IDENTIFYING AN UNKNOWN CULTURE (7 pts) Hypothetically: You are unknown identity-Escherichia coli, Micrococcus luteus, o given an unknown bacterial broth with the following three options as your r Pseudomonas aeruginosa. you know that your hypothetical E.coli strain is motile while the other two . luteus organisms are not. You also find that the Ecoli is lactose positive.and mannitol negative while M is lactose negative and mannitol positive, and P. aeruginosa is negative for both sugars. E.coli and P. aeruginoso are facultative anaerobes while M. luteus is aerobic. And finally, from previous knowledge (aka your notes), you know the Gram stain, cell and culture morphology of the three organisms. Aftertesting your unknown growth of circular colonies on NA with no visible pigmentation, Gram negative bacilli, motility was indistinguishable because the needle was slanted when you inoculated, lactose and mannitol negative, and facultatively aerobic growth in an FTM tube culture using category I-IV tests, you find the following results-you had ous 1.) What bacterial culture did your lab instructor give you? (2 pts (There is only ONE correct answer for this and it is one of the three listed above) 2.) Give three reasons justifying your above answer. (3 pts) (Understand that justification of your unknown identity is an important part of your final paper, so give three reasonable answers that leave no room for counterarguments) 3.) Give one good reason why there may have been no colony pigmentation. (1 pt) 4.) Name one thing you would repeat or do over again given limited time and resources and WHY you would want to do this.
