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...

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? Applications A research laboratory in pharmaceutical company is studying environmental factors that would inhibit the growth of Archaea. One question they have is if adding of antibiotic penicillin would be...

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...

LAB EXERCISE #6: Kirby-Bauer Disk Diffusion Test for Antibiotie Sensitivity Determination The Kirby Bauer Test is an agar diffusion test that is used to determine the effectiveness of antibiotics killing various species of bacteria. Filter paper disks saturated with the antibiotic of interest are placed a Mueller-Hinton agar plate on which bacteria that has been isolated from a clinical sample has been sarcad. The antibiotic then diffuses from the disk...
