Bacterial fermentations

The ABER Biomass Monitor is ideal for monitoring and controlling high-density E. Coli fermentations

Recent data from the University of Hamburg demonstrates how the live cell concentration in a high density bacterial fermentation can be effectively monitored using the Biomass Monitor 200. Subsequent work compared the differing readings utilising both an Optical Density monitor and ABER Instruments Biomass Monitor. At the point when fermentation has become nutrient limiting (and the growth rate has changed) the Optical Density reading rapidly increases as the cell debris and necromass accumulates. However, the ABER Instruments Biomass Monitor continues reading accurately, providing a true reflection of the live cell mass.
