In microbiology, a 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 ...
They are used in many dietary probiotic supplements. Theralac contains the strains Bifidobacterium lactis BI-07 and Bifidobacterium lactis BL-34 [ 5 ] (also called BI-04) in its probiotic capsule. Bifidobacterium animalis lactis HN019 (DR10) is a strain from Fonterra licensed to DuPont, which markets it as HOWARU Bifido.
The colony-forming unit (CFU) is an appropriate description of the colony's origin. In plate counts, colonies are counted, but the count is usually recorded in CFU. Due to the fact that colonies growing on plates may begin as either a single cell or a cluster of cells, CFU allows for a correct description of the cell density.
Probiotic supplements typically contain between one and ten billion colony-forming units (CFUs) per dose. [42] A higher number of CFUs does not provide additional probiotic effects, but may have unintended consequences of causing digestive discomfort, such as bloating, gas, and diarrhea. [42] [43]
Total viable count (TVC), gives a quantitative estimate of the concentration of microorganisms such as bacteria, yeast or mould spores in a sample.The count represents the number of colony forming units (cfu) per g (or per ml) of the sample.
The bioburden quantification is expressed in colony forming unit (CFU). There are generally established guidelines for the maximum CFU that a drug product can contain. [4] Contact plates or sterile swabs can also be used to test for microbes on a surface when compounding sterile products to ensure compliance with USP 797. [5]
