Abstract

An apparatus and method for anaerobic and aerobic respirometry. The apparatus and method provide for automatically collecting and analyzing the data required to calibrate mathematical models for bioprocesses that involve anaerobic respiration, aerobic respiration and dehalogenation. Dissolved electron-acceptor concentrations and/or product concentrations and/or headspace pressures are automatically monitored during the progress of a biotransformation occurring in a batch reactor to produce a data set. The data set is analyzed to derive intrinsic kinetic parameters and stoichiometric coefficients. The cultures biocatalyzing the oxidation-reduction reactions of interest may be aerobic, denitrifying (e.g., nitrate-reducing), sulfate reducing and/or methanogenic. The models thus developed may be used for design of wastewater treatment or bioremediation processes.
