End-product inhibition and acidification limit biowaste fermentation efficiency

Removal of oxyfluorfen from polluted effluents by combined bio-electro processes

“…This allows to estimate the biomass growth rate, which initially follows an exponential trend regardless of the initial oxyfluorfen concentration. Thus, it can be concluded that the observed inhibition is due by the accumulation of poisoning degradation products (Probst et al, 2015). This was supported by the decreasing average biomass yield when the oxyfluorfen concentration increased, which decreased from 1.16 mg biomass mg -1 oxyfluorfen when operating at a concentration of oxyfluorfen under 150 mg L -1 to 0.71 and 0.66 mg mg -1 when operating at concentrations of 350 mg L -1 and 500 mg L -1 of oxyfluorfen, respectively.…”
