Summary: The sulfate-reducing bacterium Desulfovibrio vulgaris promotes microbiologically influenced corrosion (MIC) of CoCrFeMnNi high entropy alloy (HEA) and leads to pitting corrosion. D. vulgaris causes the formation of metal sulfides and thinning of passive film. The relative expression of hydrogenase genes hydA and hydB in the biofilms significantly increases, indicating the importance of indirect electron transfer in promoting HEA MIC by D. vulgaris under starvation.

Summary: The reduction of sulfate to hydrogen sulfide by microbes is highly undesirable in industrial settings. This study demonstrates that Desulfovibrio desulfuricans can be coated with locally generated metal nanoparticles, with individual cells carrying more than 100 times their mass of palladium metal. Moreover, the study reveals the effect of metal coating on metabolism and replication, with bacteria unable to reduce sulfate to sulfide beyond a specific threshold. These findings present a foundation for a novel means of modulating the activity of sulfate-reducing bacteria.

Summary: This study reported the effects of Cu(II) stress on a model SRB, Desulfovibrio alaskensis G20. The results indicated that the expression of genes was massively modulated at different Cu(II) concentrations, and changes in inorganic ion transporters, translation machinery, DNA transcription, and signal transduction were observed.

Summary: The marine sulfate reducer Desulfobacterium autotrophicum adapts to substrate limitation through complete lactate oxidation and differential overexpression of genes involved in amino acid metabolism, and reroutes carbon metabolism in response to sulfate limitation. Upregulation of putative sulfate transporters suggests a key role of SRM in controlling sulfate concentration.

Summary: A new strain of Psychrodesulfovibrio, named Desulfovibrio mangrovi sp. nov., was isolated from mangrove sediments in Futian Mangrove Nature Reserve in Shenzhen, China. The strain is a sulfate-reducing bacterium with biogeochemical significance, and it can utilize a variety of electron donors and reduce different compounds. Phylogenetic analysis revealed its close relationship with Desulfovibrio subterraneus HN2(T), suggesting a transfer to the genus Psychrodesulfovibrio.

Summary: This study aims to investigate the diversity and activity of sulfate-reducing bacteria (SRB) in the camel gut. It reveals the presence of an abundant SRB community in the feces of Bactrian camels through 16S rRNA gene profiling, SRR measurement, and targeted cultivation. The findings shed light on the activity of SRB in the camel gut.

Summary: The H-cluster is the catalytic cofactor of [FeFe]-hydrogenase, and its diiron site can be studied by IR spectroscopy. Previous research identified an oxidized and protonated H-cluster species, HoxH, which is influenced by pH and the presence of external reductants. Recent studies suggest that the accumulation of HoxH is not dependent on specific reductants, but rather on the protonation state and deprotonation ability of the H-cluster.

Summary: Sulfate-containing wastewater poses a serious threat to the environment and human health, and microbial technology has great potential for its treatment. Nano-photocatalysts have been found to promote the growth and metabolic activity of non-photosynthetic microorganisms, but they can also induce oxidative stress and damage cells. This paper investigates the mechanism and regulation strategy of cadmium sulfide nanoparticles (CdS NPs) on the growth and sulfate reduction process of sulfate-reducing bacteria, providing important theoretical guidance and technical support for the treatment of sulfate-containing wastewater.

Summary: Recent studies have shown that sulfate reducing bacteria play an important role in nitrogen cycling, especially in oligotrophic coastal and benthic environments. A cellular model was developed to study the growth of sulfate reducers under different nitrogen availabilities. The model confirmed that these bacteria prefer to use ammonium rather than fix nitrogen for growth. This study contributes to a better understanding of anaerobic heterotrophic diazotrophs in environments with fluctuating nitrogen conditions.

Summary: Magnetotactic bacteria synthesize magnetosomes composed of magnetite and/or greigite nanoparticles in cells. The study reports the isolation and characterization of a novel sulfate-reducing magnetotactic bacterium FSS-1, which belongs to the genus Desulfovibrio. Strain FSS-1 is a strict anaerobe, producing bullet-shaped magnetite nanoparticles and responding to external magnetic fields.

Summary: Sulfate reducing bacteria (SRB) is a promising alternative biological treatment for immobilization of heavy metals. This study investigated the immobilization efficacy of a strain isolated from a metal smelter immobilized on biochar (BIC) for Cd2+ and Pb2+ under various conditions. The results showed that BIC had higher resistance to Cd2+ and Pb2+ compared to separate strain HY-1 and biochar. The optimal immobilization conditions were 3 days, pH 8.0, 30°C, biochar addition of 0.6 g/L, and initial Cd2+ and Pb2+ concentrations of 5 and 30 mg/L, respectively. The immobilization products were confirmed to be CdS and PbS. These findings suggest that BIC is a promising method for immobilizing Cd2+ and Pb2+ from acid mine drainage.

Summary: The study analyzed the influence of metals on the activity and composition of sulfate-reducing bacteria (SRB), finding that an increase in metal concentration led to decreased SRB activity. The more toxic metals, such as Cd and Cu, were associated with less SRB and more fermenters in the microbial community, while less toxic metals like Cr and Zn had a higher abundance of SRB genera. An isolated Desulfovibrio species may have implications for future bioremediation studies in neutral pH effluents contaminated by metals.
