Title:
VARIANT WITH HIGH ERYTHRITOL PRODUCTIVITY AND PROCESS FOR PRODUCING ERYTHRITOL
Document Type and Number:
WIPO Patent Application WO/1997/026323
Kind Code:
A1
Abstract:
A variant of Trichosporonoides oedocephalis having characteristics of achieving a higher yield of erythritol on the basis of sugar and a lower cell productivity, each than that of the parent strain, at a sugar concentration of 30 W/V % or above but less than 60 W/V %; and a process for producing erythritol which comprises incubating the variant in a medium having a sugar concentration of from 20 to 50 W/V % and taking up the erythritol thus accumulated in the medium. Thus, erythritol can be efficiently produced on an industrial scale with the use of the strain having a high erythritol productivity.
