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.

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.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.Title: Identification of Two Unknown Bacteria’s Through the Use of Gram Staining Introduction: The Gram staining of bacteria is a widely used method to identify unknown bacteria.The purpose of this method is to find out identities of unidentified bacteria.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).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.Seen in Figure 2.0 is a drawing of Escherichia coli showing a cluster of bacilli shaped bacteria represented at 21000X.This Escherichia coli as well as the Staphylococcus epidermis were both prepared slides that we looked at in our lab.
