methylene blue to the living yeast cell, the methylene blue is actually a dye so you could see the cells, therefore, the yeast cell became blue. It is much the same with hair dye. If you have a bottle of blue hair dye, it will dye your hair blue.
Methylene blue is necessary for various applications, such as in medical diagnostics, staining biological tissues, and as a medication to treat methemoglobinemia. It is also used as a redox indicator in chemical reactions and as a dye in various industries. In microscopy, methylene blue can help highlight cell structures for better visualization.
Methylene Blue, in this situation, is being used as a microscopy stain. Microscopy stains are used to allow for particular characteristics of cells to be observed in greater detail or to make them easier to see.

Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
One substance that has a similar function as methylene blue is crystal violet. It is commonly used in staining techniques for microbiological studies and exhibits similar properties in terms of staining cells and tissues.
If methylene blue is blue, it means that the compound is in its oxidized state (methylene blue) and has accepted electrons. Methylene blue can exist in both oxidized (blue) and reduced (colorless) forms depending on its redox state.
i think the methylene blue will be make aqua blue because the charcoal will penerate the color of methylene blue,,,there are absorption process,,,in the charoal between the methylene blue.... (kharlz)
Methylene blue stains everything blue.
Polychrome methylene blue is commonly used in histology to stain acidic polysaccharides, mucins, and cartilage sections. It helps differentiate structures and aids in the visualization of specific components within tissues under a microscope.

It's purpose is to make different types of cells clearer and easier- to -see when viewed closely.
