This project aims to reduce the impact of marine plastic pollution in South East Asia by understanding how microorganisms living on plastic surfaces affect the pollution threat and by exploring the potential of these microorganisms to provide a solution to the problem. SE Asian seas receive outputs from five of the top ten global emitters of plastic debris but there is little understanding of the threat to ecosystems and 650 million humans living in the region posed by 'plastispheres', the term used to describe the combination of plastic and the microorganisms that live on it. We need to characterise the microorganisms living on plastics in the sea and explore how they affect the breakdown of plastic. Through this we will understand how microorganisms transform plastic surfaces and determine the ultimate fate of plastic detritus in the marine environment. We need to measure the impact these plastispheres have on marine environments and wildlife in order to accurately characterise the hazard posed by plastispheres, and not just plastics, to the region's ecosystems. We will search for solutions to removing plastics and grow an informed and connected community of regional stakeholders in order to reduce environmental damage by current and future plastic pollution.This project coordinates the expertise of researchers from Singapore, UK, Indonesia,the Philippines and Vietnam to carry out laboratory and field experiments on microbial colonisation and transformation of plastic. We will analyse the DNA of biofilms and use microscopy to measure plastic degradation to identify the microorganisms living on the plastics and how they affect the plastic breakdown. We will quantify the volume, type and location of plastisphere loads in key habitats and animals to measure the impact plastispheres have on selected coastal ecosystems - mangroves, coral reefs and beaches. We will direct enzymes discovered in biofilms for use in bioengineered recycling, helping the transition towards a circular plastics economy in which waste plastic is intercepted before it enters the sea and is converted into useful products. We will coordinate with regional policy organisations and action groups to grow an informed and connected community of plastic stakeholders. We will conduct workshops to share expertise, disseminate our ideas and engage with stakeholders in order to develop solutions applicable to the SE Asian region. The project will give a novel perspective that shows how the threats from marine plastic are mediated by microorganisms, facilitating innovative solutions and enhancing regional governance of marine plastic pollution.

该项目旨在通过了解生活在塑料表面上的微生物如何影响污染威胁，并探索这些微生物的潜力来解决问题，从而减少东南亚海洋塑料污染的影响。东南亚海洋接收来自全球十大塑料垃圾排放国中五个的排放，但人们对“塑料球”对生态系统和生活在该地区的6.5亿人构成的威胁知之甚少，这个术语用来描述塑料和生活在塑料上的微生物的结合。我们需要研究生活在海洋塑料上的微生物，并探索它们如何影响塑料的分解。塑料通过这一研究，我们将了解微生物如何改变塑料表面，并决定塑料碎屑在海洋环境中的最终命运。我们需要测量这些塑料球对海洋环境和野生动物的影响，以便准确地评估塑料球（而不仅仅是塑料）对该地区生态系统造成的危害。我们将寻求去除塑料的解决方案，并发展一个由区域利益相关者组成的知情和联系的社区，以减少当前和未来塑料污染对环境的破坏。该项目协调来自新加坡，英国，印度尼西亚，菲律宾和越南的研究人员的专业知识，进行实验室和现场实验，研究微生物定植和塑料转化。我们将分析生物膜的DNA，并使用显微镜来测量塑料降解，以确定生活在塑料上的微生物以及它们如何影响塑料分解。我们将量化关键栖息地和动物中塑料球负载的数量，类型和位置，以衡量塑料球对选定的沿海生态系统-红树林，珊瑚礁和海滩的影响。我们将指导在生物膜中发现的酶用于生物工程回收，帮助向循环塑料经济过渡，在循环塑料经济中，废塑料在进入海洋之前被拦截并转化为有用的产品。我们将与区域政策组织和行动团体协调，以建立一个知情和相互联系的塑料利益相关者社区。我们将举办研讨会，分享专业知识，传播我们的想法，并与利益相关者合作，以制定适用于东南亚地区的解决方案。该项目将提供一个新的视角，展示海洋塑料的威胁是如何由微生物介导的，促进创新解决方案，并加强海洋塑料污染的区域治理。
