On-line FT-Raman spectra recorded at the start (0 h) and end (120 h) of bioprocesses: a fermentation of glucose by Rhodotorula, and b fermentation of glycerol by Schizochytrium (the presented spectra are averages of three consecutive spectra, and were normalised to glass-related peak at 800 cm−1; the spectrum of the empty glass flow cell is added for reference). HTS-FTIR (c and d) and HTS-FT-Raman spectra (e and f) of freeze-dried microbial biomass after 8 h and 120 h of bioprocess: (c and e) fermentation of glucose by Rhodotorula, and (d and f) fermentation of glycerol by Schizochytrium (spectra were baseline corrected and normalised for better viewing)
