Table 2 Ethanol yield based solely on monomeric xylose of SR8A6S3-CDT-2 and SR8A6S3 strains under micro-aerobic cultivation at 30 °C in YP medium, supplemented with a mix of hemicellulosic hydrolysate plus xylose and acetate (YPXAH), hydrolysed xylan (YPXyl) or a mix of hydrolysed xylan plus acetate (YPAXyl) with varied initial OD600.
