pH sensitive fluorescence probes
Marková, Kateřina ; Obruča, Stanislav (referee) ; Mravec, Filip (advisor)
The goal of this thesis was to suggest the suitable method for measuring bacterial cytosolic pH in bacteria strain Cupriavidus necator. Fluorescent microscopy was chosen to obtain scan of bacteria and time-resolved fluorescence was chosen to obtain a calibration curve. BCECF-AM was used as a pH-sensitive fluorescent probe. It was suggested that the external calibration is more suitable than internal one for the prokaryotic type of cells. Bacteria H16 shows a long fluorescence lifetime only on the granules containing PHB, while in PHB-4 the longest fluorescence lifetime occurs randomly throughout the cell.
