Publication protocol

The enzymatic activity of xylose reductase (XR) and xylitol dehydrogenase (XDH) in crude-cell extracts was measured according to [23]. For this, 5 mL of cell suspension of S. stipitis, S. passalidarum, S. arborariae and C. tenuis were collected in the middle of the exponential growth phase during aerobic and oxygen-limited fermentations. Cells were pelleted by centrifugation, washed with sterile water, and lysed with Y-PER®—Yeast Protein Extraction Reagent (Pierce, Rockford, USA) to obtain cell-crude extracts. Protein concentrations in cell-free extracts were determined using Quick StartTM Bradford Protein Assay Kit (Bio-Rad Laboratories Ltda., USA), following the manufacture’s instruction.
