Summary: This study investigates the impact of biochar derived from sewage sludge on the efficiency of anaerobic granular digestion. The presence of biochar does not affect methane production from established anaerobic granules, but it accelerates electron transfer and inhibits methane production by influencing free anaerobic microorganisms in the solution.

Summary: In this study, the effects of long-term bioreactor (un)stability on resistance to shock loads were evaluated. The results showed that the reactor with stable operation performed better in terms of resistance to a sudden increase in organic loading rate, despite having lower microbial community diversity. The operation history of a reactor plays a crucial role in determining its ability to withstand environmental perturbations.

Summary: In this study, the dynamics of microbial and viral communities in an expanded granular sludge bed (EGSB) reactor were investigated. The results showed that COD, VSS/TSS ratio, and temperature were the main factors affecting the microbial community structure. The study also identified key genes involved in nitrogen cycling, with the dissimilatory nitrate reduction to ammonia (DNRA) and denitrification pathways dominating in the anaerobic system. The findings provide insights for the optimization of engineered systems.

Summary: This study successfully treated poultry slaughterhouse wastewater (PSW) by combining a biological pretreatment stage, an expanded granular sludge bed reactor (EGSB), and a membrane bioreactor (MBR). The system achieved contaminant removal rates exceeding 97%, meeting the discharge standards set by the City of Cape Town (CoCT). The EGSB and MBR played key roles in reducing concentrations of total suspended solids (TSS), chemical oxygen demand (COD), and fats, oil, and grease (FOG) to acceptable levels, demonstrating an effective and low-cost method for treating medium- to high-strength wastewater.

Summary: Anaerobic co-digestion can improve the yields and stability of single anaerobic digestion, but finding the right substrate proportions and optimal operating conditions is a challenge. This research used three EGSB reactors to study the anaerobic digestion of three mixtures from piglet manure, cow manure, starch wastewater, and sugar beet. It was found that three-substrate mixtures can achieve predicted synergistic effects and have stability.

The granule size had a positive effect on the removal of specific organics in wastewater, but a negative effect on ammonium and phosphorus removal. Granule size can be used as an indicator to reflect the synergistic interactions between microalgae and bacteria in microalgal-bacterial granules.

Summary: Microplastics and nanoplastics released into wastewater may threaten the biological treatment process. Aerobic granular sludge (AGS), a potential biotechnology for wastewater treatment, can effectively intercept microplastics and nanoplastics, but their effects on the AGS system have been insufficiently investigated. This study found that low concentrations of microplastics and nanoplastics (1 mg/L) had negligible inhibitory effects on the AGS system. However, higher concentrations of microplastics (20 and 100 mg/L) impaired granular integrity and reduced total nitrogen removal efficiency by 3.8%-17.8%, particularly in denitrification. Prolonged exposure to nanoplastics at the same concentrations had greater adverse effects on AGS, indicated by filamentous bacteria overgrowth and lower TN removal efficiency (decreased by 11.4%-22.8%). This is possibly due to biofilm formation on the surface of microplastics and excessive secretion of extracellular polymeric substances that mitigate the toxic effects of microplastics. In contrast, microorganisms were directly exposed to the toxicity of nanoplastics, resulting in increased oxidative stress, impaired cytomembrane structure, decreased cell viability, and protein production. Metagenomic analysis revealed decreased populations of key functional bacteria (e.g. denitrifiers Acidovorax and Flavobacterium) and declined key enzymes and genes (e.g. nirK, napAB, nirS, norBC, and nosZ) related to nitrogen transformation processes and energy production. This study suggests that nanoplastics have more detrimental impacts on AGS systems, which should be taken into account when treating plastic-containing wastewaters.

Summary: Removing sulfate prior to methanogenesis and maintaining year-round operation are the main challenges for highly efficient bioenergy recovery from sugarcane vinasse. The study assessed the establishment and optimization of sulfidogenesis during vinasse fermentation at different temperature levels and the impact of replacing vinasse by molasses. The results showed that sulfidogenesis was not efficiently established at 30 degrees C, but successful sulfate removal was achieved at 55 degrees C. Replacing vinasse by molasses negatively impacted sulfate-reducing bacteria but they were resilient to severe acidic and thermophilic conditions.

Summary: The feasibility of simultaneous removal of indium, selenite, and tellurite using bio-reduction by Aspergillus niger fungal pellets was investigated. The study found that A. niger pellets demonstrated good removal capabilities for indium, selenium, and tellurium in different combinations. The fungal biomass showed accumulation of elemental selenium and tellurium nanoparticles within the pellets. This research suggests that fungal pelleted systems can effectively recover elemental chalcogens and indium chalcogenide nanoparticles.

Summary: A sustainable biorefining and bioprocessing strategy was developed to produce edible-ulvan films and non-edible polyhydroxybutyrate films. Edible-ulvan films were prepared by crosslinking and plasticisation of ulvan with citric acid and xylitol, improving gut-friendly microbe growth and inhibiting pathogens. Biomass from green macroalgae was processed to produce volatile fatty acids, which were further converted into polyhydroxybutyrate through aerobic processing.

Summary: Stressosomes are signal-sensing and integration hubs identified in many bacteria, and this study provides the first in vivo characterization of the stressosome in a Gram-negative bacterium, Vibrio vulnificus. The stressosome is likely involved in reshaping glucose metabolism under iron and nutrient-limited conditions, affecting the activation of the glyoxylate shunt. Additionally, the stressosome is necessary for the transcription of fleQ and promotes motility, suggesting it plays a role in regulating c-di-GMP.

Summary: A comparative study was conducted to investigate the effects of various parameters on power generation in an aerobic microbial fuel cell using cow manure-pretreated slurry and sewage sludge. The optimal conditions for maximum power production were determined to be an electrode depth of 7 cm, a pH of 6, and a feed ratio of 2:1 in the CM + SS system. Response surface methodology was applied to establish the relationship between the parameters and the response. The results showed that an ON/OFF controller was effective in maintaining stable power output.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.

Summary: Atmospheric PM2.5, which can generate reactive oxygen species (ROS), is associated with cardiorespiratory morbidity and mortality. The study found that both the mass concentration of PM2.5 and the DTT activity were higher during the heating season than during the nonheating season. Combustion sources were the primary contributors to DTT activity during the heating season, while secondary formation dominated during the nonheating season. The study also revealed that biomass burning had the highest inherent oxidation potential among all sources investigated.

Aluminum was found in tumor areas of 24% of patients and was associated with epithelial to mesenchymal transition (EMT) and cell death. Additional analyses revealed higher tumor mutational burden and mutations in genes related to EMT and apoptosis in aluminum-positive colon cancers. Understanding the molecular mechanisms of aluminum toxicity may improve strategies for the management of colon cancer patients.
