Phytol has been separated and identified in the unsaponifiable lipid fraction from wild type Rhodopseudomonas spheroides, but it was not detected in mutant strains blocked at various stages of bacteriochlorophyll synthesis. Incorporation of (14)C-acetate into phytol paralleled bacteriochlorophyll synthesis in suspensions of the wild type incubated anaerobically in the light. The addition of chloramphenicol inhibited both processes. It is concluded that phytol formation is tightly coupled to the synthesis of the pyrrole component of bacteriochlorophyll.
植物醇已从野生型球形红假单胞菌的不可皂化脂质部分中分离和鉴定出来，但在各种阶段的细菌叶绿素合成受阻的突变体菌株中未检测到。（14）C-乙酸盐掺入植物醇与野生型菌悬液在光照下厌氧培养时细菌叶绿素的合成平行。加入氯霉素抑制了这两个过程。因此，可以得出结论，植物醇的形成与细菌叶绿素吡咯部分的合成紧密偶联。
