All organisms possess special traits and characteristics that enable the microbial to differentiate from other types of organisms, when placed in a certain environment. The purpose of this lab was to be able to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructors. The techniques used to identify the two unknowns were done so by applying all of the methods that were learned thus far in microbiology laboratory class. Each test that was conducted provided us with some key information about the unknown microbes in question and how the bacteria function. All the laboratory students possessed an unknown microbe that was a gram negative rod, which narrows down that category of microbes to being Escherichia coli, Samonella enteric or Enterobacter aerogenes . The other unknown microbe had to be either a gram positive cocci ( Enterococcus faecalis or Staphylococcus aureus ) or rod ( Bacilis subtilis or Corybebacterium glutamicum ). The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways, each was used in a way to help recognize those specifics and identify the
