    Abstract Power-to-methane technology is a promising solution to facilitate the use of excess variable renewable energy for biomethane production. In this approach, hydrogen produced via electrolysis is used to upgrade raw biogas, which can be subsequently used as fuel or stored in the gas grid. Ex-situ biomethanation is an emerging technology that could potentially replace conventional energy-intensive biogas upgrading methods and allow CO₂ utilization for biomethane production. This work provides a comprehensive overview on the current status of ex-situ biomethanation with particular attention to trickle bed reactor. The review includes description of ex-situ biomethanation and summarizes previous works on this topic. The key elements related to operational conditions, efficiency, and microbiology of ex-situ biomethanation using trickle bed reactor are described here. Additionally, the review highlights the technical and economic issues that have to be addressed for future development and large-scale implementation of ex-situ biomethanation.

    Abstract Bicarbonate was evaluated as an alternative carbon source for a green microalga, Tetradesmus wisconsinensis, isolated from Lake Norsjø in Norway. Photosynthesis, growth, and lipid production were studied using four inorganic carbon regimes: (1) aeration only, (2) 20 mM NaHCO₃, (3) 5% (v/v) CO₂ gas, and (4) combination of 20 mM NaHCO₃ and 5% CO₂. Variable chlorophyll a fluorescence analysis revealed that the bicarbonate treatment supported effective photosynthesis, while the CO₂ treatment led to inefficient photosynthetic activity with a PSII maximum quantum yield as low as 0.31. Conversely, bicarbonate and CO₂ treatments gave similar biomass and fatty acid production. The maximum growth rate, the final cell dry weight, and total fatty acids under the bicarbonate-only treatment were 0.33 (± 0.06) day⁻¹, 673 (± 124) mg L⁻¹ and 75 (± 5) mg g⁻¹ dry biomass, respectively. The most abundant fatty acid components were α-linolenic acid and polyunsaturated fatty acids constituting 69% of the total fatty acids. The fatty acid profile eventuated in unsuitable biodiesel fuel properties such as high degree of unsaturation and low cetane number; however, it would be relevant for food and feed applications. We concluded that bicarbonate could give healthy growth and comparative product yields as CO₂.

    Abstract There are about ninety full-scale anaerobic digestion (AD) plants in South Korea that treat food waste (FW); however, the key diff ;erences in the microbial communities in different seasons and the effects of ammonia in AD remain poorly understood. In this study, the seasonal changes in microbial communities associated with operational parameters of two full-scale ADs (C and W plants) treating FW were analyzed. The organic loading rate (OLR) variability had an influence on the seasonal CH₄ yield; the W plant had a lower CH₄ yield with an unstable AD performance while the C plant had a higher CH₄ yield with a stable AD performance. It was mainly due to the substantially different NH₄⁺ concentration; the W plant had a NH₄⁺ concentration nearly 1.6 times higher compared to the C plant. The high NH₄⁺ presence in the W plant led to the dominance of class Clostridia, and methanogenesis was mostly done by hydrogenotrophs (Methanomassiliicoccus luminyensis). Additionally, the members belonging to Clostridia and Bacteroidia were found at both plants in each season (share ≥0.5%) implying their indispensable role during the anaerobic digestion of FW.

    Abstract This study showed that side stream voltage supplied by sludge recirculation from an auxiliary bio-electrochemical anaerobic digestion (ABEAD) reactor appears to have a similar effect as main stream voltage supply to an anaerobic digestion (AD) reactor. The increased sludge recirculation rate enhanced the operation stability at a high OLR. H2-producing bacterial community was improved in bio-electrochemical anaerobic digestion (BEAD) and ABEAD reactors and was increased with increase in sludge recirculation rate. Despite the dominance of hydrogenotrophic methanogens in all reactors, high operational performances of BEAD and ABEAD reactors supports the results of H2-producing bacteria increase in those reactors. The ABEAD reactors having 1/7 of the capacity of the main AD reactor showed possibility of integration of BEAD technology into new and existing facilities economically. The findings of this study would provide useful information for approaching the commercialization of BEAD and suggest direction of further research for practical applications.

  5. Article: Assessment of the relationship between solubilization and biogas production on anaerobic digestion of pretreated lipid-extracted microalgae waste

    Abstract It is commonly known that the pretreatment of complex substrates yields higher biogas production in anaerobic digestion (AD) by improving hydrolysis. However, it is still questioned whether all solubilized fractions after pretreatment can be used for CH₄ production during AD. In this study, the relationship between increased solubilization and AD efficiency in response to different pretreatment conditions of lipid-extracted microalgae waste (LEMW) was investigated. The individual pretreatment (acid and ultrasonic) and combined pretreatment were applied to assess the solubilization of LEMW. A biochemical methane potential (BMP) test was subsequently performed to determine the AD efficiency. Combined pretreatment of LEMW (60 min of irradiation + pH 1) showed the highest performance, achieving CH₄ production of 1245 ± 28 mL CH₄/L with increased solubilization of 50.4%. However, it was found that increased solubilization did not proportionally increase CH₄ productivity. The assessment of the origin of produced CH₄ through biomass fractionation supports this finding in that the soluble fraction that does not contribute to CH₄ production increased at more severe pretreatment conditions.

    Abstract The excessive H<inf>2</inf>S presence in water and wastewater can lead to corrosion, toxicity, and biological processes inhibition—i.e., anaerobic digestion. Production of H<inf>2</inf>S can occur in psychrophilic conditions. Biological removal of HS− by addition of NO<inf>3</inf>− as an electron acceptor under psychrophilic (10 °C) conditions in a continuous flow experiment is evaluated here. Four different N/S molar ratios—0.35, 0.40, 0.60, and 1.30—were tested in an expanded granular sludge bed (EGSB) reactor. Samples were analyzed daily by ion chromatography. Efficient psychrophilic HS− removal with sulfur products oxidation control by NO<inf>3</inf>− supply is documented. The highest HS− removal was obtained at N/S = 0.35 and 1.30 (89.1 ± 2.2 and 89.6 ± 2.9%). Removal of HS− was less at mid-N/S with the lowest value (76.9 ± 2.6%) at N/S = 0.60. NO<inf>3</inf>− removal remained high for all N/S ratios. N/S molar ratio influenced the sulfur products distribution with less S0 and increase in SO<inf>4</inf>2− effluent concentration with increasing N/S ratio. Oxidation of HS− and accumulated S0 occurred simultaneously at N/S ratios >0.35. The observations are explained by culture flexibility in utilizing available resources for energy gain.

    Abstract The simultaneous removal of NO3− and HS− at temperature stress (25–10°C) is evaluated here. An expanded granular sludge bed (EGSB) reactor was run over 120days at N/S molar ratio of 0.35 (for S0 production) under constant sulfur loading rate of 0.4kgS/m3d. The simultaneous removal of NO3− and HS−, was achieved at applied conditions. Average HS−-S removal varied from 98 (25°C) to 89.2% at 10°C, with almost complete NO3− removal. Average S0 yield ranged from 83.7 at 25°C to 67% at 10°C. The temperature drop caused a decrease in granular sludge accumulated S0 fraction by nearly 2.5 times. Decreased temperature caused metabolic pathway change observed as higher SO42− production, apparently allowing the biomass to obtain more energy per HS− consumed. It is hypothesized that the metabolic shift is a natural response to compensate for temperature-induced changes in energy requirements.
