No. of Colonies of Bacteria Solution

STEP 0: Pre-Calculation Summary

Formula Used

No. of Colonies = (Colony Forming Unit per ml*Volume of Culture Plate)/Dilution Factor
n_c = (CFU*v_c)/DF
This formula uses 4 Variables

Variables Used

No. of Colonies - No. of Colonies is a group of bacteria, fungi, and other microorganisms grown on a solid agar medium.
Colony Forming Unit per ml - (Measured in Cells per Cubic meter) - Colony Forming Unit per ml is a measure of viable bacterial or fungal cells. In direct microscopic counts (cell counting using haemocytometer) where all cells, dead and living, are counted.
Volume of Culture Plate - (Measured in Cubic Meter) - Volume of Culture Plate is the the amount of a substance occupying a particular volume of culture plate.
Dilution Factor - Dilution Factor is the factor by which the stock solution is diluted.

STEP 1: Convert Input(s) to Base Unit

Colony Forming Unit per ml: 14 Cells per Liter --> 14000 Cells per Cubic meter (Check conversion here)
Volume of Culture Plate: 10 Cubic Meter --> 10 Cubic Meter No Conversion Required
Dilution Factor: 7 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

n_c = (CFU*v_c)/DF --> (14000*10)/7

Evaluating ... ...

n_c = 20000

STEP 3: Convert Result to Output's Unit

20000 --> No Conversion Required

FINAL ANSWER

20000 <-- No. of Colonies

(Calculation completed in 00.004 seconds)

What is CFU?

A colony forming unit, or CFU, is a unit commonly used to estimate the concentration of microorganisms in a test sample. The number of visible colonies (CFU) present on an agar plate can be multiplied by the dilution factor to provide a CFU/ml result.

How to Calculate No. of Colonies of Bacteria?

No. of Colonies of Bacteria calculator uses No. of Colonies = (Colony Forming Unit per ml*Volume of Culture Plate)/Dilution Factor to calculate the No. of Colonies, The No. of Colonies of Bacteria formula is defined as the amount of colonies of bacteria formed in the culture. No. of Colonies is denoted by n_c symbol.

How to calculate No. of Colonies of Bacteria using this online calculator? To use this online calculator for No. of Colonies of Bacteria, enter Colony Forming Unit per ml (CFU), Volume of Culture Plate (v_c) & Dilution Factor (DF) and hit the calculate button.
