WebCFUs, or “colony forming units,” are a unit of measurement used to determine the number of live bacterial cells in a probiotic supplement or lab sample. In other words, along with other factors, a CFU count can give us some insight into the quality of a probiotic.*. Read on for a deep dive into colony forming units—what they are, what ... WebOne can then calculate backwards to estimate the number of cells in the colony. If one just wants an average number of cells per colony, one could pick up about 100 colonies, suspend them all together, count cells, and divide the final number by 100. This is faster than doing counts on 100 individual colonies, but of course one will only get ...
