The project aims to produce an atomic-resolution 3-D atlas of the photosynthetic machinery of single-cell green algae to guide the targeted engineering of high efficiency algae production cell lines and bio-inspired artificial solar fuel systems. Photosynthesis drives the first step of all algae production processes by capturing solar energy and converting it to chemical energy (for example sustainable fuels, food and high value products), but excess light can cause photodamage. Microalgae have evolved intricate photo-protection mechanisms that can dissipate up to 90 per cent of the captured light energy. Fine-tuning the light harvesting complexes could considerably increase efficiency.

该项目旨在制作单细胞绿色藻类光合机制的原子分辨率三维图谱，以指导高效藻类生产细胞系和生物启发的人造太阳能燃料系统的定向工程。光合作用通过捕获太阳能并将其转化为化学能（例如可持续燃料，食品和高价值产品）来驱动所有藻类生产过程的第一步，但过量的光线会导致光损伤。微藻已经进化出复杂的光保护机制，可以耗散高达90%的捕获光能。微调捕光复合物可以显著提高效率。
