Environmental pollution threatens the sustainability of the world's oceans. However, we still do not understand how pollution affects primary producers at the base of oceanic food chains. This project aims to provide the first account of how common chemical pollutants (herbicides, plastic leachates and crude oil) affect key groups of marine photosynthetic bacteria. As these microbes underpin entire marine food webs, understanding their responses is crucial to monitoring and mitigating the impact of pollutants on ocean ecosystems. The aim is to design and validate novel, rapid environmental stress assays, based on gene expression profiling. This represents a pioneering new application of gene monitoring techniques to ocean conservation.

环境污染威胁着世界海洋的可持续性。然而，我们仍然不了解污染如何影响海洋食物链基础的初级生产者。该项目旨在首次说明常见化学污染物（除草剂、塑料沥滤物和原油）如何影响海洋光合细菌的关键群体。由于这些微生物支撑着整个海洋食物网，因此了解它们的反应对于监测和减轻污染物对海洋生态系统的影响至关重要。其目的是设计和验证新的，快速的环境压力测定，基于基因表达谱。这是基因监测技术在海洋保护方面的一个开创性的新应用。
