Summary: The research found that reducing electrode spacing can improve power output and accelerate phenol biodegradation in bioelectrochemical systems (BESs). Additionally, the study revealed that the change in electric field intensity has a key impact on the performance of BESs, by selectively enriching phenol-degrading bacteria and inducing the secretion of extracellular polymeric substances to enhance degradation efficiency.

Summary: This article critically analyzes and discusses the latest development trends in Bioelectrochemical systems (BESs) for petroleum hydrocarbon (PH) bioremediation. The factors affecting the performance of BESs and their manipulations, such as reactor design, operational conditions, and microbial communities, are elaborated. The low mass diffusion condition in soil restricts the interaction between microbes and contaminants, thus further research is needed to optimize soil parameters and improve electrode design to make this technology more viable for field-scale applications.

Summary: Two-dimensional (2D)/2D g-C3N4/MoO3-x heterojunctions were constructed to enhance photocatalytic phenol removal. Oxygen vacancies in MoO3-x extended absorption in the full solar spectrum, especially in the near-infrared (NIR) region. Improved charge transfer path preserved photogenerated electrons and holes, resulting in enhanced phenol photodegradation performance and photocatalytic activation efficiency of peroxydisulfate (PDS). The presence of oxygen vacancies facilitated the formation of catalyst-PDS* complex, promoting the electron transfer process and exerting a crucial effect as a non-radical pathway.

Summary: This study evaluated the performance of microbial electrochemical treatment (MET) in terms of biodegradation and electricity generation for petroleum hydrocarbon-polluted soil by adding different doses of rice straw biochar. The results showed that increasing the dose of biochar led to a decrease in degradation of petroleum hydrocarbons and current density, as well as a change in bacterial community distribution. The redox-active quinone in biochar was identified as responsible for extracellular electron transfer.

Summary: Highly efficient phenol catalytic patterns were identified in Parageobacillus thermoglucosidasius W-36, which exhibited superior degradation performance compared to P. thermoglucosidasius W-2 with a single-pathway pattern. An exogenous degradation pathway was obtained through horizontal gene transfer, having distinct three-dimensional structures and substrate-binding sites from isofunctional enzymes. The dual-pathway pattern was time-dependently expressed in response to substrate levels, providing strain adaptability to high-concentration phenol. Evolutionary analysis suggested that the single/dual-pathway patterns may be a natural selection phenomenon caused by high-concentration phenol.

Summary: Hopanoid molecules are widely distributed in sedimentary rocks and play a significant role in the organic matter, oils, and bitumen found in these rocks. They are well preserved due to their stable chemical structure and are valuable as biomarkers or geomarkers. However, the early diagenetic processes of hopanoids are not fully understood, and their transformations with increasing thermal maturity have been shown to vary significantly. This study documents the changes in hopanoid compound classes with increasing thermal transformation and provides a detailed analysis of the different stages of transformation of these compounds.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.

Summary: This study investigated the impact of magnetite on the nitrogen cycle of pig manure biostabilisation. The addition of magnetite increased N2O emissions and decreased NH3 emissions during composting. It also increased the total nitrogen content but should be considered for its significant increase in N2O emissions in engineering practice.

Summary: This study investigated the operation of a 1000L microalgae-based membrane photobioreactor system for continuous secondary wastewater treatment. The research focused on a green microalgae strain called Desmodesmus sp. The study aimed to understand key trends and optimization strategies by conducting experiments in both summer and winter seasons. The findings showed that maintaining low cell concentrations during periods of light inhibition was beneficial for nutrient uptake rates. Effective strategies for enhancing algae-based wastewater treatment included cell mass recycling and adjusting dilution rates based on light availability.
