Calculate bacterial growth parameters from optical density (OD) measurements over time, including the exponential growth rate and doubling time. Use this tool when monitoring a liquid culture to determine the optimal harvest time, compare growth phenotypes between wild-type and mutant strains, or standardize inocula for reproducible experiments. The tool fits the exponential phase of your growth curve — a short doubling time indicates healthy actively dividing cells, while deviation from exponential growth signals entry into stationary phase.
