dc.description.abstract | The treatment of landfill leachate could be challenging for the biological wastewater
treatment systems due to its high toxicity and the presence of poorly biodegradable contaminants. In
this study, the bioaugmentation technology was successfully applied in sequencing batch reactors
(SBRs) fed with the phenolic landfill leachate by inoculation of the activated sludge (AS) with two
phenol-degrading Pseudomonas putida OR45a and Pseudomonas putida KB3 strains. According to the
results, the SBRs bioaugmented with Pseudomonas strains withstood the increasing concentrations of
the leachate. This resulted in the higher removal efficiency of the chemical oxygen demand (COD)
of 79–86%, ammonia nitrogen of 87–88% and phenolic compounds of 85–96% as compared to 45%,
64%, and 50% for the noninoculated SBR. Simultaneously, the bioaugmentation of the AS allowed
to maintain the high enzymatic activity of dehydrogenases, nonspecific esterases, and catalase in
this ecosystem, which contributed to the higher functional capacity of indigenous microorganisms
than in the noninoculated AS. Herein, the stress level experienced by the microorganisms in the
SBRs fed with the leachate computed based on the cellular ATP measurements showed that the
abundance of exogenous Pseudomonas strains in the bioreactors contributed to the reduction in effluent
toxicity, which was reflected by a decrease in the stress biomass index to 32–45% as compared to the
nonbioaugmented AS (76%). | pl_PL |
