Microbiology. How would you obtain a pure culture of a single bacterial species from agar plate holding a mixed population of bacteria? What methods would you use to identify this bacterium that you have isolated?
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...

and Lab Exer n this experiment you will evaluate effect of UV light on bacterial growth. UV light affects growth by interfering with DNA, resulting in thymine dimer formation. The dimerization is confined within adjacent thymine residues on same strand (intrastrand ). These dimmer lesions have consequence on DNA functions including interference in DNA replication, transcription etc, so UV exposure of cells can lead to lethal effects for bacterial multiplications. This forms the basis for UV method to control bacterial...

Now knowing the MPN value, you decide to do a dilution series in order to figure out the original bacterial concentration of the Swimming Hole, just in case it is not a coliform causing the gastric distress and simply a bacterial overgrowth. You perform the following dilution set: from your 16.3-liter Swimming Hole sample you transfer 10.7 x 10-3 liters into container A which has a volume of 6,250ul, you then transfer 1.7 mL from container A into container B...

You are working in a laboratory producing new antibiotics for human and veterinary use. One compound with potential value inhibits the action of prokaryotic ribosomes. The compound, however, was shown to inhibit the growth of animal cells in culture. What is one possible explanation for its effect on animal cells?
