Procedure for the regulation of buffer capacity in fermenting substrates comprises an unique expulsion of the available percarbonate quantity in the form of carbon dioxide and its volumetric measurement by the addition of acid. Procedure for the regulation of buffer capacity in fermenting substrates comprises an unique expulsion of the available percarbonate quantity in the form of carbon dioxide and its volumetric measurement by the addition of acid, where the acid is an organic- or inorganic acid, the acid is added in excess, the acid is proportioned one or more times, the carbon dioxide is determined by volumetric procedures, the fermenting substrates are substrates from the biogas reactor or from the post fermenter or final dump, and particularly the procedure is coupled with the pH measurement, in order to make remarks about the process stability.
