Microbial community and performance of slaughterhouse wastewater treatment filters


, : Microbial community and performance of slaughterhouse wastewater treatment filters. Genetics and Molecular Research 13(2): 4444-4455

The performance of anaerobic filter bioreactors (AFs) is influenced by the composition of the substrate, support medium, and the microbial species present in the sludge. In this study, the efficiency of a slaughterhouse effluent treatment using three AFs containing different support media was tested, and the microbial diversity was investigated by amplified ribosomal DNA restriction analysis and 16S rRNA gene sequencing. The physicochemical analysis of the AF systems tested suggested their feasibility, with rates of chemical oxygen demand removal of 72±8% in hydraulic retention times of 1 day. Analysis of pH, alkalinity, volatile acidity, total solids, total volatile solids, total Kjeldahl nitrogen, and the microbial community structures indicated high similarity among the three AFs. The composition of prokaryotic communities showed a prevalence of Proteobacteria (27.3%) and Bacteroidetes (18.4%) of the Bacteria domain and Methanomicrobiales (36.4%) and Methanosarcinales (35.3%) of the Archaea domain. Despite the high similarity of the microbial communities among the AFs, the reactor containing pieces of clay brick as a support medium presented the highest richness and diversity of bacterial and archaeal operational taxonomic units.
