Biotransformation of L-arabinose to arabitol by selected yeasts was described. P. stipitis CCY 39501, P. guilliermondii DSM 70052, C. shehatae 3504, C. shehatae ATCC 22984, C. pseudotropicalis IPF 65, C. parapsilosis DSM 70125 were investigated to produce L-arabitol. C. parapsilosis DSM 70125 was the best producer of arabitol that was detected in concentrations 10-14 gdm-3 in the medium. The highest yield (0,78 gg-1) and productivity (0,036 g(gxh)-1) were also obtained for this strain. The other quite good producers of arabitol were P. guilliermondii DSM 70052 and C. shehatae ATCC 22984 that produced poliol with yields 0,43 gg-1 and 0,50 gg-1, respectively, in optimal conditions. Rotation conditions of shaker on the level 150 rpm and temperature of incubation 28C were selected to be optimal for biotransformation by all yeasts.
