  • Serial dilution problem

    (Therefore, if we plated 1 mL of Sample B, we would expect to find about 1100 colonies in a 1 mL sample.) Yet, Sample B was the result of a 1:10 dilution of Sample A. Therefore, Sample A has 11,000 bacteria/mL. But, we can go further if we want.

  • Using a Serial Dilution to Count Bacteria in a Sample

    Question b) asks if there would be a change if the first dilution was made by adding 1 ml of sample (lake water) to 9 ml of diluent. 1 ml into 9 ml would give a dilution of 1/10.

  • Transformation and competent cells

    1.If you spread 0.1 ml of 10^-3 of a sewage sample on a plate, and obtained 221 colonies on the plate after incubation, how many CFU/ml were present in the undiluted sewage sample?

  • a classic "dilution series" problem

    After this, you are asked to prepare another tube by putting 1 mL of the first dilution (10-2) into a tube with 9 mL. This second dilution would be a further 1/10 (or 10-1) dilution, for a final 1/1000 (10-3) dilution of the original culture.

  • Dilution of Bacterial Cultures

    3949 Diluting bacterial cultures. You have a bacterial culture with a concentration of 3.4 x 10^9 cells/ml. If you dilute the culture 10^-8, what would be the final concentration?

  • Control of Growth and Viability

    Viable colony will form and the original number of viable bacteria in the sample can be calculated from the number of colonies formed multiply by the sample dilution. (4) For example, supposed you use 1.0 ml of a 1 X 10^6 dilution give you 150 colonies

  • Estimating microbial growth

    You can make further dilution from dilution 3 like, 10 ul (dilution 3) and 90 ul water to yield dilution 4 ( 10 X 10 X10 X10). If you stop here, then you will have a 1 X 10e4 dilution.
