The Cerex MAX sensor is an optical density type sensor appropriate for use in the monitoring and control of a number of fermentations (ref. 2, 4, 6,7). It has been successfully used in high cell density commercial bakers’ yeast fermentations over extended numbers of fed batch cycles (ref. 1). The MAX sensor has also been used in research applications for the monitoring of high temperature bacterial fermentations at lower optical densities (ref. 3) as well as for E. coli fermentations (ref. 5,8,9).
