microbial sensivity lab: Why does the Kirby-Bauer procedure require that the concentration of the bacteria be the same, the stage of growth constant, the growth medium the same, and the concentration or amount of drug in each disk constant?

Please answer fast Dilution Problem. A culture of Staphylococcus is diluted as follows: (1) 20mL are added to 80mL of water. (2) 10uL from (1) are then added to 9.99mL of water. (3) A 10-2 dilution is made from tube # (2). (4) 100uL from (3) are plated for a pour plate and incubated.   Growth Problem.A culture with approximately 2x103 cells/mL were incubated. After 3 hours, the number of cells had increased to 3x105. a) How long was the generation time in minutes?b) How many generations have occurred

Microbiology lab report (50 points) - There are many local plants and herbal products that claim to have antibiotic or antimicrobial activity. For this report I would like you to research and select a local plant or herbal product that is reported to be antibacterial. Then I want you to design an experiment using the Kirby Bauer method to assess the antibacterial properties of the plant or herb you have selected. Your lab report will require an introduction (describe the plant you have selected and it's reported properties, explain the Kirby Bauer methods for testing unknown plant extracts, include your materials and methods, your predicted results, any conclusions you can draw and your list of references. This assignment requires some research on your part. Select a local plant, or an herbal supplement or something from the grocery store that has reported antibiotic properties. In your introduction, describe the plant you selected and why, how it is used and any interesting history of…
