The effects of phenol on the nitrogen removal performance a sequencing batch reactor (SBR) with anammox activity and microbial community within were evaluated. A concentration 300 mg L−1 reduced ammonium–nitrogen efficiency SBR from 96.5% to 47%. addition changed structure composition considerably, as shown by denaturing gradient gel electrophoresis 454 pyrosequencing 16S rRNA genes. Some phyla, such Proteobacteria, Verrucomicrobia, Firmicutes, increased in abundance, whereas others,...
The effects of temperature reduction (from 35 °C to 20 °C) on nitrogen removal performance and microbial diversity an anammox sequencing batch reactor were evaluated. was fed for 148 days with anaerobically pretreated municipal wastewater amended nitrite. On average, efficiencies ammonium nitrite high (96%) during the enrichment period phases 1 (at 2 25 °C), slightly decreased (to 90%) when operated at °C. Deep analysis revealed that community structure changed decrease. Anammox bacteria...
The microbial community structure of the biomass selected in two distinctly inoculated anaerobic oxidation ammonium (anammox) reactors was investigated and compared with help data obtained from 454-pyrosequencing analyses. anammox were operated for 550 days seeded different sludges: sediment a constructed wetland (reactor I) an aerated lagoon part oil-refinery wastewater treatment plant II). diversity inocula evaluated by 16S rRNA gene-cloning analysis. bacteria greater sludge (three five...
Sewage surveillance can be used as an effective complementary tool for detecting pathogens in local communities, providing insights into emerging threats and aiding the monitoring of outbreaks. In this study using qPCR whole genomic sewage surveillance, we detected Mpox virus along with other viruses, municipal hospital wastewaters Belo Horizonte, Brazil over a 9-month period (from July 2022 until March 2023). MPXV DNA detection rates varied our study, 19.6% (11 out 56 samples) through...
Alkaline treatment is widely used to reduce pathogens in sewage sludge developing countries and guarantee that it safe for use agriculture. The aim of this study was investigate the effect alkaline applied waste-activated (WAS) Upflow Anaerobic Sludge Blanket (UASB)-sludge on bacterial community, (viable helminths eggs Salmonella spp), antibiotic resistance genes (ARG). community structure examined through denaturing gel gradient electrophoresis (DGGE), targeting 16S rRNA genes. Polymerase...

RESUMO Estações de tratamento esgotos (ETEs) estão entre as principais fontes disseminação bactérias resistentes a antibióticos (BRAs) e genes resistência (GRAs) no ambiente. Este trabalho quantificou ocorrência aos ampicilina cloranfenicol esgoto bruto (EB), efluente tratado (ET) lodo duas ETEs em escala plena por um período nove meses. As unidades investigadas utilizavam os seguintes sistemas tratamento: ETE-A, sistema lodos ativados convencional; ETE-B, reatores anaeróbios (UASB) seguidos...
Abstract Two bioreactors were investigated as an alternative to post-treatment of effluent from upflow anaerobic sludge blanket (UASB) reactor treating domestic sewage, with aim oxidizing sulfide into elemental sulfur, and removal solid organic material. The operated at different hydraulic retention times (HRTs) (6, 4, 2 h) in the presence or absence (control) packing material (polypropylene rings). Greater efficiencies – 75% (control reactor) 92% (packed achieved both reactors for HRT 6 h....
RESUMO A recente detecção de material genético (RNA) do novo coronavírus em amostras fezes e no esgoto aponta para a possibilidade se identificar circulação vírus até mesmo estimar o número pessoas infectadas determinada região pelo monitoramento sistemático esgoto, configurando-se importante ferramenta epidemiológica testagem massiva indireta, incluindo portadores sintomáticos assintomáticos. Nesse sentido, concebeu-se um projeto quantificação coletadas 15 sub-bacias esgotamento sanitário...
