Additional file 2: of Hydrogen and carbon isotope systematics in hydrogenotrophic methanogenesis under H2-limited and H2-enriched conditions: implications for the origin of methane and its isotopic diagnosis

All results. Description of data: Batch culture names, sampling times (h; hours or d; days), hydrogen concentration (Pa), methane concentration (kPa), hydrogen isotope ratio of H2O, H2, and CH4 (‰ vs. VSMOW), carbon isotope ratio of CO2 and CH4 (‰ vs. VPDB), values of equilibrated hydrogen isotope ratio of H2 ( δ eq D H 2 $$ {\updelta}^{\mathrm{eq}}{\mathrm{D}}_{{\mathrm{H}}_2} $$ ) between H2 and H2O, fractionation factors of the carbon isotope ratio between CH4 and CO2 ( α C C H 4 – C O 2 $$ {\upalpha^{\mathrm{C}}}_{{\mathrm{C}\mathrm{H}}_4\hbox{--} {\mathrm{C}\mathrm{O}}_2} $$ ), and fractionation factors of the hydrogen isotope ratio between CH4 and H2O ( α H C H 4 – H 2 O $$ {\upalpha^{\mathrm{H}}}_{{\mathrm{CH}}_4\hbox{--} {\mathrm{H}}_2\mathrm{O}} $$ ). Cell numbers were counted only in the thermophilic pure culture batches. (XLSX 58 kb)
