This paper presents a method to determine the cake specific resistances( CSR) for con-stant pressure filtrating fermented broth of Bacillus amyloliquefaciens Q–426 using MATLAB’ s Curve Fitting Toolbox. The acquired data was imported and smoothed via the graphical user in-terface ( GUI) . Smoothing spline was used to produce smooth curves to fit to the data, and the CSR was calculated by numerical differentiation. The study showed that the calculated results are accurate and reliable. Compared with the traditional calculations, this method provides visu-alized results, and the GUI simplifies the calculation and makes it intuitive. It can be easily mastered for those who are not adept programmers.
