Vjnelandii固氮菌产生一种部分乙酰化的胞外多糖，主要由D-甘露糖酸单元和少量L-古糖醛酸单元组成。它类似于海藻酸，因为它含有4-O连接的甘露糖残基和4-O和(或)5-O连接的古龙糖残基。细菌海藻酸钠的比旋光度与其藻类对应物的比旋度相近，表明其糖苷构型相似。
Azotobacter vjnelandii produces a partly acetylated exocellular polysaccharide which consists mainly of D-mannuronic acid units and a small proportion of L-guluronic acid units. It resembles alginic acid since it contains 4-O-linked mannuronosyl residues and guluronosyl residues which are 4-O- and (or) 5-O-linked. The specific rotation of bacterial sodium alginate is close to that of its algal counter -part, thus suggesting that the glycosidic configurations are similar.
