Abstract

Lipopolysaccharide from Moraxella bovis was isolated and its components characterized by paper and gas-liquid chromatography and mass spectrometry. The endotoxin showed a small amount of protein and contained 2-keto-3-deoxyoctonic acid glucose, mannose, glucosamine, heptose and phosphate. Six fatty acids (palmitic, palmitoleic, margaric, stearic, oleic and arachidic acids) were also identified. Margaric acid was the most prevalent fatty acid present in the lipid fraction.

摘要

从牛莫拉菌中分离出脂多糖，并通过纸色谱、气液色谱和质谱对其成分进行了表征。内毒素显示含有少量蛋白质，包含2-酮-3-脱氧辛酸、葡萄糖、甘露糖、氨基葡萄糖、庚糖和磷酸盐。还鉴定出六种脂肪酸（棕榈酸、棕榈油酸、十七烷酸、硬脂酸、油酸和花生酸）。十七烷酸是脂质部分中最普遍存在的脂肪酸。
