Increased erythritol production in Torula sp with inositol and phytic acid

Of the vitamins tested, inositol was the most effective for erythritol prod uction. To increase erythritol production by Torula sp., inositol and a rel ated compound, phytic acid (myoinositol hexaphosphate), were added to the c ulture media. Erythritol production in the presence of phytic acid was grea ter than that in the presence of inositol, due to the synergistic effects o f phosphate and inositol. Supplementation with phosphate and inositol incre ased cell growth, erythritol production, and the activity of erythrose redu ctase in cells. Inositol was a more effective stimulator of cell growth and erythritol production than was phosphate.
