“…MEC application for ammonium recovery looks particularly suitable if applied to 1-stage digestion plants that usually have a low conversion efficiency and work with a typical 30-day hydraulic retention time. Biomasses are considered costless for such systems, while major concerns are usually about nitrogen-induced methanogenic suppression (Ramm et al 2020) and slurry/digestate distribution cost. The readily degradable organic acids content in filtered digestate should be sufficient to sustain nitrogen recovery using MEC.…”

Growing food and biomass production at the global scale has determined a corresponding increase in the demand for and use of nutrients. In this study, the possibility of recovering nitrogen from agro-industrial digestate using bioelectrochemical systems was investigated: two microbial electrolysis cells (MECs) were fed with synthetic and real digestate (2.5 gNH 4 þ -N L À1 ). Carbon felt and granular graphite were used as anodes in MEC-1 and MEC-2, respectively. As to synthetic wastewater, the optimal nitrogen load (NL) for MEC-1 and -2 was 1.25 and 0.75 gNH 4 þ -N d À1 , respectively. MEC-1 showed better performance in terms of NH 4 þ -N removal efficiency (39 + 2.5%) and recovery rate (up to 70 gNH 4 þ -N m À2 d À1 ), compared to MEC-2 (33 + 4.7% and up to 30 gN m À2 d À1 , respectively). At the optimal hydraulic retention time, lower NH 4 þ -N removal efficiencies and recovery rates were observed when real digestate was fed to MEC-1 (29 + 6.6% and 60 + 13, respectively) and MEC-2 (21 + 7.9% and 10 + 3.6 gNH 4 þ -N m À2 d À1 , respectively), likely due to the higher complexity of the influent. The average energy requirements were 3.6-3.7 kWh kgN removed À1, comparable with values previously reported in the literature and lower than conventional ammonia recovery processes. Results are promising and may reduce the need for costly and polluting processes for nitrogen synthesis.

“…This could comprise components for pretreatment, for elimination of inhibiting substances, different reactor stages such as separate hydrolysis or ex-situ methanation for conversion of gases, treatment of digestate and the processing or upgrading of produced biogas. Some of these parts can be easily included as modular components in biogas plants (e.g., pretreatment or digestate treatment modules [169]), others are still under investigation or need to be developed (e.g., modules for removal of process inhibitors, such as ammonia stripping or magnesium ammonium phosphate precipitation [170]). Activation of modular components on demand requires feedstock and process surveillance and reliable control systems.…”

After nearly two decades of subsidized and energy crop-oriented development, agricultural biogas production in Germany is standing at a crossroads. Fundamental challenges need to be met. In this article we sketch a vision of a future agricultural biogas plant that is an integral part of the circular bioeconomy and works mainly on the base of residues. It is flexible with regard to feedstocks, digester operation, microbial communities and biogas output. It is modular in design and its operation is knowledge-based, information-driven and largely automated. It will be competitive with fossil energies and other renewable energies, profitable for farmers and plant operators and favorable for the national economy. In this paper we discuss the required contribution of research to achieve these aims.

“…Although the sequencing was not carried out in situ , the suitability of MinION for monitoring and evaluating an industrial process through a microbial marker was demonstrated. Bacteriomes involved in the biogas production have been also studied through nanopore sequencing [ 54 , 55 ], producing results which could be coupled with the Lotka–Volterra model for analysing the microbial interactions occurring in the reactor [ 56 ].…”

High-throughput metagenomic sequencing is considered one of the main technologies fostering the development of microbial ecology. Widely-used second generation sequencers have enabled the analysis of extremely diverse microbial communities, the discovery of novel gene functions, and the comprehension of the metabolic interconnections established among microbial consortia. However, the high cost of the sequencers and the complexity of library preparation and sequencing protocols still hamper the application of metagenomic sequencing in a vast range of real-life applications. In this context, the emergence of portable, third-generation sequencers is becoming a popular alternative for the rapid analysis of microbial communities in particular scenarios, due to their low cost, simplicity of operation, and rapid yield of results. This review discusses the main applications of real-time, in situ metagenomic sequencing developed to date, highlighting the relevance of this technology in current challenges (such as the management of global pathogen outbreaks) and in the next future of industry and clinical diagnosis.
