    Background Background continued... Questions Experiment 2: TSI The triple sugar iron agar (TSI) can identify gram negative bacteria based on how they metabolize carbohydrates. It contains three carbohydrates-glucose, lactose and sucrose, in addition to sodium thiosulfate which some bacteria use in the production of hydrogen sulfide (H2S). It also contains iron in the ferrous form and phenol red as a pH indicator. TSI is poured into a tube when heated to a liquid form, and the tube is slanted as...

    in the Micro lab, I got an unknown microorganism. The assignment is to find the microorganism by performing various tests on it. My hypothesis is: Unknown organism is virulent and can cause diseases in the human organism. My question: Which 4 test should I do first to detect my organism and why those tests in particular? (I am thinking aerotolerance, endospore, hemolysis...) depending on each test result can you give an example of the microorganism that it can be? Colony...

  • You are given a mixed culture of two organisms in a small tube of TSB.

    You are given a mixed culture of two organisms in a small tube of TSB. These two organisms include a Gram-negative strain (your bacterial strain to identify) and a Gram-positive strain (a contaminant). Your first task is to isolate these organisms which will help you identify which Gram-negative strain you are working with. 1) You inoculate two streak plates on TSA media and MacConkey Agar using aseptic technique. For each medium, state whether the medium is selective, differential, or neither and...
