项目摘要

Carbon dioxide levels are increasing rapidly causing global warming. Despite the current efforts in place, scientists predict carbon dioxide levels will continue to rise and innovative methods to sequester carbon are needed. Approximately 2 billion years ago, microorganisms called cyanobacteria removed carbon dioxide from the atmosphere causing the great oxygen event that enabled life as we know it to be created. Can cyanobacteria again solve the crisis we are seeing today?Cyanobacteria capture a broad spectrum of light during photosynthesis enabling them to sequester carbon more effectively compared with plants or trees. Yet, energy transfer during photosynthesis does not occur effectively all the time. By applying an innovative, state-of-the-art analytical approach, we have for the first time identified a mechanism within cyanobacteria's light-harvesting machinery that the organism uses to limit energy transfer during photosynthesis, thus rendering photosynthesis inefficient. Using an inter-disciplinary team of molecular biologists, structural biologists, analytical chemists and experts in photophysics, this proposal seeks to determine the precise role of this newly found molecular switch within cyanobacteria and use this knowledge to engineer cyanobacteria with enhanced photosynthetic properties for use by the renewable energy industries to enhance carbon sequestration.

二氧化碳水平正在迅速增加，导致全球变暖。尽管目前采取了努力，科学家预测二氧化碳水平将继续上升，需要隔离碳的创新方法。大约20亿年前，称为蓝细菌的微生物从大气中除去了二氧化碳，从而导致了巨大的氧气事件，从而使我们所知道的生命产生了生命。蓝细菌能否再次解决我们今天看到的危机？蓝细菌在光合作用过程中捕获了广泛的光，从而使它们能够与植物或树木相比更有效地隔离碳。然而，光合作用期间的能量传递并非始终发生。通过采用创新的，最先进的分析方法，我们首次确定了蓝细菌轻度收获机制中的一种机制，该机制在光合作用过程中用来限制能量传递，从而使光合作用效率低下。该建议使用分子生物学家，结构生物学家，分析化学家和专家的跨学科团队，该提议旨在确定这种新发现的氰基细菌中这种新发现的分子开关的精确作用，并将这些知识用于工程cyanobacteria，并具有增强光合作用的序列能量，以增强可恢复的光合作用，以增强可恢复的光合作用。
