The specific communities of bacteria allowed us to perform a Gram stain for both substances.

Although this Gram staining process is very important to the scientific world, it also has a major impact on our everyday life. Goldstein, 1980) The stain would make it very easy for the doctor to look under a microscope to determine what bacteria it is and also the shape and size of the bacteria may help to conclude what might be present.

It had a defined bacilli shape and ended up red after the Gram staining.

This bacteria was twice as large as bacteria G, and its KOH result was a gooey suspension.

The Gram staining method, developed by Hans Christian Gram, identifies bacteria based upon the reaction of their cell walls to certain dyes and chemicals.

The differences between Gram positive vs Gram negative bacteria are primarily related to their cell wall composition.Peptidoglycan is a macromolecule composed of sugars and amino acids that are assembled structurally like woven material.The amino sugar component consists of alternating molecules of N-acetylglucosamine (NAG) and N-acetylmuramic acid (NAM).Considering how the Gram stain color was red and the KOH result was a gooey suspension, the identification of the bacteria seems to be Gram-negative.This bacteria ends up Gram-negative and red because it does not maintain the violet dye it comes into contact with during the Gram staining process.Discussion: I believe that the Unknown bacteria Y is Gram-negative.I have come to this conclusion from the results of the tests I performed.Both bacteria Y and G’s full results can be seen in Table 2.1.It shows a visual representation of how these bacteria compare in the various tests they went through.By means of aseptic technique, use bacteria from colonies formed in your petri dish and mix bacteria with distilled water on a new slide. In Biology 107: Introduction to Cell Biology Laboratory Manual 2011/2012. Results: The first Gram stain I observed was Figure 1.0, the Unknown G bacteria under 1000X magnification.Allow slide to dry and advance to performing a Gram stain procedure. Faculty of Arts and Science, Grant Mac Ewan University, Alberta, Canada. The result of the gram stain color was purple, and it had a definite cocci shape.
