从腐烂的蔬菜中筛选到1株能发酵转化赤藓糖醇生产L-赤藓酮糖的菌株。基于形态学、生理生化鉴定及16S rRNA基因序列结果的分析,确定该菌属于醋酸杆菌科(Acetobacteraceae)葡萄糖酸杆菌属(Gluconobacter)kondonii,将其命名为HD385。进行初步发酵实验,该菌能以10%浓度的赤藓糖醇为底物发酵产生L-赤藓酮糖,产量达到82.9 g/L。

A strain producing L-erythrulose from erythritol was isolated from rotted vegetables. A series of analyses on morphological and biochemical characteristics and sequence analysis of 16 S rRNA revealed that it belonged to Gluconobacter kondonii,which named Gluconobacter kondonii HD385. A preliminary study on fermentation showed that the strain produced 82. 9 g / L of L-erythrulose using 10% erythritol in a medium as carbon source.
