Luckily, my results still supported my hypothesis, which meant that as I flipped the petri dish over, all four of the Erythromycin disks spontaneously landed onto the correct sectors. A sample was taken from the isolated nutrient agar and a gram stain was done as directed by the lab manual 1.
This final lab report will encompass labs 9 through Secondly, the culture was very difficult to isolate because it grew extremely slowly on the EMB plates and a pure culture took two weeks to achieve. After a successful Gram stain it was classified as a Gram positive cocci which narrowed it down to three bacteria; Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecalis.
Microorganisms are very small organisms that require the use of a micro scope to visualize them, which are bacterium, viruses, fungi the most common and others which are not so common such as parasites.
There were five labs that were conducted in this lab report. The plates were incubated at 37C for 48 hours, and Gram stain procedure with observation under light microscope was performed.
A safranin was drop to the mixture to cover the colorless area and then washed again with distilled water. Contrary to this, studies have found that B.
Scientific writing is written differently from other types of writing. Upon return and observation, the MSA did not yield a good isolated colony. A negative VP test and a positive sorbitol test concurred with the expected results of P.
