OpenCFU - Count your colonies
Counting colonies on agar plates is a widely used method in microbiology. OpenCFU is a free software that should facilitate (and render more reproducible) the enumeration of colony forming unit (CFU). You can simply run the program on your computer and input pictures of plated bacterial colonies (or other cells).
5.1: Introduction to Enumeration of Bacteria - Biology LibreTexts
In a microbiology lab, we frequently determine the total viable count in a bacterial culture. The most common method of measuring viable bacterial cell numbers is the standard or viable plate count or colony count. This is a viable count, NOT a total cell count. It reveals information related only to viable or live bacteria.
How to Count Colonies in Microbiology - Sciencing
2018年3月10日 · The primary trick in counting colonies is to count each colony dot once. One approach is to set the Petri dish on a grid background and count the colonies in each grid cell, moving in a methodical pattern through all of the cells. Marking counted colonies on the back of the Petri dish can also be a helpful approach.
1.15: Determination of Bacterial Numbers - Biology LibreTexts
The number of colonies we count on a petri plate enables us to calculate the CFU or colony forming units. CFU is a measure of the concentration of the live, viable bacterial cells capable of reproducing when grown on a petri plate in cells per milliliter (cells/mL).
8: Bacterial Colony Morphology - Biology LibreTexts
This exercise will help you identify the cultural characteristics of a bacterium on an agar plate - called colony morphology. Although one might not necessarily see the importance of colonial morphology at first, it really can be important when identifying the bacterium.
Bacteria Colony Counting Based on Machine Learning Algorithms
The traditional and preferred method for quantifying microbe populations is by colony enumeration. This process involves serially diluting liquefied samples, plating the samples on media plates, and counting the resulting colony-forming units.

2022年9月11日 · A colony counter is a device that is frequently used to count bacterial or other microorganism colonies on a plate that contains a gelled growth medium. Microbiologists have to tackle the daunting task of counting colonies, which can occasionally be undersized and obscured by the unique color of the culture media or the enumeration process itself.
