A 10-4 is performed on a culture of bacteria in orderto perform viable plate counts. From the dilution,*0.1 mL* ofsolution is plated on solid media, and 37 colony forming units growon the plate.

How many bacteria are in a single mL of the original culture?Express your answer to two decimal places using exponentialnotation. In exponential notation 540 would be written as5.E2. Please use an upper-case letter E.

  • Since only 0.1 mL is put on the plate, this counts as an extradilution!!!
  • Any time less than 1 mL is transferred, a dilution is beingperformed.
  • Any time more than 1 mL is transferred, a concentration isbeing performed.
