Biodegradation of a mixture of mononitrophenols in a packed-bed aerobic reactor
Popis výsledku v původním jazyce
Aerobic biodegradation of individual mononitrophenols (4-, 3- and 2-NPs) and their mixture in simulated wastewater was investigated in a packed-bed bench scale bioreactor continuously operated in a flow mode, with a mixed microbial culture adsorbed on expanded slate. Under a low, suboptimal hydraulic retention time (HRT) of 30min thereactor removed more than 3g.L1.day1 ofthe NP mixture while maintaining a > 8590% removal efficiency (RE). Under higher HRT values, starting at 45min, more than 2g.L1.day1 of the NP mixture were removed with an RE > 98%. Significant substrate interactions were observed; the addition of other NPs caused the saturation of 2-NP catabolic capacity whereas the addition of 2-NP caused the de-saturation of the 4- and 3-NP catabolic capacity. 3- and 4-NPs appeared to be removed independently, i.e., by different enzyme systems. After ten months ofoperation, thebiofilm composition was significantly altered to become predominantly bacterial. Only one originally inocul
