If it has a use by date you are supposed to observe that date. I personally would ignore the use by date and use it
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 is an example.
Methylene blue is helpful to observe cells through a violet-blue color, making organelles, as well as the cell, easier to identify.
Active enzymes within living cells cause methylene blue to become colorless. Since dead yeast cells have inactive/denatured enzymes, the methylene blue stays blue.
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
Methylene blue stains everything blue.
Methylene blue can inhibit the growth and reproduction of paramecium by disrupting cellular respiration and other metabolic processes. It interferes with the electron transport chain in mitochondria, affecting energy production in the cell and ultimately leading to its death.
METHYLENE BLUE has high molecular weight.

Methylene blue is a synthetic dye that appears as a dark blue or greenish-blue color in its solid form. It is commonly used in biological staining techniques and as a medication for certain medical conditions.
Nope - methylene blue is a stain. You need liquid indicator like phenolphthalein that responds to pH changes.

The pH of the methylene blue stain can impact its ability to adhere to bacteria and penetrate the cell wall. A lower pH may enhance staining by increasing the positive charge of the dye, allowing it to bind more effectively to the negatively charged bacterial cell wall components. Conversely, a higher pH could reduce the staining efficiency by decreasing the positive charge of the dye.
