Acinetobacter sp. strain M-1 accumulated a large amount of wax esters from an n-alkane under nitrogen-limiting conditions. Under the optimized conditions with n-hexadecane as the substrate, the amount of hexadecyl hexadecanoate in the cells reached 0.17 g/g of cells (dry weight). Electron microscopic analysis revealed that multilayered disk-shaped intracellular inclusions were formed concomitant with wax ester formation. The contribution of acyl-CoA reductase to wax ester synthesis was evaluated by gene disruption analysis.
不动杆菌属菌株M-1在氮限制条件下从正构烷烃中积累了大量蜡酯。在以正十六烷为底物的优化条件下,细胞中十六烷基十六烷酸酯的含量达到0.17 g/g细胞(干重)。电子显微镜分析表明,多层盘状细胞内包涵体是伴随蜡酯形成而形成的。通过基因敲除分析评估了酰基辅酶A还原酶对蜡酯合成的贡献。
