In microbiology, colony-forming unit (CFU, cfu or Cfu) is a unit which estimates the number of microbial cells (bacteria, fungi, viruses etc.) in a sample that are viable, able to multiply via binary fission under the controlled conditions. Counting with colony-forming units requires culturing the microbes and counts only viable cells, in contrast with microscopic examination which counts all cells, living or dead. The visual appearance of a colony in a cell culture requires significant growt… WebThe formula of CFU/ml is: CFU/ml = (no. of colonies x dilution factor) / volume of culture plate. For example, 5 g of soil was placed into 10 ml water. The solution was serial diluted 10x (1/10 ...
