Sažetak
Several aspects concerning the bioconversion of xylose-containing hydrolysates (obtained from Eucalyptus wood) into xylitol were assessed. Debaryomyces hansenii yeast strains were adapted to fermentation media (obtained either by prehydrolysis or autohydrolysis- posthydrolysis of wood) supplemented with low-cost nutrients. Media containing up to 80 g/L xylose were efficiently fermented when the hydrolysates were detoxified by charcoal adsorption and supplemented with corn steep liquor.
