    Determination of Concentration of Living Immobilized Yeast Cells by Fluorescence Spectroscopy

  • Original language description

    The aim of this work was to develop a method allowing measurements of concentrations of living immobilized cells using only intrinsic fluorescence of biogenic fluorophores in cells. Saccharomyces cerevisiae yeast cells were immobilized into alginate andinto a mix of alginate with prepolymerized tetramethoxysilane (TMOS) and measured in flow through cuvettes. Fluorescence intensity of intracellular NAD(P)H, its changes during aerobic-anaerobic transitions and the time delay between halt of medium circulation and rise of NAD(P)H fluorescence intensity correlated with concentration of living immobilized yeast cells. In case of alginate?TMOS layers, only relative change of NAD(P)H fluorescence intensity corresponded to the content of active biomass in thewhole range of measured concentrations.

    Stanovení koncentrace živých imobilizovaných kvasinek fluorescenční spektroskopii

  • Czech description

    Cílem práce bylo vyvinout metodu dovolující měření koncentraci žívých imobilizovaných buněk , která je založena na monitorování fluorescence biogenních fluoroforů v buňkách. Saccharomyces cerevisiae imobilizováné do alginátu a do směsi alginátu a přepolymerovaného tetramethoxysilanu byly monitorovány v průtočné kyvetě. Intenzita fluorescence intracelulárního NAD(P)H, jeho změny během přechodu z aerovaného do anaerovaného stavu a časová prodleva po zastavení cirkulace okysličeného media byly korelovány skoncentrací živých imobilizovaných buněk.
