Every winter the snow falls, and people get sick. Both of these items have components in common. Both the snow that falls, and the bacteria that gets people sick may be small, but when allowed to accumulate, characteristics of them become visible. While snow is made from frozen water, with flakes differentiating in the structure of them, bacteria is like that, to a sense. Certain bacteria families may have similar genomes, they do have slight differences that make up what they are. Just like snow being made of frozen water, bacteria is made up of the same four genomes. They’re just in a different order, which makes them unique
One way to tell the difference is to see if the bacteria is gram positive or gram negative. Gram-Positive bacteria contains peptidoglycan (which is a polymer of amino acids and sugars), while Gram-Negative Bacteria does not have as much. (Holbrook, 24)
Because Gram-Positive contain peptidoglycan, they do not form string in the KOH test. The opposite is true for Gram-Negative- it will form a string due to its chemical makeup. The Gram-Positive bacteria uses the peptidoglycan to act as a wall, so the KOH will not react with it. However, the cell membrane on the Gram-Negative bacteria reacts with the KOH, which creates a slight polar charge on the bacteria, which causes it to form a string. If too much force was added by pulling on the toothpick, this causes the string to break. Therefore, when applying the KOH string test, one must be
