## Abstract In the current study, a GRAS (Generally Recognized As Safe) strain of __Bacillus amyloliquefaciens__ producing 2,3βbutanediol (2,3βBD) designated as B10β127 was isolated in our lab. The strain B10β127 produced 2,3βBD effectively under the condition of 20% glucose (quality concentration)
Xylitol was produced as a metabolic by-product by a number of yeasts when grown on medium containing D-xylose as carbon and energy sources. Among the yeast strains tested, a mutant strain of Oandida tropicalis (HXP2) was found to produce xylitol from D-xylose with a high yield (>90%). Ethanol was a
