Technical Abstract: Determination of enzyme kinetics, microbial growth rates, substrate utilization rates, and product accumulation rates requires derivatives to be calculated with a method that can be duplicated and yield consistent results. Here I discuss two methods that have been suggested in the literature and provide spreadsheet formulas for the needed equations. A cubic spline method proved more versatile in its use even though the spreadsheet programming was elaborate. The methods discussed were tested with published literature data for cell growth and a preferred technique was developed based on smoothing the data and using this smooth data for rate calculations.
