Identification of A Mixed Culture Unknown
An experiment such as this one serves the purpose of allowing us, the students, to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the results. I obtained tube number twelve to run various tests on. There are only two microorganisms, one is Gram positive and one is Gram negative, inside the test tube. The Gram positive possibilities are to be narrowed down from Bacillus cereus, Clostridium perfringens, Corynebacterium xerosis, Enterococcus faecalis, Streptococcus agalactaie, Staphylococcus aureus, and Staphylococcus epidermidis.
