Pollutant interactions during the biodegradation of phenolic mixtures with either 2- or 3-mononitrophenol in a continuously operated packed bed reactor

Popis výsledku v původním jazyce

Pollutant interactions during the aerobic biodegradation of phenolic mixtures with either 2-nitrophenol (2-NP) or 3-nitrophenol (3-NP) by a NP-adapted microbial consortium in simulated wastewater were studied in a packed-bed bench scale bioreactor continuously operated in a flow mode. Phenol/2-NP and phenol/3-NP mixtures with varied phenol/nitrophenol ratios were shown to exhibit different biodegradability patterns. The presence of 2-NP led to a much lower overall elimination capacity and lower processstability in comparison to mixtures with 3-NP. In contrast to the expected greater degradation of a more biodegradable substrate in mixtures, phenol was degraded with a lower efficiency at higher phenol concentrations than NPs, although this difference became less pronounced with the gradual biofilm adaptation to phenol. This unusual substrate interaction, which appears to be common in the biotreatment of substituted phenol mixtures, was explained by prior biofilm adaptation to less degr
