光合生物对地球上的生命至关重要，因为它们提供食物和氧气，是大多数能源的基础。它们有各种各样的光收集策略，这使得它们几乎可以生活在阳光可以穿透的任何地方。它们已经使它们的色素沉着适应了它们栖息地的光谱组成，它们适应了缓慢变化的光强度，它们对光的质量和数量的快速变化做出了快速反应。这对产氧生物尤其重要，因为过量的光与氧结合可能是致命的。在了解不同的生物体如何最大限度地吸收光和最大限度地减少有害影响方面，正在取得迅速进展。在这里，我们总结了最新的发现，并解释了自然界中使用的主要设计原则。现有的知识可用于优化自然和人工光合作用的光收集，以改善光驱动生产过程。
Photosynthetic organisms are crucial for life on Earth as they provide food and oxygen and are at the basis of most energy resources. They have a large variety of light-harvesting strategies that allow them to live nearly everywhere where sunlight can penetrate. They have adapted their pigmentation to the spectral composition of light in their habitat, they acclimate to slowly varying light intensities and they rapidly respond to fast changes in light quality and quantity. This is particularly important for oxygen-producing organisms because an overdose of light in combination with oxygen can be lethal. Rapid progress is being made in understanding how different organisms maximize light harvesting and minimize deleterious effects. Here we summarize the latest findings and explain the main design principles used in nature. The available knowledge can be used for optimizing light harvesting in both natural and artificial photosynthesis to improve light-driven production processes.
