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。传统的环境清理方法往往由于将其大规模部署到自然环境中的复杂性而不足。我们迫切需要重新思考我们的战略。该项目旨在利用蓝藻的潜力-地球上最古老，最多样化的生物之一-解锁新方法。蓝藻在许多环境中普遍存在，由于其固氮和进行光合作用的能力，在基本的生态系统服务中发挥着至关重要的作用。但是，尽管人们对使用蓝藻进行生物修复的兴趣越来越大，但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以完成这项任务。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。为了实现这一目标，我们的项目围绕四个具体目标展开。首先，我们将致力于建造我们所说的“生态风洞”。这些我们可以在实验室里建立的人工生态系统，更好地模拟了真实的世界中复杂的时空组织和相互作用。通过使工程生物体经受这些更现实的条件，我们可以增强它们的功能，对它们在自然环境中的能力有更大的信心，并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，我们将使用大规模平行测定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，以促进重新编程蓝细菌的生物工具的快速开发。第三，为了确保我们的工程细胞在自然环境中的可追溯性，并促进其安全部署，我们将开发“条形码”我们的生物体的方法。这将使我们能够更好地跟踪它们的传播，并在商业环境中建立生物体的所有权。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，并改变它们的生物学特性，以简化它们从环境中的物理去除。这种以有针对性的方式去除我们的工程生物学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，因为它们只会暂时存在，而不会为它们提供足够的时间来嵌入。除了科学，我们还认识到在开发这项技术时，围绕可接受的使用与社会和政策制定者进行早期接触的关键作用。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，建立一个社区，并将举办包容性的活动，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一互动点来了解问题，沟通科学的循证风险和利益，并探索在环境背景下可接受地使用工程生物学的可能途径。总之，在这个项目中进行的科学和参与将有助于彻底改变污染控制策略，并启动新的可持续生物基环境修复解决方案。它还将开发关键的基础工具和方法，以降低将工程生物学部署到现实世界生态系统中的风险，并帮助建立蓝藻作为应对各种环境挑战的通用和安全平台。
