Coculture of xylose-fermenting yeast P. stipitis CCY 39501 and respiratory deficient mutant of S. cerevisiae V30 designated as V30 I 40 was used for ethanol fermentation on a medium containing glucose and xylose mixture and compared to P. stipitis monoculture or coculture of P. stipitis and S. cerevisiae V30. Batch fermentations were carried out on a model medium or on a medium containing both sugars derived from direct saccharification of either wheat straw or birch sawdust. The yields obtained were 0.38 g/g, 0.34 g/g and 0.4 g/g for model medium, wheat straw and birch sawdust hydrolysates respectively, after cofermentation of P. stipitis with RD mutant V30 I 40. The results confirmed the application of this coculture for ethanol fermentation of sugars derived from lignocellulosic hydrolysates.
