The present invention relates to a fermentation process to have a high productivity with a novel mutant of Pichia sp., more specifically, for preparing erythritol under optimal fermentation conditions for maximum erythritol production by optimizing the environmental conditions of culture such as pH, temperature and by controlling osmotic pressure. A two-stage fermentation was performed to control osmotic pressure. Osmotic pressure was adjusted to a low level during growth phase and to a relatively high level during production phase by adding continuously glucose and NaCl or KCl. Therefore, erythritol production could be increased.

Mutant cells of Pichia

The present invention relates to a fermentation process to have a high productivity with a novel mutant of Torula sp. DS101 (KCMM-10171), more specifically, for preparing erythritol using mother liquor produced from purification process, which comprises 30&tilde;60% of trehalulose, 10&tilde;30% of palatinose, 5&tilde;15% of fructose, 5&tilde;25% of glucose and 0&tilde;10% of sucrose.

The present invention relates to a fermentation process for preparing erythritol with high productivity with novel mutant of Trigonopsis variabilis, more specifically, for preparing erythritol under optimal fermentation conditions for maximum erythritol production by optimizing the environmental conditions of culture such as pH, temperature and controlling osmotic pressure. A two-stage fermentation was performed to control osmotic pressure. Osmotic pressure was adjusted to a low level during growth phase and to a high level during production phase by adding glucose and NaCl. Therefore, erythritol production could be increased due to the increased mutant cells.
