Abstract
Abstract A process for the fermentative production of D-arabitol by cultivating under aerobical condition a micro-organism Pichia ohmeri No. 230 (ATCC Deposit No. 20209) in a nutrient medium containing fermentable saccharides such as glucose, sucrose, mannose, fructose and the like as carbon source, and recovering D-arabitol accumulated in the cultivated liquor. D-arabitol is thus obtained at a high yield without substantial formation of other polyhydric alcohols having similar properties.
