E.coli Bacteria present in one CFU at 9:00 pm = 1.07 X 109 bacteria and E.coli at 11:00 am = 1 generation time. That means 2.66X 10^ 9 cells per 1 CFU.
The average CFU in probiotics is between 1 and 10 billion CFUs per serving. To find out the number of CFU in the sample then the number of colony forming units on thee countable plate is multiples by 1/FDF. For example when the countable place has 200 colonies then 200 CFU and the FDF was 1/4000.
CFU measures the viable cells.High number of E.coli bacteria in water indicates that contaminated by feces. and it increasing the risk of exposure to pathogens that causes illness.
