A stock of lytic bacteriophages produced 2000 plaques on a plate when 20 μl was plated with 0.3 ml of E. coli culture. How many plaques would you expect from a 1:1000 dilution of the same stock plated in the same way?
Homework Answers
For without dilution we are getting = 2000 plaques.
Now doing 1:1000 dilution = 2000 plaques X 1/1000 = 2 plaques.

a) During the exponential phase of bacterial growth, the lab strain of E. coli has doubling time of about 30 minutes. If you start with 10,000 cells per mL of culture, and let them grow exponentially 2 hours in a flask, what is the final density of the culture?

For the plaque assay, your T4 bacteriophage titer is 7.8x108 pfu/mL. You do six 1:10 dilutions of the virus, putting 10µL of each dilution in a tube of top agar with 100µL of E. coli. After pouring the contents of the top agar onto an LA plate, you incubate overnight. How many plaques would you expect to see on the final plate?

You want to dilute and plate an E. coli culture that has 3 *10 8 cells/ml. If you needed to dilute the above culture, starting from the undiluted stock, to a concentration of 500 cells/ml, how could you perform a serial dilution to achieve the desired final concentration?

Name One use of serial dilutions is to calculate the concentration of microorganisms. Since it would usually be challenging or even impossible to actually count the number of microorganisms in a sample, the sample is diluted and plated to get a reasonable number of colonies to count (usually between 25 to 250 colonies is the goal). Since each colony on an agar plate theoretically grew from a single microorganism,...

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...

Hello, just wanted to check my answers. Answer as many as you like/can. Thankyou. 1) Four grams of soil are added to 36 ml sterile water and mixed well. 0.1 ml of this mix was added to 9.9 ml sterile water. This was diluted by 4 successive 1/10 dilutions. 1.0 ml from the last dilution was used to prepare a pour plate. After incubation 289 colonies were counted. Calculate the # CFU/g soil. 2) A 0.1 ml aliquot of a...

Now it's your turn to construct a dilution scheme to achieve a countable plate. You start with a stock culture of 5.4 x 10^8 cells/mL. Draw a dilution scheme that will produce a countable plate (<300 colonies). Show how much is transferred at each step, how much media is in each flask or tube, and how much you will plate. Show how many colonies you expect on your final plate. Once you have constructed your scheme, answer this question: Is...
