The system developed by the group of MA Yanhe is based on the construction of a mutant library of Pichia anomala followed by protoplast fusion of fluorescence-labeled mutants and a chromogenic assay for high sugar alcohol producers. High-performance producers of D- arabitol, D-ribitol or D-xylitol from glucose or xylose were obtained, with maximum yields of 0,77 g/g sugar.
