Question 6
Lab 16 Report 5. You are provided with a yeast culture that is very turbid. You are asked to make 10-fold dilutions of the culture. You are given tap water, test tubes that hold maximum volume of 10 ml, and a 1 ml pipette for your work. How would you make this dilution? Fill in the blanks (Red and Blue) on the figure to answer this question. 1ml 1ml 1ml 1ml 1:10 1:100 1:1000 1:10000 my mi water...

Please show how to do these enumeration questions by showing the work. What is the dilution factor if you add 625 µL of culture to 4.375 mL of dilution medium? You count the 10-3 dilution of a yeast suspension using the 1/25 mm2 boxes : you find 45 cells in box 1, 15 cells in box 2, 42 cells in box 3, 23 cells in box 4, and 26 cells in box 5. a) What is the original concentration of...

1. You have a bacterial cell culture with a concentration of 1x109 cells/ml. You need to dilute the cells to a concentration of 1x103. What is the correct ratio for this dilution? 2. You add 0.1 ml of a yeast culture to a test tube that contains 9.9 ml of buffer solution. What is the dilution factor of this mixture? 3. In a 1000 µl total dilution volume, the volume of cell culture used is 800 µl. What is the...

Hi
I am im a biochemistry lab and we are doing an experiment titled:
PCR Amplification of LeuRS F C Terminal Domain. I am having
troubles figuring out the rest of my caluclations.
I already did the calculations for the first dilution set, I
was wondering how I would do the calculation for the second
dilution set.
Also I was wondering how I would determine the theoretical
values for my data. Is there a specific formula I can use?
If...

Suppose you would like to determine the number of bacteria in a culture via an aerobic plate count. Explain (with pictures) how you would set up a dilution series (104, 106, 10) using the fewest number of dilution blanks. Draw and label your tubes and plates with each dilution. Show all volumes including transfers, amounts in tubes, and amounts plated 1. You want to set up a 1:10 dilution series, so that you can plate a 10-1, 102, and a...

VPC 2. You have received a sample from a sewage treatment plant, and have been asked to determine how many CFU/ml are in this sample. You want to make a 1/100,000 fold dilution, but the smallest volume you can measure is 1.0 ml, and the tubes available to you only hold 10 ml. Draw a scheme showing how you would do this.

phenol is in each of your unknowns. 1. You will be given a nitrophenol solution of concentration 400 nmoles/mL and you will use this stock solution to make a serial dilution as follows: To make the serial dilution you need to prepare 5 tubes with 1 ml water. Next, add 1ml from the 400 nmoles/ml stock to the first tube. Pipette the solution up and down carefully and remove 1 ml of this solution to the next tube. Repeat this...
