The Staphylococcus epidermis is cocci shaped and represented at 13000X.No tests were personally done to either the Escherichia coli or the Staphylococcus epidermis because they were both previously prepared in slides.For example, if you experienced a dog bite, a Gram stain test could be performed on your wound to determine what kind of bacteria it is and how the wound might proceed from the point it is currently at. Our findings from this lab should tell us the identity of the bacteria Unknown Y and Unknown G.

Gram positive bacteria have cell walls composed mostly of a substance unique to bacteria known as peptidoglycan, or murein. Gram negative bacteria have cell walls with only a thin layer of peptidoglycan and an outer membrane with a lipopolysaccharide component not found in Gram positive bacteria.

Gram negative bacteria stain red or pink after Gram staining.

The cell walls of Gram positive bacteria differ structurally from the cell walls of Gram negative bacteria.

The primary component of bacterial cell walls is peptidoglycan.

These molecules are crosslinked together by short peptides which help give peptidoglycan strength and structure.

Peptidoglycan provides protection for bacteria and defines their shape.This is a mixed culture of Gram negative Escherichia coli (red-orange) and Gram positive Staphylococcus aureus (blue-purple) stained using the Gram staining method.These categories are based on their cell wall composition and reaction to the Gram stain test.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.
