蓝细菌是一类具有光合作用的原核生物，在全球地球化学中具有重要的影响力，是一种具有工业应用前景的生物。由于蓝细菌的生计直接依赖于光，因此对这些生物体中代谢的全面了解需要考虑昼夜转换和昼夜节律调节的影响。这些事件使细胞内的过程与太阳日同步。因此，代谢的控制和结构不同，在蓝藻比异养细菌。因此，适用于工程异养细菌的方法将需要修改蓝藻底盘。在这里，我们总结了重要的发现有关的昼夜代谢的蓝藻和目前在该领域的开放性问题。
Cyanobacteria are photosynthetic prokaryotes that are influential in global geochemistry and are promising candidates for industrial applications. Because the livelihood of cyanobacteria is directly dependent upon light, a comprehensive understanding of metabolism in these organisms requires taking into account the effects of day–night transitions and circadian regulation. These events synchronize intracellular processes with the solar day. Accordingly, metabolism is controlled and structured differently in cyanobacteria than in heterotrophic bacteria. Thus, the approaches applied to engineering heterotrophic bacteria will need to be revised for the cyanobacterial chassis. Here, we summarize important findings related to diurnal metabolism in cyanobacteria and present open questions in the field.
