Abstract

Bishop, D. G. (University of Sydney, Sydney, Australia), and J. L. Still. Fatty acid metabolism in Serratia marcescens. J. Bacteriol. 82:370-375. 1961.-A study has been made of the oxidation of saturated fatty acids containing between two and 18 carbon atoms by whole cells of the bacterium, Serratia marcescens. This organism was found to be capable of oxidizing all of the acids tested, but variations in the rate and total oxygen uptake were found. These variations were dependent on the length of the carbon chain in the substrate molecule and the pH of the reaction mixture. The concept that these variations are due to a cellular permeability barrier to the substrate is discussed.

摘要

毕晓普,D.G.(澳大利亚悉尼大学,悉尼)和J.L.斯蒂尔。粘质沙雷氏菌中的脂肪酸代谢。《细菌学杂志》82:370 - 375。1961年。——对粘质沙雷氏菌全细胞氧化含2至18个碳原子的饱和脂肪酸进行了研究。发现该生物体能够氧化所有测试的酸,但在氧化速率和总耗氧量上存在差异。这些差异取决于底物分子中碳链的长度以及反应混合物的pH值。文中讨论了这些差异是由于细胞对底物存在渗透屏障这一观点。
