In regards to bacterial growth define colony?
Each colony is a mass of bacterial clones, usually founded by one individual cell. So each colony represents one original microbe.
What advantage does the streak plate method have over the pour plate method?
A disadvantage of the streak plate technique could be colony isolation problems. If the streaking technique is not done properly or if there is too much of an organism present on the inoculating loop then the cells can cluster and form what looks like one colony but it can actually be a couple colonies (made from a couple cells). This can cause an inaccurate colony forming unit count.
What is the difference between a tissue and a colony?
A bacterial cell is a unit of bacterial colony. In colony of bacteria there can be thousands to million of cells can be present. The morphology of the colony of bacteria can be seen with naked eyes without the help of any gear. Where as the bacterial cell can only be seen under microscope.
What does the cell theory tell us about cells?
Cell theory states: -All living things are made up of cells. -Cells are the basic unit of structure and function in all living things. -Cells arise from pre-existing cells.
What is the smallest unit of life?
A cell is the smallest unit of life
How do you compute colony forming unit per plate?
1.Direct Microscopic Counts (DMC) for both viable and nonviable cells
What does the initials CFU stand for?
It means a lot of things. Colony Forming Unit, CFU is also the Kerkyra, Greece airport code, Commercial Farmers Union, Coliform Forming Units, and Contract Follow Up.
What is mean by cfu?
It is the concentration of bacteria in any solution.CFU stands for Colony Forming Units. Colony forming unit is a form of measuring bacteria grown on a streak plate.
What are the Stages of RBC formation?
Stem Cell-Burst forming unit-Colony Forming Unit:erythropoeitin-progenitor cell-reticulocyte-erythrocyte
What is 1000 cfu in water colony testing?
1000 colony forming unit/ml in water...500 cfu/ml is considered standard for acceptable drinking water

What unit of measurement is used for bacterial colonies?
Many aspects of bacterial colonies may be measured for example colony size or appearance can be useful. The measurement which is perhaps the most useful however, is the colony forming units per ml (or cfu) which indicates how many bacterial cells are present to form colonies on the medium. This is a relatively simple calculation which is done by initially counting the number of colonies present on the medium. this number is then multiplied by the inverse of the dilution used. For example, if the dilution of the bacterial broth was 10-2 and the number of colonies on the medium was 60, then the calculation would be 60 x 102. This result is then divided by the volume of sample used in ml and will give you the number of colony forming units per ml present on the medium. Ben McD

Does a colony count really give a total count of microorganisms per unit sample of the original material?
Yes, each colony that forms on the plate was the result of a single microorganism. If you can know the quantity of the unit sample, you can know the number of microorganisms that were in that sample by counting the colonies.
