Screening of yeast co‐culture using crude hydrolysate for co‐fermentation of pentose and hexose

Juliana P. Sandri, Thais S. Milessi, Teresa C. Zangirolami, Solange I. Mussatto

Biofuels, Bioproducts and Biorefining > 17 > 6 > 1639 - 1653

The use of all sugars from biomass fractionation – that is, hexoses and pentoses – is essential to develop feasible processes in a biorefinery context. Hexoses are converted into different products by most microorganisms. The main issue is the conversion of pentoses, especially when mixed with hexoses. Improving sugar conversion in co‐fermentation is a major challenge, which was explored in this work...
