Abstract:

One of the main problems limiting the economic production of ethanol from lignocellulosicbiomass is D-xylose fermentation. In a medium containing glucose and xylose, it is preferableto achieve conversion with glucose fermenting yeast like S. cerevisiae and xylose fermentingyeast like P. stipitis. In order to resolve this problem, it is better to use respiratory deficientmutants. In this research, respiratory deficient mutant strains S. cerevisiae V30 and Ja(a) wereobtained and their ability to ferment glucose in coculture with P. stipitis was investigated. Ahigher xylose conversion was observed in P. stipitis cultivation with these mutants because ofbetter oxygen conditions than in the culture with native S. cerevisiae. A degree of assimilatedxylose did not efficiently increased ethanol yields but on the other hand it increased the production of yeast biomass. Process conditions in relation to the fermentative performances usingdifferent strains combinations are discussed.
