Kinetic and stoichiometric characterization of a fixed biofilm reactor by pulse...
Ordaz, Alberto; Oliveira, Catarina S.; Quijano, Guilhermo; Ferreira, E. C.; Alves, M. M.; Thalasso, FrédéricAn in situ respirometric technique was applied to a sequential biofilm batch reactor treating a synthetic wastewater containing acetate. In this reactor, inoculated with mixed liquor from a wastewater plant, unglazed ceramic tiles were used as support media while maintaining complete mixing regime. A total of 8 kinetic and stoichiometric parameters were determined by pulse respirometry, namely substrate oxidati...
In situ pulse respirometric methods for the estimation of kinetic and stoichiom...
Oliveira, Catarina S.; Ordaz, Alberto; Ferreira, E. C.; Alves, M. M.; Thalasso, FrédéricIn situ pulse respirometry was applied in an activated sludge bubble column treating synthetic wastewater for the estimation of the (i) maximum specific oxygen consumption rate, (ii) substrate affinity constant, (iii) biomass growth yield, (iv) maintenance coefficient, and (v) specific endogenous respiration rate. Parameters obtained through respirometry were compared to those obtained by the chemostat method, ...

Determination of kinetic and stoichiometric parameters of pseudomonas putida F1...
Oliveira, Catarina S.; Ordaz, Alberto; Alba, Joel; Alves, M. M.; Ferreira, E. C.; Thalasso, FrédéricThe applicability of pulse respirometry, for the estimation of kinetic and stoichiometric parameters in pure cultures was evaluated by comparison with traditional chemostat method. Pseudomonas putida F1 was cultured in a continuous stirred tank reactor, using glucose as sole carbon source. The reactor was operated under steady-state with six dilution rates, ranging from 0.06 to 0.35 h-1. Substrate and biomass c...
Kinetic and stoichiometric parameters estimation in a nitrifying bubble column ...
Ordaz, Alberto; Oliveira, Catarina S.; Aguilar, Ricardo; Carrión, Manuel; Ferreira, E. C.; Alves, M. M.; Thalasso, FrédéricThis article proposes a simple "in-situ" pulse respirometric method for the estimation of four important kinetic and stoichiometric parameters. The method is validated in a suspended biomass nitrifying reactor for the determination of (i) maximum oxygen uptake rate (OURexmax), (ii) oxidation yield (fE), (iii) biomass growth yield (fS), and (iv) affinity constant (KS). OURexmax and fE were directly obtained from...
