D-Arabitol Production by Endomycopsis chodati

Forest Products Laboratory,¹ Forest Service, U.S. Department of Agriculture, Madison, Wisconsin

ABSTRACT

Endomycopsis chodati in an aerated fermentation produced D-arabitol in yields of 35 to 40% of the sugar supplied. Glucose, mannose, and sucrose were suitable substrates. A synthetic medium was developed for the fermentation that showed that nitrogen in the medium must be limiting to obtain high yields of arabitol. Excess phosphate also tended to lower arabitol yields, although the effect was not so great as with nitrogen. Pilot plant-size fermentations were made in which all the nutrients were supplied by blackstrap molasses and urea. Arabitol yields in these fermentations were about 40% of the sugar supplied.
