摘要

从日本千叶含几丁质土壤中分离到一株能将d -氨基葡萄糖(D-GlcN)氧化为d -氨基葡萄糖酸(D-GlcNA)的菌株a -10。经16S rRNA同源性和一些生理试验鉴定该菌株为不动杆菌。液体培养基中的D-GlcN在48h内消失，D-GlcNA在培养基中积累。值得注意的是，在D-GlcN的基础上，glcn的产率最高可达92 mol%。分离得到的D-GlcNA的FT-IR光谱与市售的D-GlcNA基本一致。

D-グルコサミンからD-グルコサミン酸への微生物変換

Strain A-10, which oxidizes D-glucosamine (D-GlcN) to D-glucosaminic acid (D-GlcNA), was isolated from a chitincontaining soil in Chiba, Japan. The strain was identified as Acinetobacter sp. by the 16S rRNA homology and some physiological tests. D-GlcN in the liquid medium disappeared within 48h, and D-GlcNA was accumulated in the medium. It is remarkable that the maximum yield of GlcNA reached 92 mol% based on D-GlcN. The FT-IR specrum of the isolated D-GlcNA was in fair agreement with the commercial D-GlcNA.
