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)

补充表S6. 宏基因组样本中主要产甲烷菌属与溶解性有机质（Dissolved Organic Matter, DOM）组成变化的显著相关性。本研究针对宏基因组样本中产甲烷菌的主要分类类群，与基于典型相关分析（Canonical Correlation Analysis, CCorA）得到的DOM组成第一典范轴的变化开展了皮尔逊相关系数检验。典型相关分析采用DOM组成的前5个主坐标轴（PCo1–5）与FOAM同源物的PCo1–2轴进行。分析得到两个典范轴（卡方检验，P<0.01），在此轴上观测到功能潜能与DOM组成间存在显著相关性（P<0.013）。本表格仅展示P<0.05的显著相关分类类群。MeNH2为甲胺。括号标注表示该底物可为部分（而非全部）物种或菌株所利用。（XLSX格式，文件大小12 KB）
