METHOD FOR PREPARING ERYTHRITOL USING NOVEL TRIGONOPSIS VARIABILIS

摘要

The present invention is related to a fermentation process for the production of erythritol by using a novel strain teurigo high cis-foldRia Billy's(Trigonopsis variabilis) (Accession No. KCCM-10120 Ho). In particular, the production of erythritol by optimizing the environmental conditions such as pH, temperature, osmotic pressure in order to obtain the maximum erythritol production. In the present invention, a two-stage culture method was used to control the osmotic pressure. In other words, the high growth rate and high productivity of the product generator are maintained by maintaining the low osmotic environment in the cell growth period to increase the cell growth rate, and then adding potassium chloride and glucose to the increased concentration of the cells. It relates to a method for producing erythritol.
