Relations between \( {\updelta \mathrm{D}}_{{\mathrm{H}}_2\mathrm{O}} \) and \( {\upalpha^{\mathrm{H}}}_{{\mathrm{CH}}_4\hbox{--} {\mathrm{H}}_2\mathrm{O}} \) values in the two coculture experiments (TC and MC). For TC batches, the \( {\updelta \mathrm{D}}_{{\mathrm{H}}_2\mathrm{O}} \) (and \( {\upalpha^{\mathrm{H}}}_{{\mathrm{CH}}_4\hbox{--} {\mathrm{H}}_2\mathrm{O}} \)) values calculated from the measured \( {\updelta \mathrm{D}}_{{\mathrm{H}}_2} \) values and the H2–H2O isotope fractionation factor at the temperature are also illustrated for comparison
