“…Petropoulos et al [ 59 ] compared the performances of two UASB reactors operating in an extreme condition of low temperature (4 °C), with and without an ultrafiltration membrane. They pointed out two interesting aspects: (i) organic substance conversion into methane occurred also in this condition with an HRT equals to 3 days, and (ii) both systems produced comparable results proving that degradation efficiency was not affected by the coupling with an ultrafiltration membrane [ 59 ].…”

The interest in research on up-flow anaerobic sludge blanket (UASB) reactors is growing. The meta-analysis of bibliometric data highlighted the growing interest in four diverse topics: (i) energy recovery production; (ii) combination with other treatments; (iii) the study of processes for the removal of specific pollutants and, (iv) characterization of microbial community and granular sludge composition. In particular, the papers published in the first 6 months of 2021 on this process were selected and critically reviewed to highlight and discuss the results, the gaps in the literature and possible ideas for future research. Although the state of research on UASB is to be considered advanced, there are still several points that will be developed in future research such as the consolidation of the results obtained on a semi-industrial or real scale, the use of real matrices instead of synthetic ones and a more in-depth study of the effect of substances such as antibiotics on the microbiota and microbiome of UASB granular biomass. To date, few and conflicting data about the environmental footprint of UASB are available and therefore other studies on this topic are strongly suggested.

“…The feed was introduced into the reactors either as Sterile (treated with ultraviolet light to exclude mesophilic biomass of the feed) or Non-sterile. The psychrophilic biomass was acclimated to both the operating temperatures (4 and 15 • C) and feed types as described by Petropoulos et al (2017Petropoulos et al ( , 2019Petropoulos et al ( , 2021 through series of batch and continuous experiments which lasted for more than three years. In this study, we re-acclimated the reactors for two months (hydraulic retention time was 60 h) and sampled (from both the bulk liquid and biofilm formed on the membrane) on Day 65 when the reactors were working at the steady state at the above-mentioned operational conditions.…”

“…Selection of PCR primers, such as F515/R806 (Caporaso et al, 2011) target the methanogenic Archaea that dominate in anaerobic digesters while simultaneously targeting bacterial groups common in anaerobic digestion. However this primer set preferentially targets Archaea in phyla associated with methanogenesis while missing many other archaeal phyla (Petropoulos et al, 2021) that are detected by Archaea-specific primers such as 349F/806R (Bahram et al, 2019). Use of Archaea-specific primers have been reported to detect Bathyarchaeota and other Archaeal phylum in anaerobic digesters (Lam et al, 2020).…”

Family-scale rural digesters are widely implemented in Nepal for waste management, resource recovery, and environmental stewardship for distributed communities. However, there is little documentation on the microbial community structures in real-world family farm digesters. This work compared microbial community structures in four family digesters to a near-by municipal digester. Included in the family digesters was a high-altitude family digester located on Mt. Everest in Mosi, Nepal (2,634 m elevation).Differences in the community structures included the prevalence in family digesters of Bathyarchaeota MGC-6. MCG-6 is an archaeal population putatively involved in autotrophic acetate generation and conversion of cellulose to sugars. Additionally, Rikenellaceae DMER64, a population thought to degrade sugars, was more prevalent in the family digesters. The ratio of Methanothrix to hydrogenotrophic methanogens was higher in the family digesters. Additionally, the dominant species of syntrophic hydrogen-producing bacteria differed. Syntrophobacter and Syntrophomonas species, documented for their critical roles in waste activated sludge digesters, were not detected. In conclusion, observed differences in microbial community composition suggested a capacity to support different substrate conversion pathways and a major role of Archaea beyond methanogenesis among the studied digesters.

Sewage treatment at 4 °C in anaerobic upflow reactors with and without a membrane – performance, function and microbial diversity

Abstract: In this study, we investigated the feasibility of anaerobic sewage treatment at extremely low temperatures (4 °C) using two reactor setups: Upflow anaerobic sludge blanket reactors (UASB) without and with (AnMBRUASB(UF)) a membrane.
