An acidic exopolysaccharide was isolated from P. fluorescens strain H13. The structure of the polysaccharide repeating unit was determined using chemical methods and 1D and 2D NMR techniques. The repeating unit was characterized as a trisaccharide composed of D-glucose, 2-acetamido-2-deoxy-D-glucose and 4-O-acetyl-2-acetamido-2-deoxy-D-mannuronic acid.
从荧光假单胞菌H13菌株中分离出一种酸性胞外多糖。使用化学方法以及一维和二维核磁共振技术确定了该多糖重复单元的结构。该重复单元被鉴定为一种由D-葡萄糖、2-乙酰氨基-2-脱氧-D-葡萄糖和4-O-乙酰基-2-乙酰氨基-2-脱氧-D-甘露糖醛酸组成的三糖。
