一些产物由需要赖氨酸的大肠杆菌 A.T.C.C. 培养物分泌。对在赖氨酸限制条件下生长的 12408 进行了研究。由此类生物体的培养滤液制备称为“细胞外脂糖肽”的糖脂。它含有 35% 的脂质、19% 的碳水化合物、3.4% 的 P 和 3.7% 的 N。将该脂糖肽的脂质、脂肪酸、碳水化合物和氨基酸与全细胞、细胞壁和细胞脂多糖的脂质、脂肪酸、碳水化合物和氨基酸进行比较表明，它与任何这些级分几乎没有共同的特征（除了其残留脂质）。脂糖肽与壁和脂多糖均具有抗原相关性。
Some of the products excreted by cultures of ly sine-requiring E. coli A.T.C.C. 12408 grown under lysine-limiting conditions have been studied. A glycolipid designated "extracellular lipoglycopeptide" was prepared from culture filtrates of such organisms. It contained 35% of lipid, 19% of carbohydrate, 3.4% of P and 3.7% of N. Comparison of the lipids, fatty-acids, carbohydrates and amino-acids of this lipoglycopeptide with those of whole cells, cell walls and cellular lipopolysaccharides shows that it has few features (except its residual lipids) in common with any of these fractions. The lipoglycopeptide was antigenically related to both walls and lipopolysaccharide.
