Summary: A wastewater treatment system utilizing sulfate-reducing and sulfide-oxidizing processes was developed for organic wastewater with high sulfate/sulfide content. The study investigated the impacts of COD/SO42- ratio and hydraulic retention time (HRT) on the removal efficiencies of sulfate, COD, sulfide, and electricity generation. The results showed stable COD and sulfate removal efficiencies of 94.8±0.6% and 93.0±1.3% during the 63-day continuous operation. A power density level of 18.0±1.6 mW/m2 was achieved with a sulfide removal efficiency of 93.0±1.2%. However, sulfide removal efficiency and power density gradually decreased after 45 days, potentially due to sulfur accumulation on the anode.

Summary: This study demonstrated the different solubility of nickel and cobalt in the presence of sulfate reducing bacteria, with nickel remaining soluble while cobalt often precipitated as sulfide. Proteins identified in the experiments were found to play various roles in maintaining nickel homeostasis, functioning as metalloenzymes, and containing nickel-binding ligands. Specific species like Desulfomicrobium baculatum, Stenotrophomonas maltophilia, and Desulfovibrio magneticus were responsible for producing these proteins.

Summary: In this study, a mathematical model considering multiple pathways of glycerol fermentation combined with sulfate reduction was established and verified. It was found that glycerol fermentation mainly went through oxidative and reductive pathways, producing ethanol and 1,3-propanediol. 1,3-propanediol was converted to 3-hydroxypropionate coupled with sulfate reduction, and 3-hydroxypropionate was further oxidized to acetate.

Summary: The study investigated the microbiologically influenced corrosion (MIC) of zinc and galvanized steel caused by sulfate reducing bacteria (SRB). Despite a slightly higher sessile cell count, galvanized steel showed less susceptibility to SRB MIC compared to pure zinc. The corrosion product for both metals was mainly ZnS, with three possible MIC mechanisms identified.

Summary: This study aimed to enhance sulfidogenic activity through SRB enrichment and minimize organic carbon loss by inhibiting methanogen activity. The dominant SRB in the sulfidogenic stage were found to be Desulfovibrio, Desulfotomaculum, and Syntrophobacter. Economic feasibility analysis showed that the TSADS could reduce the cost of CH4 production compared to single-stage anaerobic digestion.

Summary: Sulfate-reducing bioreactors were used to treat acid mine drainage in this study. Two separate bioreactors with pH and temperature control were operated using different acidophilic microbial consortia to remove sulfate from synthetic acidic mine water. Both bioreactors showed similar performance in sulfate removal and contained Desulfosporosinus as the main sulfate-reducing bacteria.

Summary: In this study, culturable sulfate-reducing bacteria (SRB) were isolated and identified from the inner rust layer of steel and sediments. A comparison of amino acid sequences encoding related enzymes in the sulfate reduction pathway was conducted between anaerobic and facultative anaerobic SRB strains. The study found differences in the distribution of enzymes between the two types of SRB, providing insights into the metabolic mechanisms and potential applications of SRB.

Summary: Phosphogypsum (PG) generated during phosphoric acid production contains a significant amount of sulfate, which can be biologically converted into sulfide. This study focuses on selecting and evaluating microbial consortia from sulfate-rich environments for the initial step of sulfur recovery. The MYC-consortium isolated from a hydrothermal niche showed the highest reduction capacity and performance under various conditions. This research provides insights into the potential of the MYC-consortium in converting sulfate from PG into sulfide, which is a critical step in sulfur biorecovery.

Summary: The application of sulfate reducing bacteria (SRB) has been found to efficiently convert sulfate to sulfide and precipitate transition metals as sulfides. In this study, SRB was used to produce hydrogen sulfide, which was then used to synthesize copper sulfide nanoparticles. The physico-chemical properties of the nanoparticles were analyzed, and their photocatalytic activities for organic dye removal were evaluated. It was discovered that the properties of the nanoparticles can be controlled by adjusting the copper concentration during synthesis. The results show the potential of using dissimilatory reduction of sulfate mediated by SRB to obtain valuable copper sulfide nanoparticles.

Summary: Bacteria generate and release extracellular reactive oxygen species (eROS), which significantly contribute to the natural ROS pool and play a crucial role in metabolic interactions of bacteria with their environment. Understanding the behavior of eROS-generating bacteria and its environmental implications is of great importance in the cycling of biogeochemical elements, transformation of organic matter, and regulation of antibiotic resistance genes.

Summary: Plastics and microplastics are widely present and accumulating in the environment, leading to increasing public attention. In addition to packaging plastics, materials from industries such as electronics, space and aviation are also accumulating, but receiving less attention. The production of degradable and biodegradable plastics is seen as a way to reduce environmental impacts, but enhancing the non-degradability of functional polymers is also a feasible option. Microbial colonization and deterioration pose significant challenges to these materials.

Summary: This study evaluated the keratinolytic activity of 37 strains of Trichophyton ajelloi and found that pigmented strains isolated from loamy soil were more efficient in degrading native feather keratin, while non-pigmented strains isolated from chernozem showed better abilities. The keratinolytic activity increased over time, as evidenced by the increase in extracellular keratinase activity and release of soluble proteins and peptides. Protease activity peaked in the first 7 days and again on day 28 of culture. The release of ammonium and sulfate ions, associated with an increase in pH, reached its maximum on day 21. Three pigment-producing strains were among the most active in releasing large amounts of ammonium and sulfate ions. The biodegradation of feather waste by Trichophyton ajelloi strains can be used to produce fertilizers suitable for plants with high sulfur requirements.

Summary: The incomplete recycle of residual mulch film (RMF) in recent years has led to an increase in plastic fragments in soil, posing a serious threat to the soil ecological environment. In this study, seven potential plastic-degrading microorganisms were screened and identified from film-mulched vegetable fields. The degradation ability experiments showed that both single strains and mixed strains demonstrated varying levels of degradation of RMF.

Summary: This study investigated the degradation of heat-treated wood by brown rot fungi and found that the decay increased the hygroscopicity of wood in the decaying state. Furthermore, it was observed that heat-treated samples were more susceptible to fungal decay compared to untreated samples, which may be related to the increase in moisture content.
