Biogas isotope composition dynamics. The isotope signatures were plotted according to δ13C (a) and δ2H (c) of methane and δ13C of carbon dioxide (b) along the experiment with different inoculation strategies and digestion setups. The error bars with the standard errors are shown with the confidence interval of 95 % for the δ13C values and 65 % for the δ2H values
