The Sulfate reduction, Autotrophic denitrification and Nitrification Integrated (SANI) process is a sulfur cycle-based biological carbon and nitrogen removal process that has been developed in Hong Kong to close the loop between the hybrid water supply and saline sewage treatment. The major bioreactor of this new technology is a Sulfate-Reducing Up-flow Sludge Bed (SRUSB) that convers organics ...

• Acidic MIWs with high SO 4 2- content were mitigated by SRB at low temperature. neutralized alkalinity generated in a sulfidogenic bioreactor. High SRRs temperature achieved. Relative abundance of increased during treatment actual MIWs. Metals removed off-line or in-line precipitation. The aim this study was to develop biological method for the simultaneous removal sulfate and metals from aci...

The main intention of this study to understand the microbial consortium of Sulphate Reducing Bacteria(SRB) and Sulphure oxidizing bacteria (SOB) on Extra polymeric substance produced by Pseudomonas sp., with combination of E-coli. In stressing the importance of anaerobic corrosion by SRB, corrosive effects of acids produced by microorganisms may be overlooked Sulphur oxidizers chiefly of the ge...

The pathway of electrons required for the reduction of sulfate in sulfate-reducing bacteria (SRB) is not yet fully characterized. In order to determine the role of a transmembrane protein complex suggested to be involved in this process, a deletion in Desulfovibrio vulgaris Hildenborough was created by marker exchange mutagenesis that eliminated four genes putatively encoding the QmoABC complex...

The applicability of anaerobic baffled reactor (ABR) was investigated for the treatment of acidic (pH 4.5-7.0) wastewater containing sulfate (1000-2000 mg/L) and Zn (65-200mg/L) at 35 degrees C. The ABR consisted of four equal stages and lactate was supplemented (COD/SO(4)(2-)=0.67) as carbon and energy source for sulfate reducing bacteria (SRB). The robustness of the system was studied by decr...

Sulfate-reducing bacteria (SRB) represent a group of prokaryotic microorganisms that are widely spread in the anoxic environment (seabed, riverbed and lakebed sediments, mud, intestinal tract humans animals, metal surfaces). SRB species also have an impact on processes occurring including connections between their presence inflammatory bowel disease (IBD). Since these can develop antimicrobial ...

Communities of anaerobic methane-oxidizing archaea (ANME) and sulfate-reducing bacteria (SRB) grow slowly, which limits the ability to perform physiological studies. High methane partial pressure was previously successfully applied to stimulate growth, but it is not clear how different ANME subtypes and associated SRB are affected by it. Here, we report on the growth of ANME-SRB in a membrane c...

The anaerobic digestion of sewage sludge is highly sensitive to high zinc concentrations. Although sulfate-reducing bacteria (SRB) activity can negatively affect methanogenesis, SRB-mediated metal sulfide precipitation alleviate toxicity. A series mesophilic batch experiments was performed for the biomethane potential three different samples 74 days using background content, alone or in combina...

Fluvial sediments, soils, and natural waters in northern Chile are characterized by high arsenic (As) content. Mining operations in this area are potential sources of As and other metal contaminants, due to acid mine drainage (AMD) generation. Sulfate Reducing Bacteria (SRB) has been used for the treatment of AMD, as they allow for the reduction of sulfate, the generation of alkalinity, and the...

<p>In the presence of nitrogen oxides, nitrate-reducing bacteria (NRB) may use nitrate as an electron acceptor, reduce to nitrite, and finally convert nitrite or ammonium (NO N2O). Studies have shown that BCX (Bio-Competitive Exclusion) is a viable , ecologically benign, low-cost technique for regulating NRB in its first phases study application. More precisely, Pseudomonas sp. isolate fr...
