项目摘要

With fossil fuel supplies decreasing and global warming effects growing, solar energy is increasingly in demand. However, current solar panel efficiency is low with solar panels on most homes in the UK operating at only 15-20% efficiency. Red microalgae, in contrast, achieve 95% efficiency through their photosynthetic machinery, termed phycobilisomes. Harnessing these molecular systems for renewable energy applications has tremendous potential for the biotechnological industry. However, first we need to know what these phycobilisomes are made of and, thus, what makes these biological machines operate with such high efficiency.This research proposal will, for the first time, use state-of-the-art mass spectrometry to characterise the phycobilisome in red microalgae. By addressing this research question from an entirely new angle, we will deepen our understanding of how the phycobilisome is constructed. The phycobilisome efficiency will be altered by changing the light conditions during microalgae growth. By tracking the structural features of the phycobilisome with photosynthetic efficiency, we will determine the critical factors that are necessary for efficient light transmission and as such determine which phycobilisome composition is the most efficient for photosynthesis. The findings of which are essential to allow us to construct these highly efficient microscopic machines for incorporation into solar panel devices. The results of this proposal will have broad impact in the academic community amongst structural biologists, mass spectrometrists and within the solar energy and microalgae communities, with any knowledge gained being rapidly translatable for industrial use.

随着化石燃料供应的减少和全球变暖的影响，太阳能的需求越来越大。但是，目前的太阳能电池板效率较低，英国大多数房屋的太阳能电池板的效率仅为15-20％。相比之下，红色微藻通过其光合作用机制可实现95％的效率，称为植物质体。利用这些分子系统用于可再生能源应用对生物技术行业具有巨大的潜力。但是，首先，我们需要知道这些植物质体是由什么制成的，因此，是什么使这些生物机器以如此高的效率运行。这项研究提案将首次使用最先进的质谱法来表征红色微型植物中的植物质体。通过从一个全新的角度解决这一研究问题，我们将加深对植物剂的构建方式的理解。在微藻生长过程中改变光条件将改变植物质体的效率。通过跟踪具有光合作用效率的植物质体的结构特征，我们将确定有效的光传输所必需的关键因素，因此确定哪种植物质体组成是最有效的光合作用。其中的发现对于让我们能够构造这些高效的显微镜机器将其纳入太阳能电池板设备至关重要。该提案的结果将对结构生物学家，质谱学家以及太阳能和微藻社区内的学术界产生广泛的影响，任何知识都可以迅速转化用于工业用途。
