“…A down flow structured bed bioreactor (DFSBR) treatment of synthetic AMD treatment using sugar vinasse as an electron donor for SRB, resulted in efficient metal sulfide precipitation attributed to high microbial diversity and syntrophism of sulfate and metal reducers Geobacter and Desulfovibrio and fermenters such as Parabacteroides and Sulfurovum (Nogueira et al, 2021).…”

“…Currently, active and passive technologies utilizing sulfidogenic bioreactors involving SRB has become attractive for treatment and recovery of HM in acidic sulfatecontaining wastewater such as AMD. The performance including the microbial communities of sulfidogenic reactors treating AMD comprising fermentative-, acetogenic-, and SRB as well as methanogenic archaea has been documented (Sánchez-Andrea et al, 2014;Aoyagi et al, 2018;Ayangbenro et al, 2018;Xu and Chen, 2020;Nogueira et al, 2021). In addition, innate activity of diverse FeOB ranging from members of genera Metallibacterium, Ferrovum, Leptothrix, Sideroxydans, Bacillus, Gallionella, Leptospirillum, Acidithiobacillus, and Ferritrophicum are important for robust oxidative precipitation of Fe from AMD, suggesting their biotechnological relevance in the treatment of AMD impacted environment (Brantner et al, 2014).…”

Environmental degradation related to mining-generated acid mine drainage (AMD) is a major global concern, contaminating surface and groundwater sources, including agricultural land. In the last two decades, many developing countries are expanding agricultural productivity in mine-impacted soils to meet food demand for their rapidly growing population. Further, the practice of AMD water (treated or untreated) irrigated agriculture is on the increase, particularly in water-stressed nations around the world. For sustainable agricultural production systems, optimal microbial diversity, and functioning is critical for soil health and plant productivity. Thus, this review presents up-to-date knowledge on the microbial structure and functional dynamics of AMD habitats and AMD-impacted agricultural soils. The long-term effects of AMD water such as soil acidification, heavy metals (HM), iron and sulfate pollution, greatly reduces microbial biomass, richness, and diversity, impairing soil health plant growth and productivity, and impacts food safety negatively. Despite these drawbacks, AMD-impacted habitats are unique ecological niches for novel acidophilic, HM, and sulfate-adapted microbial phylotypes that might be beneficial to optimal plant growth and productivity and bioremediation of polluted agricultural soils. This review has also highlighted the impact active and passive treatment technologies on AMD microbial diversity, further extending the discussion on the interrelated microbial diversity, and beneficial functions such as metal bioremediation, acidity neutralization, symbiotic rhizomicrobiome assembly, and plant growth promotion, sulfates/iron reduction, and biogeochemical N and C recycling under AMD-impacted environment. The significance of sulfur-reducing bacteria (SRB), iron-oxidizing bacteria (FeOB), and plant growth promoting rhizobacteria (PGPRs) as key players in many passive and active systems dedicated to bioremediation and microbe-assisted phytoremediation is also elucidated and discussed. Finally, new perspectives on the need for future studies, integrating meta-omics and process engineering on AMD-impacted microbiomes, key to designing and optimizing of robust active and passive bioremediation of AMD-water before application to agricultural production is proposed.

“…The high relative abundance of Desulfomicrobium, Desulfovibrio, Geobacteraceae, and Desulfobulbus accounted for 17.91%, 7.40%, 6.15%, and 3.59% in the CCB-Ethanol. Desulfomicrobium, and Desulfovibrio, Desulfobulbus are the typical SRB were widely found in sulfate wastewater (Nogueira et al 2021). Among them, the relative abundance of Desulfovibrio was 8.73 times higher than in the CCB-Ethanol (7.40%) than in the OCB-Ethanol (0.76%), indicating that weak electrical stimulation signi cantly promoted the enrichment of Desulfovibrio.…”

Microbial electrolysis cells (MECs) have rapidly developed into a promising technology to treat sulfaterich wastewater that lacks electron donors. However, little is known regarding the effect of different carbon sources on the microbial community structure bioelectrochemical systems. This study sought to investigate the effect of different carbon sources (NaHCO 3 , ethanol, and acetate were employed as sole carbon source respectively) on the performance of sulfate-reducing biocathodes. The sulfate reduction e ciency enhanced by the bioelectrochemical systems was 8.09%−11.57% higher than that of opencircuit reference experiments. Furthermore, the optimum carbon source was ethanol with a maximum sulfate reduction rate of 170 mg L −1 d −1 in the bioelectrochemical systems. The different carbon sources induced signi cant differences in sulfate reduction e ciency as demonstrated by the application of a micro-electrical eld. The dominant sulfate-reducing bacteria that use NaHCO 3 and acetate as carbon sources were Desulfobacter and Desulfobulbus, whereas those that use ethanol as carbon source were Desulfomicrobium and Desulfovibrio. Our results suggest that ethanol is a more suitable carbon source for sulfate reduction in bioelectrochemical systems.

“…Adicionalmente, uma característica intrínseca das rotas de conversão de compostos orgânicos pelas BRS é o de geração de bicarbonato (HCO3 -) por vias biológicas (GIL-GARCIA et al, 2018;WANG et al, 2008) e a geração de sulfeto agir como um agente neutralizante ao consumir os íons de H + do meio reacional (GODOI et al, 2017;NOGUEIRA et al, 2021). Tal fato pode proporcionar uma redução ou até mesmo eliminação do uso de alcalinizantes químicos na etapa metanogênica das plantas de DA com separação de fases.…”
