珊瑚已经发展成为优化的光子增强系统，从而实现节省空间的微藻生长和出色的光合作用量子效率。藻类自遮光引起的光衰减是微藻养殖规模化的关键限制因素。受珊瑚启发的光管理系统可以克服这一限制，并促进可扩展的生物能源和生物产品的生产。在这里，我们开发了 3D 打印的仿生珊瑚，能够生长空间细胞密度高达 10(9)cellsmL(-1) 的微藻。这种混合光合生物材料是通过 3D 生物打印平台生产的，该平台以微米分辨率模拟活珊瑚组织和底层骨骼的形态特征，包括它们的光学和机械特性。因此，可编程的合成微环境可以复制珊瑚-藻类共生的结构和功能特征。我们的工作定义了一类仿生材料，能够与生物体相互作用，并可用于应用珊瑚礁研究和光生物反应器设计。珊瑚已经进化为精细调节的光收集器。在此，作者报告了受珊瑚启发的生物材料的 3D 打印，该材料模仿珊瑚-藻类共生；这些仿生珊瑚导致微藻密集生长，并可在藻类生物技术和应用珊瑚科学中找到应用。
Corals have evolved as optimized photon augmentation systems, leading to space-efficient microalgal growth and outstanding photosynthetic quantum efficiencies. Light attenuation due to algal self-shading is a key limiting factor for the upscaling of microalgal cultivation. Coral-inspired light management systems could overcome this limitation and facilitate scalable bioenergy and bioproduct generation. Here, we develop 3D printed bionic corals capable of growing microalgae with high spatial cell densities of up to 10(9)cellsmL(-1). The hybrid photosynthetic biomaterials are produced with a 3D bioprinting platform which mimics morphological features of living coral tissue and the underlying skeleton with micron resolution, including their optical and mechanical properties. The programmable synthetic microenvironment thus allows for replicating both structural and functional traits of the coral-algal symbiosis. Our work defines a class of bionic materials that is capable of interacting with living organisms and can be exploited for applied coral reef research and photobioreactor design. Corals have evolved as finely tuned light collectors. Here, the authors report on the 3D printing of coral-inspired biomaterials, that mimic the coral-algal symbiosis; these bionic corals lead to dense microalgal growth and can find applications in algal biotechnology and applied coral science.
