项目摘要
Pollution is one of the most pressing global challenges of today, threatening our ecosystems, health, and wellbeing. Traditional approaches to environmental clean-up often fall short due to the complexity of deploying them at scale into natural environments. There is an urgent need to rethink our strategy. This project aims to harness the potential of cyanobacteria - one of the oldest and most diverse organisms on Earth - to unlock new approaches. Cyanobacteria are ubiquitous in many environments and play a crucial role in basic ecosystem services due to their ability to fix nitrogen and perform photosynthesis. But despite a growing interest in the use of cyanobacteria for bioremediation, we currently lack reliable biological parts and experimental tools to safely reprogram cyanobacteria for this task. In this project we propose a multidisciplinary effort to overcome these hurdles and make engineered cyanobacteria a feasible platform for restoration of degraded environments. To archive this, our project is built around four specific objectives. First, we will aim to construct what we term "ecological wind tunnels". These artificial ecosystems that we can build in the lab, better mimic the complex spatial-temporal organization and interactions found in the real world. By subjecting engineered organisms to these more realistic conditions, we can enhance their functionality, have greater confidence in their ability to perform in natural environments, and evaluate their ecological impact more accurately than in a typical lab setting. Second, we will use massively parallel assays and sequencing-based surveillance techniques, combined with rigorous measurements and advanced artificial intelligence, to facilitate the rapid development of biological tools for reprogramming cyanobacteria. Third, to ensure the traceability of our engineered cells in natural environments and facilitate their safe deployment, we will develop approaches to "barcode" our organisms. This will enable us to better track their dispersal and establish ownership of the organisms in commercial contexts. Finally, as a case study, we will engineer cyanobacteria that are able to naturally absorb various pollutants from the environment and alter their biology to simplify their physical removal from the environment. This ability to remove our engineered biology in a targeted way will help to reduce any long-term impact our cells have on a natural ecosystem by allowing them to only be present temporarily and not provide sufficient time for them to become embedded.In addition to the science, we also recognise the crucial role of early engagement with society and policy makers around the acceptable use of this technology as it is developed. We have therefore partnered with a range of leading academics, companies, non-profit organisations, and funders to build a community and will hold inclusive events that connect our science to wider society and decision makers in government. We aim to use this point of interaction to understand concerns, communicate evidence-based risks and benefits regarding the science, and explore possible routes towards the acceptable use of engineered biology in environmental contexts.Together, the science and engagement performed in this project will help revolutionize pollution control strategies and kick-start new sustainable bio-based solutions to environmental restoration. It will also develop the crucial foundational tools and methods needed to de-risk the deployment of engineered biology into real-world ecosystems and help to establish cyanobacteria as a versatile and safe platform for tackling diverse environmental challenges.
污染是当今最紧迫的全球挑战之一,威胁着我们的生态系统、健康和福祉。由于在自然环境中大规模部署这些方法的复杂性,传统的环境清理方法往往效果不佳。我们迫切需要重新考虑我们的战略。该项目旨在利用蓝藻的潜力-地球上最古老和最多样化的生物之一-解锁新的方法。蓝藻在许多环境中普遍存在,由于它们具有固定氮和进行光合作用的能力,在基本生态系统服务中起着至关重要的作用。但是,尽管对使用蓝藻进行生物修复的兴趣越来越大,我们目前缺乏可靠的生物部件和实验工具来安全地重新编程蓝藻来完成这项任务。在这个项目中,我们提出了一个多学科的努力,以克服这些障碍,使工程蓝藻一个可行的平台,恢复退化的环境。为了实现这一点,我们的项目围绕四个特定目标构建。首先,我们将致力于建设我们所说的“生态风洞”。我们可以在实验室里建立这些人工生态系统,更好地模拟现实世界中复杂的时空组织和相互作用。通过将工程生物置于这些更现实的条件下,我们可以增强它们的功能,对它们在自然环境中的表现能力更有信心,并且比在典型的实验室环境中更准确地评估它们的生态影响。其次,我们将使用大规模并行分析和基于测序的监测技术,结合严格的测量和先进的人工智能,促进蓝藻重编程生物工具的快速发展。第三,为了确保我们的工程细胞在自然环境中的可追溯性,并促进它们的安全部署,我们将开发对我们的生物体进行“条形码”的方法。这将使我们能够更好地跟踪它们的扩散,并在商业环境中建立生物的所有权。最后,作为一个案例研究,我们将设计能够自然吸收环境中各种污染物的蓝藻,并改变其生物特性,以简化其从环境中物理去除的过程。这种有针对性地去除我们的工程生物的能力,将有助于减少我们的细胞对自然生态系统的任何长期影响,因为它们只是暂时存在,没有足够的时间让它们嵌入其中。除了科学,我们还认识到,在这项技术开发过程中,尽早与社会和政策制定者接触,以使其得到可接受的使用,这是至关重要的。因此,我们与一系列领先的学者、公司、非营利组织和资助者合作,建立了一个社区,并将举办包容性活动,将我们的科学与更广泛的社会和政府决策者联系起来。我们的目标是利用这个互动点来理解关注的问题,交流基于证据的科学风险和利益,并探索在环境背景下可接受使用工程生物学的可能途径。在这个项目中,科学和参与将有助于彻底改变污染控制战略,并启动新的可持续的生物基础解决方案,以恢复环境。它还将开发关键的基础工具和方法,以降低工程生物学在现实世界生态系统中的部署风险,并帮助建立蓝藻作为应对各种环境挑战的多功能和安全平台。
