Flagellum formation by ubiquinone- and menaquinone-deficient mutant strains of Escherichia coli K-12 was studied under both aerobic and anaerobic growth conditions. Ubiquinone was found to be obligatory for aerobic flagellum formation but could be replaced by menaquinone for anaerobic flagellum formation. A mutant devoid of both quinones was immotile aerobically as well as anaerobically. Hence, the respective electron transport system is obligatory for flagellum formation in Escherichia coli.
在需氧和厌氧生长条件下,研究了大肠杆菌K-12泛醌和甲萘醌缺陷突变株的鞭毛形成情况。发现泛醌对于需氧条件下的鞭毛形成是必需的,但在厌氧条件下的鞭毛形成中,泛醌可被甲萘醌替代。一个同时缺乏这两种醌的突变体在需氧和厌氧条件下均无运动能力。因此,相应的电子传递系统对于大肠杆菌的鞭毛形成是必需的。
