Gluconacetobacter xylinus (=Acetobacter xylinum) ATCC 10245 incorporated 2-amino-2-deoxy-D-glucose (glucosamine) and 2-acetamido-2-deoxy-D-glucose (N-acetylglucosamine), but not 3-O-methyl-D-glucose or 2-deoxy-D-glucose into exopolymers. Incorporation was confirmed by gas chromatography with and without mass spectrometry, Fourier transform infrared, and 1H nuclear magnetic resonance. The average molar percentage of glucosamine and N-acetylglucosamine in the exopolymers was about 18%.
木醋杆菌(=醋化醋杆菌)ATCC 10245将2-氨基-2-脱氧-D-葡萄糖(葡糖胺)和2-乙酰氨基-2-脱氧-D-葡萄糖(N-乙酰葡糖胺)掺入胞外聚合物中,但不掺入3-O-甲基-D-葡萄糖或2-脱氧-D-葡萄糖。通过有无质谱的气相色谱法、傅里叶变换红外光谱法和1H核磁共振法证实了掺入情况。胞外聚合物中葡糖胺和N-乙酰葡糖胺的平均摩尔百分比约为18%。
