In the animation, notice the labeled microbial cell coming down the flow. When hit with the laser, it emits a fluorescence single because it is tagged with dye and also the scatter detector because it is larger then the minimum size. Both detectors have to be activated for the cell to be counted.
This slide gives an outline of the United States Pharmacopeia Chapter 61 which addresses microbial contamination in both raw materials and non-sterile finished products In the first line concerning Bacteria, notice that the incubation time is 48 to 72 hours Also, notice that the 1:10 dilution of the product means that if there is no counts, the results are recorded as <10 cfu/mL. In the Personal Care market, this is the situation well over 90% of the time. In the second line, the incubation time for yeast & mold is 5 to 7 days. The same reporting logic is followed.
This information looks even simpler to the technician on the software On this screen the results are shown for the first sample in the tray Both mold and bacteria failed (red color) and the yeast passed (green color)
