Methylene blue is a chemical compound used in the treatment of multiple medical issues. However, it's mostly known in school labs as a dye for microscopic slides, to make the object being viewed more visible.
Methylene blue reduction is the method used to measure the bacterial density in milk. The test is evaluated in term of the amount of time required from introduction of the blue until the milk turns white.
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
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.
Methylene blue is used to stain animal cells, such as human cheek cells, to make their nuclei more observable. Also used to staining the blood film and used in cytology. It gives a blue coloration to the human cheek cell.
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.
Polluted water sample will decolorize the methylene blue solution faster than a pure water sample.
Adding methylene blue to sugar water solution.
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)
NADH
you can get methylene blue powder from a scientific store, it comes in powdered form. its pretty soluble in water and alcohol etc. the stain is made by dissolving an appropriate amount on methylene blue in a solvent, e.g for 0.1 dissolve 0.1% gram of methylene blue in 100 gram water, for 9% dissolve 9 grams
Methylene blue is a cationic dye, meaning it has a positive charge in solution. This positive charge allows it to bind effectively to negatively charged components, such as nucleic acids and proteins, making it useful in various biological and staining applications. In acidic or neutral pH conditions, methylene blue remains positively charged, contributing to its effectiveness as a dye.
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.
Methylene blue stains everything blue.

A blue solution can be formed by substances that absorb light in the red/yellow part of the spectrum, allowing blue light to be transmitted or reflected. Copper sulfate, methylene blue, and cobalt chloride are examples of compounds that can form blue solutions.
