The unicellular blue-green bacterium Agmenellum quadruplicatum strain BG-1 was found to be capable of rapid photoheterotrophic growth but unable to grow in the dark on a variety of reduced organic substrates. The generation time on glycerol was 12 h, and on CO(2), 3 h. Glycerol carbon was converted into cellular carbon with a very high efficiency. This high efficiency of carbon conversion, the action spectrum for growth on glycerol, cell pigmentation, gas exchange measurements, and immediate ability of photoheterotrophically grown cells to evolve O(2) (upon the addition of CO(2)) suggest the involvement of both photosystems I and II of photosynthesis during photoheterotrophic growth.
单细胞蓝细菌四聚鱼胞菌BG-1菌株被发现能够进行快速光异养生长,但无法在黑暗中利用多种还原态有机底物生长。在甘油上的代时为12小时,在CO₂上为3小时。甘油碳以非常高的效率转化为细胞碳。这种高碳转化效率、在甘油上生长的作用光谱、细胞色素沉着、气体交换测量以及光异养生长的细胞(添加CO₂后)立即释放O₂的能力表明,光合作用的光系统I和II在光异养生长过程中均有参与。
