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![thinsp](/content/j151895465112285/xxlarge8201.gif) ![sdot](/content/j151895465112285/xxlarge8901.gif) 4H2O l–1, 2 mg CuSO4![thinsp](/content/j151895465112285/xxlarge8201.gif) ![sdot](/content/j151895465112285/xxlarge8901.gif) 5H2O l–1, and both 10 mg MnSO4![thinsp](/content/j151895465112285/xxlarge8201.gif) ![sdot](/content/j151895465112285/xxlarge8901.gif) 4H2O l–1 and 2 mg CuSO4![thinsp](/content/j151895465112285/xxlarge8201.gif) ![sdot](/content/j151895465112285/xxlarge8901.gif) 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. |
