Marine metabolomics: measurement of metabolites in seawater by gas chromatography mass spectrometry

One of the major bottlenecks in describing marine ecosystems is characterizing the metabolome of seawater, as salt prevents metabolite analysis. We present SeaMet, a method that can detect hundreds of metabolites in less than one mL of seawater and quantifies them down to nano-molar levels using gas chromatography-mass spectrometry. Our method provides a major advance in marine metabolomics by enabling the unbiased analysis of primary metabolites across saltwater habitats.

表征海水代谢组是描述海洋生态系统的核心瓶颈之一，因盐分会干扰代谢物分析。本研究提出SeaMet方法，该方法仅需不足1毫升的海水样本即可检出数百种代谢物，并借助气相色谱-质谱联用法（gas chromatography-mass spectrometry）实现纳摩尔级别的定量检测。本方法通过实现咸水环境中初级代谢物的无偏分析，为海洋代谢组学领域带来了重大进展。本数据集存储库包含与海洋生境研究相关的数据。
