Web1 Aug 2024 · The number of colonies we count on a plate gives us the CFU or colony forming units, when we divide the CFU, by the volume we plated we get CFU/volume à CFU/mL. For example, if we counted 32 bacteria on a plate that had received 200 μl of a 10-6 dilution, we would do the following math: (Lab 9.1) 32 C F U s 0.2 m L = 160 C F U m L. r50 insulation value
