- 1mL Stock #1 1mL 9mL #2 9mL #3 1mL A 9mL #4 0.1mL 1mL O O B 9mL #5 1mL 1mL 9mL #6 O Using the picture serial dilution scheme and the following information (plate A has 276 colonies, plate B has 298, plate C has 2, and plate D has 30), calculate the average number of colony forming units per mL in the stock tube. Make sure to only use countable plates. Round your answer to the nearest one. Write only the number with any needed commas or decimals. Do not include units. 0.1mL 1mk D OPlease note that these counts have all been done with Trypan Blue. Therefore, all cultures have been diluted two-fold (equal volume of cell suspension + equal volume of Trypan Blue). Take this into account when determining cell number. Any dilution listed in table is an additional dilution. Live and dead cells listed below represent the total number of cells in 5 large counting squares. *1 x 105 cells/ml cells were seeded into each well of the 24 well plate(s) on day 0 to begin the growth study. Plot this value at the zero time point on your graph.1These numbers represent the total number of cells counted in 5 large squares from three separate counts.You need to prepare medium for your culture cells. Your salt solution is supplied at a 10X concentration but needs to be 2X for use. You also need to add fetal bovine serum for a final concentration of 8%. What would you add of each for the correct final concentrations in 5 L of media?

How many cfu/ml are in the milk if 200 colonies were counted?Ten grams of hamburger were added to 90 mL of sterile buffer. This was mixed well in a blender. One-tenth of amL of this slurry was added to 9.9 mL of sterile buffer. After thorough mixing, this suspension was further dilutedby successive 1/100 and 1/10 dilutions. One-tenth of a mL of this final solution was plated onto Plate Count agar.After incubation 145 colonies were present. How many colony-forming units were present in the total 10 gramsample of hamburger?
- Design a serial dilution of a 25-gram cheese sample to achieve a final dilution of 10-5 using 90 ml blanks. Show how you would plate out 10-2 through to 10-6Five grams of soil were added to 45 ml of sterile water and shaken vigorously. After that, 0.1 ml of this was added to 9.9 ml of sterile water. This was further diluted by four successive 1/10 dilutions. The last dilution was used to prepare a spread plate. After incubation, 58 colonies were present on this plate. What is the CFU/g of the soil sample? Assume: 1 g = 1 mLA urine sample is diluted 1:1,000. If 0.1 ml were put into a Petri dish with melted agar, how many CFU/ml are in the urine if 158 colonies grow?

Describe the appearance of the protein solutions in each of the tubes after addition of the alkaloidal reagents.Three grams of soil from the ground were added to 27 mL of sterile water and shaken vigorously. After the soil particles settled, 0.1 mL of this was added to 9.9 mL of sterile water. This was further diluted by 4 successive 1/10 dilutions. One mL from the last dilution was used to prepare a pour plate. After incubation, 289 colonies were present on this plate. What was the number of colony-forming units/gram of the soil?Below is a diagram of the serial dilution of a culture with 1 x 10º cells.
