It is blue, like its name.
the ph of the stain on the bacteria caused by methylene blue would not affect it a lot since all methylene blue is supposed to do is make it visible on the microscope for e.g.
A general term for a chemical that makes a specimen visible is a stain. There are many types of stains available, depending upon the structure you want to visualize and the type of microscope you want to use, e.g. fluorescent stains like DAPI for fluorescence microscopy, or hematoxylin and eosin (H and E) staining for brightfield microscopy.Immersion oil
# The pH will determine if the bacteria will have a particular charge. If the chromophore is a positive ion like the methylene blue in the equation shown in the reading, the stain is considered a basic stain; if it is a negative ion, it is an acidic stain. Most bacteria are stained when a basic stain permeates the cell wall and adheres by weak ionic bonds to the negative charges of the bacterial cell.
The methylene blue reduction test is based on the fact that the color imparted to milk by the addition of a dye such as methylene blue will disappear more or less quickly. The removal of the oxygen from milk and the formation of reducing substances during bacterial metabolism causes the color to disappear. The agencies responsible for the oxygen consumption are the bacteria. Though certain species of bacteria have considerably more influence than others, it is generally assumed that the greater the number of bacteria in milk, the quicker will the oxygen be consumed, and in turn the sooner will the color disappear. Thus, the time of reduction is taken as a measure of the number of organisms in milk although actually it is likely that it is more truly a measure of the total metabolic reactions proceeding at the cell surface of the bacteria.
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.
Methylene blue is helpful to observe cells through a violet-blue color, making organelles, as well as the cell, easier to identify.
The "methyl" and "methylene" come from their chemical structures. Something that has "methyl" in its name contains a methyl group - CH3. A common chemical like this is methyl alcohol - CH3OH. The methylene group is CH2. The blue and violet? That's what color they are.
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
The methylene blue will make the paramecium very horny and secrete sperm.
METHYLENE BLUE has high molecular weight.
To make the Eosin Methylene BLue Agar look cool and hip.
Methylene blue is an example.
The blue color is a result.of oxidation of the color indicator. Blue means there's oxygen present. Colorless means there's an absence of oxygen.
