细菌胞外多糖中非碳水化合物取代基的出现已得到充分证明。乙酸盐和丙酮酸盐经常在同一多糖中单独或一起检测到1,2。最近，一种由粪产碱菌（Alcaligenes faecalis var.）分泌的多糖。 myxogenes 被证明含有琥珀酸 3。尽管甲酸被认为是一种细菌代谢物，但此前尚未报道过它是细菌胞外多糖的组成部分。这可能部分是因为缺乏合适的甲酸盐检测或估计方法，也因为已知 O-酰基对碳水化合物的不稳定性。
THE occurrence of non-carbohydrate substituents in bacterial exopolysaccharides has been well documented. Acetate and pyruvate have frequently been detected either separately or together in the same polysaccharide1,2. More recently, a polysaccharide secreted by Alcaligenes faecalis var. myxogenes was shown to contain succinate3. Although formate is known as a bacterial metabolite it has not previously been reported as an integral component of bacterial extracellular polysaccharides. This may be partly because of the lack of suitable methods for detection or estimation of formate and also because of the known lability of O-acyl groups on carbohydrates.
