- Abstract
The production of erythritol and the erythritol yield from glucose by Torula sp. were improved, in increasing order, by supplementing with 10 mg MnSO4 ⋅ 4H2O l-1, 2 mg CuSO4 ⋅ 5H2O l-1, and both 10 mg MnSO4 ⋅ 4H2O l-1 and 2 mg CuSO4 ⋅ 5H2O l-1. Mn2+ decreased the intracellular concentration of erythritol, whereas Cu2+ increased the activity of erythrose reductase in cells. These results suggest that Mn2+ altered the permeability of cells, whereas Cu2+ increased the activity of erythrose reductase in cells.
