โฆ Synopsis
Mixing times and gas hold-ups in a 250L bioreactor containing a phosphate buffer or an active fermentation were determined on-line using fluorometric (MEFS and NADH) probes as functions of agitation and aeration rates. Both mixing time and hold-up of a fermentaion can be determined using a MEFS probe. Hold-up may also be measured with a presently available commercial NADH probe.
