We isolated a mutant of Rhodopseudomonas spheroides that grows normally under photosynthetic conditions but is unable to grow exponentially under aerobic conditions. Photosynthetically grown cultures of the mutant increase in mass and cell number for about 10 hr after transfer to aerobic conditions. During this time, no heme pigments are synthesized and the Q(O(2)) declines. In the mutant, synthesis of heme pigments is obligatorily coupled to synthesis of bacteriochlorophyll.
我们分离出了球形红假单胞菌的一个突变体，该突变体在光合条件下能正常生长，但在有氧条件下无法指数生长。将该突变体光合培养的菌液转移至有氧条件后，其质量和细胞数量会增加约10小时。在此期间，没有合成血红素色素，并且氧摄取率下降。在该突变体中，血红素色素的合成必然与细菌叶绿素的合成相关联。
