Current phytoplankton ecological theory is derived primarily from lab cultures, but in nature phytoplankton have unique microbiomes that support their growth and ongoing ocean primary production. This project aims to establish the structure and function of these natural microbiomes, and how they contribute to seafood poisoning caused by bacteria and algal biotoxins. Using advanced flow cytometry with single-cell microbial profiling, we will sample nano-scale plankton microbiomes and synthetic microbiome phylogenomics to the link between microbiomes and seafood poisoning outbreaks. The outcomes will underpin enhanced predictive modelling of seafood risk to ensure the safety and export security of Australia's $2 billion seafood industry.

目前的浮游植物生态理论主要来自实验室培养，但在自然界中，浮游植物具有独特的微生物组，支持它们的生长和持续的海洋初级生产。该项目旨在确定这些天然微生物组的结构和功能，以及它们如何导致细菌和藻类生物毒素引起的海鲜中毒。使用先进的流式细胞术和单细胞微生物分析，我们将对纳米尺度的浮游生物微生物组和合成微生物组进行采样，以研究微生物组与海鲜中毒爆发之间的联系。研究结果将加强海产品风险的预测模型，以确保澳大利亚20亿澳元海产品行业的安全和出口保障。
