Identification of Unknown Bacteria Number 63 The best and most accurate way of identifying an unknown microorganism is by sequencing its DNA, but this is very expensive and only used in highly qualified labs. So, the identification of unknown bacteria number 63 was be done by putting the bacteria through numerous laboratory tests. Microorganisms are different among each other by their macroscopic morphology, microscopic morphology, and the unique metabolic processes they use to survive and reproduce. Identifying an unknown microorganism in the laboratory is important because knowledge is gained on the appropriate way to cultivate an organism, how to correctly read the result of a test, and learning about the different characteristics of the bacteria. All of the following tests were done using the best sterile technique and the most new turbid bacterial growth subculture. The detection of unknown bacteria number 63 began with examining macroscopic and microscopic morphology. Macroscopic morphology of unknown bacteria was done by a streak for isolation of bacteria on a plate with nutrient agar, which allowed the bacteria to ingest the nutrients it needed to survive and reproduce to form pure colonies. After growth, the colonies appeared to be mucoid, beige in color with smooth edges and no elevation. Another macroscopic test was done in a tube with semi-solid agar to test for motility and the result of this test…
