Gram-negative bacteria exhibit lipopolysaccharides (LPSs) on their outer membrane surface. LPS is considered one of the most potent bacterial virulence factors. Here we report the elucidation of the LPS O-chain structure isolated from Burkholderia fungorum, a bacterium isolated from the white-rot fungus Phanerochaete chrysosporium that can act as a pathogen for plants and domesticated animals. The structure was determined by the employment of detailed chemical and NMR spectroscopy analyses as the following.
革兰氏阴性菌在其外膜表面呈现脂多糖（LPSs）。LPS被认为是最有效的细菌毒力因子之一。在此，我们报告了从伯克霍尔德氏菌中分离出的LPS O链结构的解析，该细菌是从白腐真菌黄孢原毛平革菌中分离得到的，它可作为植物和家畜的病原体。该结构通过详细的化学和核磁共振光谱分析确定如下。
