First, i did serial dilution and plated them. e.g., for e.coli, I found that the plates came as TNTC from 10-1 to 10-5 , but 10-6 . 10-7 and 10-8 came as 628, 211 and 98 respectively. i chose 10-7(211), so it comes to 2.11 x 10^9 cfu/ml. from here, how do i dilute the suspension to get 1 X 10^6 cfu/ml? Plz answer.
