Abstract
A high-yield bacterial strain for producing acetoin namedXH195 has been deposited in a microorganism deposit center in Germany. The deposit number is DSM 16187. The bacteria of the strain are rod-shaped, 1.5 μm to 3.0 μm in length, and 0.6 μm to 0.7 μm in diameter. The colony color of the bacterial strain is yellow or white. The strain has the typical fatty acid profile ofand its physiological and biochemical characteristics align with those of. When the bacteria of strain were cultured at 37° C. for 60 hours with shaking, the yield of acetoin could reach 63.0 g/L or 58.1 g/L, when glucose or sucrose was used as the substrate, respectively.
