Table S6. Significant correlations between major methanogen genera in the metagenomic samples and the compositional change of DOM. Pearson’s correlation coefficient tests were performed between major taxonomic groups of methanogens in the metagenomic samples and the compositional change of DOM along first canonical axis obtained from canonical correlation analysis (CCorA). CCorA was performed using the first five principal coordinate (PCo1–5) axes of DOM composition and PCo1–2 axes of FOAM orthologs. It resulted in two canonical axes (P < 0.01, chi-square test) along which significant correlations were observed between functional potentials and DOM composition (P < 0.013). Only taxa with significant correlations (P < 0.05) were shown here. MeNH2 is methylamine. Parentheses means utilized by some, but not all species or strains. (XLSX 12 kb)

表S6 宏基因组样本中主要产甲烷古菌属与溶解态有机物（Dissolved Organic Matter, DOM）组成变化间的显著相关性。本研究针对宏基因组样本中主要产甲烷古菌分类群，与通过典型相关分析（Canonical Correlation Analysis, CCorA）得到的DOM组成沿第一典范轴的变化量开展皮尔逊相关系数检验。本次典型相关分析以DOM组成的前5个主坐标轴（PCo1–5）与FOAM同源基因的前2个主坐标轴（PCo1–2）作为输入变量进行构建。分析最终得到2个典范轴（卡方检验，P<0.01），在该类典范轴上可观测到微生物功能潜力与DOM组成间存在显著相关性（P<0.013）。本表格仅展示相关性达到显著水平（P<0.05）的产甲烷古菌分类群。MeNH2即甲胺。表格中括号标注的含义为：部分而非全部物种或菌株可利用该底物。（XLSX格式，文件大小12 kb）
