“…It was known for its fermentative activity, producing acetate, malate, propionate, formate, and H 2 . The Dysgonomonadaceae contained three dominant genera, Fermentimonas, Petrimonas, and Proteiniphilum, all known for fermentative activities producing acetate [50,51]. The Synergistaceae family (which predominated in anolyte samples) was also involved in the acetogenesis [52].…”

Microbial electrochemical technologies now enable microbial electrosynthesis (MES) of organic compounds using microbial electrolysis cells handling waste organic materials. An electrolytic cell with an MES cathode may generate soluble organic molecules at a higher market price than biomethane, thereby satisfying both economic and environmental goals. However, the long-term viability of bioanode activity might become a major concern. In this work, a 15-L MES reactor was designed with specific electrode configurations. An electrochemical model was established to assess the feasibility and possible performance of the design, considering the aging of the bioanode. The reactor was then constructed and tested for performance as well as a bioanode regeneration assay. Biowaste from an industrial deconditioning platform was used as a substrate for bioanode. The chemical oxygen demand (COD) removal rate in the anodic chamber reached 0.83 g day−1 L−1 of anolyte. Acetate was produced with a rate of 0.53 g day−1 L−1 of catholyte, reaching a maximum concentration of 8.3 g L−1. A potential difference (from 0.6 to 1.2 V) was applied between the bioanode and biocathode independent of reference electrodes. The active biocathode was dominated by members of the genus Pseudomonas, rarely reported so far for MES activity.

Electrode modification is crucial in improving the power density and bioelectrochemical performance of a microbial fuel cell (MFC). The conventional carbon felt (CF) surface was modified as an anode in this study to examine an emerging class of materials known as covalent organic framework (COF). In a three-electrode system, the performance of the modified anode (TpPa-1@CF) was evaluated using various physical and bioelectrochemical techniques, demonstrating superior bioelectrochemical activity (cyclic voltammetry), reduced electrode resistance (electrochemical spectroscopy), and excellent electrode stability (chronoamperometry). With a 4.3 and 12.7-fold improvement in power (1069 mW/m 2 ) and current (1954 mA/m 2 ) density and steady MFC performance as compared to the uncoated electrode throughout five MFC cycles, TpPa-1@CF demonstrated better bioelectrochemical activity. Furthermore, the rough electrode surface area and numerous catalytically active sites of TpPa-1@CF promoted the microbial growth/adhesion along with substrate fluxes yielding the selective enrichment of Proteobacteria and Bacteroidetes (electricity-producing phyla). These results indicated that TpPa-1@CF is a promising anode material for several bioelectrochemical applications.

“…They can cause teratogenesis, cancer, and death [ 4 , 5 ]. Traditional treatment methods, such as chemical precipitation [ 6 ], electrocatalysis [ 7 ], and microbial degradation [ 8 ], struggle to completely remove these impurities. Electrocatalysis, for example, can be costly due to using more expensive metals as electrodes [ 7 ].…”

“…The chemical precipitation method causes serious secondary pollution due to its use of a large number of flocculants [ 6 ]. Although the microbial method has low energy consumption and is sustainable, the treatment cycle is longer than for other methods [ 8 ]. Therefore, there is an urgent need to develop more efficient and green methods to quickly remove organic pollutants.…”

Luffa leaf (LL) is an agricultural waste produced by loofah. In this work, LL was used as biomass carbon source for biochars for the first time. After carbonization, activation, and chemical co-precipitation treatments, a magnetic lignocellulose-derived hierarchical porous biochar was obtained. The specific surface area and total pore volume were 2565.4 m2/g and 1.4643 cm3/g, and the surface was rich in carbon and oxygen functional groups. The synthetic dye rhodamine B (RhB) and the antibiotic tetracycline hydrochloride (TH) were selected as organic pollutant models to explore the ability to remove organic pollutants, and the results showed good adsorption performances. The maximum adsorption capacities were 1701.7 mg/g for RhB and 1755.9 mg/g for TH, which were higher than most carbon-based adsorbents. After 10 cycles of use, the removal efficiencies were still maintained at more than 70%, showing good stability. This work not only verified the feasibility of lignocellulose LL as a carbon source to prepare biochar but also prepared a magnetic hierarchical porous adsorbent with good performances that can better treat RhB and TH, which provided a new idea and direction for the efficient removal of organic pollutants in water.
