The following picture is the purification of the selected colony from the primary plate.

This was not a successful streak plate because there are no well-isolated colonies visible. The temperance for this is because I did not let the loop cool good deal sufficiently before streaking. attached I examined my isolated organism by phase melody microscopy. afterward examining the isolated unknown organism using the 40X objective with the phase contrast filter, I observed that the cells appear to be rod shaped and non-motile. After examining my soil sample chthonian phase microscopy, I performed gramme staining in order to determine whether my bacteria are of the class proteobacteria or firmicutes. I gram stained S. epidermidis and E. Coli as controls. The following photo is a gram stain of the S. epidermidis.
