Abstract

A method and apparatus for cell volume and biomass estimation by sampling a fermentation broth and analyzing an image of the broth using brightness thresholds to distinguish between background, cellular regions and cytoplasmic and degenerated regions and summing corresponding areas in the image. Volumes can be calculated from the areas by treating the organisms as geometrical bodies and biomass derived by multiplying the volume by a density.
