Abstract
- Some members of the genus Butyrivibrio, including a general fatty acid auxotroph (strain S2), contain as a major part of their complex lipids a high-molecular-weight component that is probably formed by the union of two fatty acid chains [Hazlewood & Dawson (1979) J. Gen. Microbiol. 112, 15--27]. 2. Proton and 13C n.m.r. and i.r. and mass spectroscopy were used to examine a homologous series of these moieties and, in addition, the hydrocarbon derivative of one homologue and several synthetic compounds. 3. The results indicate that the high-molecular-weight components are a series of long-chain dicarboxylic acids containing vicinal dimethyl branching, located near the centre of the chain.
摘要
- 丁酸弧菌属的一些成员，包括一种普通脂肪酸营养缺陷型菌株（菌株S2），其复合脂质的主要部分含有一种高分子量成分，该成分可能由两条脂肪酸链结合而成[黑兹尔伍德和道森（1979年）《普通微生物学杂志》112卷，第15 - 27页]。2. 利用质子和碳-13核磁共振、红外光谱和质谱对这些部分的同系物系列进行了研究，此外还研究了一种同系物的烃衍生物和几种合成化合物。3. 结果表明，高分子量成分是一系列含有邻位二甲基支链的长链二元羧酸，支链位于链的中心附近。
