Fatty acids derived from Micrococcus cerificans growing at the expense of odd- and even-carbon normal alkanes were studied. Results demonstrated that cultures grown with a variety of nonhydrocarbon substrates serving as sole carbon and energy source yielded only even-carbon fatty acids. Even-chain alkanes, dodecane through octadecane serving as sole carbon source, resulted in even-carbon fatty acids with direct correlation between carbon number of the major fatty acid species and carbon number of the alkane substrate. Odd-carbon alkanes, undecane through heptadecane serving as sole carbon source, yielded both odd- and even-carbon fatty acids. A transitional shift from even-carbon fatty acids to odd-carbon fatty acids was observed as the carbon number of the alkane substrate increased. Unsaturated fatty acids were found to comprise a significant percentage of all profiles. Analysis of unsaturated fatty acids showed all odd- and even-carbon acids analyzed were Delta(9) monounsaturated fatty acids.
对以奇数和偶数碳正构烷烃为代价生长的微球菌衍生的脂肪酸进行了研究。结果表明，以多种非烃类底物作为唯一碳源和能源生长的培养物仅产生偶数碳脂肪酸。以十二烷至十八烷的偶链烷烃作为唯一碳源，产生了偶数碳脂肪酸，主要脂肪酸种类的碳数与烷烃底物的碳数之间存在直接相关性。以十一烷至十七烷的奇碳烷烃作为唯一碳源，产生了奇数和偶数碳脂肪酸。随着烷烃底物碳数的增加，观察到从偶数碳脂肪酸到奇数碳脂肪酸的过渡转变。发现不饱和脂肪酸在所有图谱中占很大比例。对不饱和脂肪酸的分析表明，所有分析的奇数和偶数碳酸均为Δ(9)单不饱和脂肪酸。
