Marine picocyanobacteria of the Prochlorococcus and Synechococcus genera have been longtime considered as autotrophic organisms. However, compelling evidence published over the last 15 years shows that these organisms can use different organic compounds containing key elements to survive in oligotrophic oceans, such as N (amino acids, amino sugars), S (dimethylsulfoniopropionate, DMSP), or P (ATP). Furthermore, marine picocyanobacteria can also take up glucose and use it as a source of carbon and energy, despite the fact that this compound is devoid of limiting elements and can also be synthesized by using standard metabolic pathways. This review will outline the main findings suggesting mixotrophy in the marine picocyanobacteria Prochlorococcus and Synechococcus, and its ecological relevance for these important primary producers.

海洋微微蓝藻的混合营养：原绿球藻和聚球藻使用有机化合物。

原绿球藻属和聚球藻属的海洋微微蓝藻长期以来一直被认为是自养生物。然而，过去 15 年发表的令人信服的证据表明，这些生物体可以利用含有关键元素的不同有机化合物在寡营养海洋中生存，例如 N（氨基酸、氨基糖）、S（二甲基磺基丙酸，DMSP）或 P（ATP））。此外，海洋微微蓝细菌也可以吸收葡萄糖并将其用作碳和能量的来源，尽管这种化合物缺乏限制元素并且也可以通过使用标准代谢途径合成。本综述将概述表明海洋微微蓝藻原绿球藻和聚球藻混合营养的主要发现，及其与这些重要初级生产者的生态相关性。
