Is this the same as asking how many CFUsmL I know how to do

Is this the same as asking how many CFUs/mL???? I know how to do the calculation for CFU/mL...

Seventy-three colonies grew in nutrient agar from 0.1 mL (milliliters) of sample withdrawn from a solution diluted to 10^3 in a standard plate count procedure. How many cells/mL were in the original sample? 730 7, 300 73,000 730,000

Solution

CFU/ml = number of colonies * dilution factor / volume of culture plate

according to above question

the plate of the 10^3 dilution yield , a total count of 73 colonies.

then the number of bacterial gowth in 1 ml of the sample (origional) can be given as

CFU/ml = 73 * 10^3 / 0.1

here you will get value of cfu/ml

now you have to convert CFU/ml to log value

you can do log(CFU/ml)

hope this will work in finding your answer.
