Under dark, anaerobic conditions in the presence of sufficient nickel, Rhodospirillum rubrum grows with a doubling time of under 5 h by coupling the oxidation of CO to the reduction of H+ to H2. CO-dependent growth of R. rubrum UR294, bearing a kanamycin resistance cassette in cooC, depends on a medium nickel level ninefold higher than that required for optimal growth of coo+ strains.
在黑暗、厌氧且存在足够镍的条件下,深红红螺菌通过将一氧化碳的氧化与氢离子还原为氢气相偶联,以不到5小时的倍增时间生长。深红红螺菌UR294的cooC基因中带有卡那霉素抗性盒,其依赖一氧化碳的生长所需的培养基镍水平比coo⁺菌株最佳生长所需的镍水平高九倍。
