Lipoteichoic acid (LTA) and deacylated lipoteichoic acid have been isolated from the bovine-rumen Gram-negative anaerobe Butyrivibrio fibrisolvens by phenol extraction. Lipoteichoic acid (21.8 mumol phosphorus/g cells) consisted of a conventional 1, 3-phosphodiester-linked chain of glycerol phosphate units joined covalently to a glycolipid. It was not substituted with glycosyl or D-alalyl ester groups. Deacylated lipoteichoic acid (57.5 mumol phosphorus/g cells) was similar in constitution but lacked fatty acid esters. Lipoteichoic acid reacted serologically with antisera to the glycerol phosphate backbone of known lipoteichoic acids. The presence of similar teichoic acid polymers has also been demonstrated in some other strains of B. fibrisolvens and this is of significance in demonstrating that teichoic acids can occur in Gram-negative bacteria.
通过苯酚萃取法从牛瘤胃革兰氏阴性厌氧菌溶纤维丁酸弧菌中分离出脂磷壁酸（LTA）和去酰基脂磷壁酸。脂磷壁酸（21.8微摩尔磷/克细胞）由一条常规的1,3-磷酸二酯键连接的甘油磷酸单元链组成，该链与一种糖脂共价连接。它没有被糖基或D-丙氨酰酯基团取代。去酰基脂磷壁酸（57.5微摩尔磷/克细胞）在组成上相似，但缺乏脂肪酸酯。脂磷壁酸与已知脂磷壁酸甘油磷酸主链的抗血清发生血清学反应。在其他一些溶纤维丁酸弧菌菌株中也证实了类似磷壁酸聚合物的存在，这对于证明磷壁酸可以存在于革兰氏阴性细菌中具有重要意义。
