In situ fluorescence measurements—clarifying or blurring the picture?

Abstract

Several studies on fermentation systems have been made with in situ fluorescence probes during the past fifteen years. These probes normally contain a stable UV light source and filters for selection of the appropriate excitation and emission wavelengths. The objective of different studies has varied. Culture fluorescence has been used for on-line biomass estimation, for monitoring of metabolic changes and for process control purposes. In this short review, different applications of in situ fluorescence measurements are discussed. © 1993 IUPAC
