Exact number can be used for colony count instead of CFU !
Set plates and start a test !
Figure a. shows the condition when colonies were detected by MicroBio µ3D at 8h. The colonies pointed out by white arrow on the agar plate are hardly visible to the eye. But the 3D shadow images of two colonies are clearly recognizable by MicroBio µ3D and recorded as two colonies..
Figure d. shows the condition when incubation of the agar plate proceeded to 24h. At this timing, two colonies overlapped together, forming single large colony that is pointed out by white arrow. If the plate were visually inspected after 24h incubation, colony count would be treated as 1cfu. However, two is the correct count as the chronological 3D shadow graphs show.
