“…These difficulties could be solved by selecting adequate operating conditions and scale-up criteria, which should be based on the microorganism metabolism, monitoring parameters in PCB such as O 2 consumption and CO 2 production. Both have been used to estimate the growth of the microorganism 11,12 and the heat generation 9,10 of the culture. Therefore, in this work, a respirometric analysis was carried out in cultures of M. robertsii; and kinetic parameters associated with O 2 consumption and CO 2 production were mathematically estimated.…”

“…Las tasas de consumo de O2 y de producción de CO2 se determinaron por el gradiente de concentración con respecto al contenido de cada gas en el aire alimentado al biorreactor, la masa de arroz seco inicial en el biorreactor y el flujo aire suministrado y, se expresó en mg/gmsi h. El consumo O2 y la producción de CO2 (en mg/gmsi) se estimaron evaluando el área bajo la curva de las tasas de O2 y CO2 con el método del trapecio (Griffiths and empleó el algoritmo no lineal de reducción generalizada del gradiente (GRG)(Lasdon et al, 1978). Para determinar el consumo global de O2 se utilizó el modelo de Soto-Cruz (2002) considerando al oxígeno como un sustrato (Ecuación 2)(Martínez-Ramírez et al, 2021). El rendimiento YCO2/O2 y el coeficiente de mantenimiento (mO2) se determinaron por regresión lineal.…”
