How to tackle the stringent sulfate removal requirements in mine water treatment-A review of potential methods.

Sulfate (SO) is a ubiquitous anion in natural waters. It is not considered toxic, but it may be detrimental to freshwater species at elevated concentrations. Mining activities are one significant source of anthropogenic sulfate into natural waters, mainly due to the exposure of sulfide mineral ores to weathering. There are several strategies for mitigating sulfate release, starting from preventing sulfate formation in the first place and ending at several end-of-pipe treatment options. Currently, the most w...

Effects of sulfate on simultaneous nitrate and selenate removal in a hydrogen-based membrane biofilm reactor for groundwater treatment: Performance and biofilm microbial ecology.

Effects of sulfate on simultaneous nitrate and selenate removal in a hydrogen-based membrane biofilm reactor (MBfR) for groundwater treatment was identified with performance and biofilm microbial ecology. In whole operation, MBfR had almost 100% removal of nitration even with 50 mg mL sulfate. Moreover, selenate degradation increased from 95% to approximate 100% with sulfate addition, indicating that sulfate had no obvious effects on nitrate degradation, and even partly promoted selenate removal. Short-...

Calcium ameliorates the toxicity of sulfate salinity in Brassica rapa.

Salinity stress in Brassica, often only associated with osmotic effects and the toxicity of Na, was more severe when applied as NaSO than as NaCl, indicating that SO ions had toxic effects as well. Application of 10 mM calcium in the form of CaCl in the growth medium of plants only slightly ameliorated growth impairment by NaCl and KCl, but almost completely prevented negative effects of NaSO and KSO on plant biomass production. This effect was calcium specific, as MgCl ameliorated sulfate toxicity to a m...

Isolation and Characterization of a Chinese Hamster Ovary Heparan Sulfate Cell Mutant Defective in Both Met Receptor Binding and Hepatocyte Growth Factor NK1/Met Signaling.

The up-regulation of hepatocyte growth factor/receptor, HGF/Met, signal transduction is observed in most of human cancers. Specific heparan sulfate structures enhance the HGF/Met signaling at both cell and animal-based model systems. Biochemical studies indicate that heparan sulfate interacts with HGF and a natural occurring splicing variant NK1 of HGF with similar affinity. However, it is currently unknown if cell surface heparan sulfate binds to Met at physiological conditions and if specific cell surface...

Enhanced sulfate and metal removal by reduced graphene oxide self-assembled Enterococcus avium sulfate-reducing bacteria particles.

Graphene oxide (GO) was introduced to Enterococcus avium strain BY7 sulfate-reducing bacteria culture as a carrier, GO was partially reduced by SRB to reduced graphene oxide (rGO). The rGO could further self-assemble Enterococcus avium strain BY7 sulfate-reducing bacteria to form BY-rGO particles. Growth and sulfate reduction activity of strain BY7 was promoted by rGO, which probably due to the protective effect of rGO, and enhanced electron transfer by rGO as electron shuttle. Effects of pH and temperature...

A novel combined process for efficient removal of Se(VI) from sulfate-rich water: Sulfite/UV/Fe(III) coagulation.

The efficient removal of Se(VI) from sulfate-rich water is challenging as most reported processes last for hours to days. In this study, a combined sulfite/UV/Fe(III) coagulation process was proposed for efficient Se(VI) removal from sulfate-rich water within a short time (∼1 h). In the presence of sulfate (1000 mg L), over 99% of Se(VI) (initially at 10 mg L) could be reduced by sulfite (5.0 mM) with a UV dose of 16 J cm (within 20 min) into Se(IV) as the sole observed product. An alkal...

Cryptic CH cycling in the sulfate-methane transition of marine sediments apparently mediated by ANME-1 archaea.

Methane in the seabed is mostly oxidized to CO with sulfate as the oxidant before it reaches the overlying water column. This microbial oxidation takes place within the sulfate-methane transition (SMT), a sediment horizon where the downward diffusive flux of sulfate encounters an upward flux of methane. Across multiple sites in the Baltic Sea, we identified a systematic discrepancy between the opposing fluxes, such that more sulfate was consumed than expected from the 1:1 stoichiometry of methane oxidation ...

Sulfation disposition of liquiritigenin in SULT1A3 overexpressing HEK293 cells: The role of breast cancer resistance protein (BCRP) and multidrug resistance-associated protein 4 (MRP4) in sulfate efflux of liquiritigenin.

This study aimed to investigate the cellular disposition of liquiritigenin via the sulfonation pathway and the role of efflux transporters in liquiritigenin sulfate excretion. The sulfonation disposition of liquiritigenin was investigated using SULT1A3 overexpressed HEK293 cells (HEK-SULT1A3 cells). Liquiritigenin generated one mono-sulfate metabolite (7-O-sulfate) in HEK-SULT1A3 cell lysate. And the sulfonation followed the Michaelis-Menten kinetic (V = 0.84 nmol/min/mg and K = 7.12 μM). Expec...

Supplementary l-lysine sources include l-lysine HCl and l-lysine sulfate. L-Lysine sulfate contains at least 50% l-Lys and other components as residues from the fermentation process, other amino acids, and other organic and inorganic substances, being an alternative to l-Lys HCl. The aim of this study was to evaluate the relative bioavailability (RBV) of l-Lys sulfate in comparison with l-Lys HCl and its effects on performance, blood parameters, intestinal functionality, and the apparent total tract digesti...

Absence of the sulfate transporter SAT-1 (Slc26a1) has no impact on oxalate handling by mouse intestine and does not cause hyperoxaluria or hyperoxalemia.

The anion exchanger SAT-1 (Sulfate Anion Transporter 1; Slc26a1), is considered an important regulator of oxalate and sulfate homeostasis but the mechanistic basis of these critical roles remain undetermined. Previously, characterization of the SAT-1 knockout (KO) mouse suggested the loss of SAT-1 mediated oxalate secretion by the intestine was responsible for the hyperoxaluria, hyperoxalemia and calcium oxalate urolithiasis reportedly displayed by this model. To test this hypothesis, we compared the transe...

Mucopolysaccharidoses are a group of lysosomal storage disorders (LSDs) characterized by the accumulation of glycosaminoglycans (GAGs). Recently, LC-MS/MS has been widely applied in GAGs analysis combined with different sample preparations for cleaving GAGs to disaccharide units. The aim of the present is paper is to present a new method for the simultaneous quantification of urinary dermatan sulfate (DS) and heparan sulfate (HS) by LC-MS/MS, after butanolysis reaction. Chromatographic separation was achiev...

Elucidating the effects of starvation and reactivation on anaerobic sulfidogenic granular sludge: Reactor performance and granular sludge transformation.

In biological wastewater treatment, the bacteria starvation always challenges the stability of system operation. Yet, the effects of starvation and possibility of reactivation are less understood for anaerobic sulfidogenic system. Sulfidogenic systems use sulfate as electron acceptor for organic chemical oxygen demand (COD) degradation, so it will encounter two kind of starvations: (i) complete stoppage of wastewater flow (named complete food starvation) and (ii) remaining organic COD but with very low leve...
