Five Things to Remember When Comparing Microbial Growth Rate Programs
High-throughput measurements of microbial growth rates have been made possible by using microtiter plate readers to measure the growth of cultures in the wells of microtiter plates. It is not necessary to use a very sophisticated or expensive plate reader… Read More ›

Don’t Make This Common Mistake When Calculating Growth Rates
Failing to understand the difference between linear and exponential time can undermine your research. by Dr. Barry Hall Over the last decade high-throughput measurements of bacterial growth rates by using microtiter plate readers has become increasingly common. Indeed, some plate… Read More ›

Reliable, Reproducible Overnight Cultures
Dr. Barry Hall Many microbiology methods begin with an overnight culture, but few discuss how to prepare a reliable overnight culture. Typically, an overnight culture is started by inoculating a single colony into rich broth medium and shaking the culture… Read More ›

BRI Launches New Software Program CGR2 for Comparing Growth Rates
We’ve just released a new companion tool for the GrowthRates program called CGR2 (Compare GrowthRates), available today for licensing.
CGR2 is a statistical program specifically designed to assess the results of a growth rate experiment that has been analyzed using the GrowthRates program.

The Origins of the GrowthRates Program
Learn about the origins of the GrowthRates program, including the resulting published paper, which has been cited more than 300 times.
At a Society for Molecular Biology and Evolution meeting in 2012, Dr. Hall met a graduate student named Hande Acar and spent some time discussing her work in the lab at the Institute of Science & Technology Austria. She described the wonderful new microplate reader they were using to monitor the growth of bacterial cultures. The reader could automatically follow the growth of 96 cultures for hours, or overnight, and report the density of each culture at specified reading intervals.
The problem that Hande encountered was that it took days to do the calculations that would turn the resulting raw data into useful growth rates.
