Summary: A halo-thermophilic bacterial consortium capable of decolorizing azo dye under high salinity and temperature conditions was enriched in this study, with Bacillus identified as the dominant genus playing a key role in the decolorization process. The consortium demonstrated effectiveness in decolorization of metanil yellow G across a wide range of pH values, temperatures, dye concentrations, and salinities. Additionally, various enzymes such as laccase, manganese peroxidase, lignin peroxidase, and azoreductase were found to be involved in the decolorization process, with a proposed pathway for decolorization based on GC-MS and FTIR results.

Summary: Mycoremediation of textile effluents, such as synthetic dyes, is an effective and eco-friendly method. Dyes discharged from industries like textile, food processing, chemical, leather, dyestuff, dyeing, and pharmaceutical can negatively impact the natural ecosystem. Lentinus squarrosulus AF5, a strain of fungus, has been identified as a potential decomposer of these dyes. Proteomic analysis revealed differential protein expression in the strain when exposed to the dyes, indicating the important role of extracellular peroxidases in the decolorization process. UV-Visible, FTIR spectroscopic, HPLC, and LC-QTOF-MS analyses confirmed the degradation of the dyes by Lentinus squarrosulus AF5.

Summary: This study isolated and identified a bacterial strain with the potential to decolorize and degrade Reactive Black 5 (RB5). The strain, identified as Bacillus albus DD1, showed a 98% removal of RB5 within 38 hours under optimum conditions. Kinetic and thermodynamic analyses revealed that the decolorization reaction was a first order non-spontaneous reaction, and the degradation of RB5 occurred through the cleavage of the azo bond.

Summary: In this study, nitrogen-doped graphene (NG) was found to significantly accelerate the decolorization of methyl orange (MO) azo dye by sulfide. The stagnant time of MO decolorization was remarkably reduced in the presence of NGs, particularly those with graphitic nitrogen. Doping nitrogen improved the electron conductivity and enhanced the interactions between sulfide and carbon atoms bonded to graphitic nitrogen, leading to the formation of reactive intermediate polysulfides.

Summary: Considering the increasing health concerns, urban population tends to adopt a healthy lifestyle and incorporate nutritional food supplements to mitigate common health risks. The consumption of omega-3 and omega-6 PUFAs is on the rise, thus alternative commercial production methods are being developed. Microbial sources are emerging platforms to meet the global demand for omega PUFAs. Marine oleaginous protist Aurantiochytrium sp. has been identified as a potential source for substantial production of DHA and SFA. The objective of this research was to enhance PUFA yield by optimizing glucose concentration and nitrogen ratio. The maximum lipid and DHA yield and content were achieved at 30 g/L glucose, while the relative PUFA content was highest at 10 g/L glucose, with remaining SFA potentially usable for biodiesel.

Summary: A sequential anaerobic digestion and phycoremediation process was used to recover nutrients and remove pollutants from dairy wastewater while producing biomethane and biochemicals. The anaerobic digestion achieved a methane content of 53.7% and production rate of 0.17 L/L/d, along with significant removals of chemical oxygen demand, total solids, and volatile fatty acids. The digestate was then used to grow Chlorella sorokiniana SU-1, resulting in high removal efficiencies of total nitrogen, total phosphorus, and COD. The microalgal biomass obtained was co-digested with dairy wastewater, leading to improved methane production performance.

Summary: This study explores the simultaneous removal of sulfamethoxazole (SMX) and production of short-chain fatty acids (SCFAs) by a microbial consortium dominated by Clostridium sensu stricto. The process involved anaerobic co-metabolism, resulting in the production of butyric acid, valeric acid, succinic acid, and caproic acid. Continuous cultivation achieved high SMX degradation rates and reduced the prevalence of antibiotic-resistant genes, providing a promising approach for efficient antibiotic elimination while generating valuable products (SCFAs).

Summary: Plastics have become an essential part of life, but when they enter the environment, they break down into smaller fragments called microplastics (MPs) which are detrimental to the environment and human health. Bioremediation is considered the most environmentally friendly and cost-effective method for MP degradation, but there is limited knowledge about it. This review explores the sources and migration behavior of MPs, discusses biodegradation potential and mechanisms, analyzes the factors influencing biodegradation, and discusses the prospects and challenges of biodegradation technologies for MPs.

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.
