BIODIVERSITY AND THE APPLICATION OF BLACK YEASTS IN ERYTHRITOL PRODUCTION
This study isolated erythritol - producing yeast strains. A total of 161 strains of the black yeasts were isolated from dust scattered samples and pollens. Twelve yeast strains of the genus Moniliella produced erythritol, among which strain 63.199 produced erythritol in good yields. This strain was good grown in a medium containing 30% glucose, at pH 6 and temperate 30oC. We used thin layer chromatography (TLC), high performance liquid chromatography (HPLC) and optical density (OD) method to analyse erythritol in the culture. After 9 days cultured, the strain 63.199 has high erythritol yield should be able to use it for further researchs.
