The fermentations were carried out at Vito utilizing the experience of VTT. The fermentations were monitored by both Timegate and Kaiser Raman spectrometers. The substrates used were xylose and xylitol and the product xylitol. Dissolved oxygen, off-gas analysis were also carried out. Offline samples were taken for further analysis. Further pure-component and mixture samples of the used components in the expected concentration ranges were prepared and measured by both devices and serve as calibration ...

Measurements using Ramen spectroscopy can be perturbed by ‘background’ fluorescence during fermentation originating from the organism, the feedstock, and/or the medium. Data from the ‘Ethanol Production’ use case involving an industrial strain of the yeast S. cerevisiae (RWTH) will investigate the various sources of fluorescence and their effects on fluorescence at the end of fermentation. New and collated datasets will be useful in the production, refinement, and verification of statistical, ...
