Summary: This study reports a newly isolated halotolerant strain Oceanisphaera arctica YHY1 capable of hydrolyzing seafood processing waste chitin biomass under high salt conditions, leading to stable electricity generation. By utilizing the by-products and metabolites from chitin degradation as electron donors, O. arctica YHY1 can generate electric current. Additionally, the involvement of outer membrane-bound cytochromes and extracellular redox mediators in the electron transfer mechanism was revealed through cyclic voltammetry investigation, FTIR, and XRD analysis of structural and functional group changes in chitin after degradation.

Summary: A photocathode-microbial electrochemical coupling system (PC-MFC) using black phosphorus-doped titanium dioxide nanobelt (BP/TB) as a photocatalyst was constructed to degrade hydroxychloroquine (HCQ, used to treat COVID-19). The degradation efficiency of HCQ (100 mg/L) in the coupling system reached 73.7% within 8 hours, higher than photocatalysis (69.5%), MFC (25.6%), and adsorption (9.6%). The PC-MFC achieved complete degradation of HCQ (100 mg/L) within 96 hours, significantly higher than the MFC (51.1%).

Summary: Microbial fuel cell (MFC) is a bio-electrochemical system that uses electrogenic bacteria to generate electricity. By utilizing wastewater as feed, MFC can generate clean electricity while treating the wastewater. However, there are challenges in scalability and commercialization of this technology, which can be overcome by the use of ceramics. Ceramics can provide chemical and structural stability as separators, chassis, or electrodes in MFCs, and they are low-cost, eco-friendly, and readily available.

Summary: In this study, breeding wastewater was efficiently treated using an electroactive microbial community screened from the native microorganisms of the wastewater in microbial fuel cells. The results showed good power generation and high pollutants removal efficiency. The morphology characterization demonstrated the formation of a thick biofilm by the screened electroactive microbial community. Microbial community analysis revealed an increase in microorganisms associated with electricity generation and pollutant degradation, while pathogenic microorganisms were greatly decreased. These findings suggest that the MFC constructed using the screened electroactive microbial community can be a sustainable method for breeding wastewater treatment.

Summary: This study investigated the performance of an ecological floating bed-microbial fuel cell (EFB-MFC) coupled system for electricity generation and nitrogen removal. Results showed that introducing plants into the MFC system reduced resistance and increased voltage, while also improving NH4+-N and TN removal efficiency. Water spinach system showed the best performance, but rotten roots of windmill grass released extra NH4+-N which impaired nitrogen removal. Radial oxygen loss and root exudates played significant roles in enhancing electricity generation and nitrogen removal. Electrical stimulation of enzyme activity related to nitrogen removal and migration of NH4+-N contributed to enhancing nitrogen removal.

Summary: The global market for fuel pellets is growing due to coal substitutes, but sustainability and biomass availability are major issues. Spent coffee grounds can be used to produce high heating value fuel pellets, but burning 100% SCG leads to high NO R emissions and low boiler efficiency. Mixing SCG with other biomass improves combustion performance. Further research is needed on the combustion and emissions of defatted spent coffee grounds.

Summary: The management of a large amount of food waste, equivalent to 1.3 billion tons, is a major challenge. Bread waste (BW) is a promising feedstock for biorefineries, and this review focuses on its potential for sustainable production of important chemicals. The availability of over 100 million tons of BW as a feedstock for biorefineries is discussed, along with examples of platform chemicals produced from BW, such as ethanol, lactic acid, succinic acid, and 2,3-butanediol. The review compares BW-based production of these metabolites with other feedstocks. It also addresses logistic and supply chain challenges associated with using BW as feedstock, and concludes with a discussion on life cycle analysis and comparison with other feedstocks.

Summary: In this study, fourteen types of biochar produced from seven different biomasses at 300 degrees C and 600 degrees C were tested for their ability to remove phenolics including furfural and hydroxymethylfurfural (HMF). Eucheuma spinosum biochar (EB-BC 600) showed the highest adsorption capacity for furfural (258.94 +/- 3.2 mg/g) and HMF (222.81 +/- 2.3 mg/g). Detoxified hydrolysates using EB-BC 600 biochar resulted in significantly increased production of polyhydroxyalkanoates (PHA).

Summary: Artificial intelligence (AI) and machine learning (ML) are currently being used in multiple domains, including the monitoring and design of biological wastewater treatment systems (WWTS). This paper reviews the available information on the applications of AI and ML models in WWTS, presenting bibliometric analyses, model descriptions, specific applications, and major findings. Predominantly used models in biological wastewater treatment include artificial neural networks (ANN), fuzzy logic (FL) algorithms, random forest (RF), and long short-term memory (LSTM), which are tested for predictive control of effluent parameters such as biological oxygen demand (BOD), chemical oxygen demand (COD), nutrient parameters, solids, and metallic substances. Commonly used model performance indicators for accuracy analysis include root mean squared error (RMSE), mean square error (MSE), and determination coefficient (DC). Additionally, this study summarizes the outcomes of various models.

Summary: Microbial exopolysaccharides (EPSs) such as xanthan, dextran, gellan, and curdlan have various applications in industries due to their biocompatibility, nontoxicity, and functional characteristics. However, their commercial use in healthcare practices is hindered by biodegradability issues, poor cell adhesion, mineralization, and low enzyme activity. Blending EPSs with other polymers can improve their characteristics and make the composites suitable for diverse applications, especially tissue engineering. More research is needed to address the challenges and commercialize these products.

Summary: In this study, N-methyl mesoporphyrin IX (NMM) was utilized as a voltammetric probe for the electrochemical detection of G4s. The detection of NMM was achieved by cyclic voltammetry on a hanging mercury drop electrode (HMDE) with a limit of detection (LOD) of 40 nM. The reduction signal of NMM was found to be significantly higher when G4 oligodeoxynucleotides (G4 ODNs) were present compared to single- or double-stranded ODNs or unfolded ODNs capable of forming G4s. Gradual transition from unstructured single strand to G4, induced by increasing concentrations of the G4 stabilizing K+ ions, was detected for the first time using electrochemical methods. Circular dichroism spectroscopy provided support for the obtained results. This work expands on the utilization of electrochemical probes for DNA secondary structure recognition and offers a proof of principle for the development of novel electroanalytical methods for nucleic acid structure studies.
