Abstract:

The discharge of effluents rich in sulphate and nitrate is of increasing concern, as the former leads to mineralisation of surface water, and the latter is a plant nutrient. A process is described whereby sulphate is reduced to sulphide under anaerobic conditions with producer gas as substrate. Sulphide stripped off is then converted to elemental sulphur by reacting it with biologically produced iron(III). The study consisted of laboratory batch and continuous experiments, as well as pilot scale studies. Sulphate was reduced to sulphide at a rate of 1.2 g SO4 1−1 d−1 with H2/CO as substrate, a

Abstract:

Thermophilic micro-organisms are known to oxidise pyrite and other iron sulphide minerals resulting in the production of acidic ferric sulphate solutions. In this study, the leach liquors generated from such bacterial oxidation were aged through a forced hydrolysis process to yield various iron oxyhydroxides and sulphates. The forced hydrolysis was carried out under a pH range of 1.9 to 9.0. Upon completion of aging, the precipitates generated were characterised using powder X-Ray diffractrometry. The XRD analyses revealed a production of a variety of iron oxyhydroxides and basic iron sulphate

Abstract:

Treatment of acid mine drainage (AMD) was successfully demonstrated using tobacco waste (dust and stem) as a metal cation adsorbent, pH modifier and carbon source for sulphate-reducing bacteria (SRB). Synthetic and industrial AMD wastewaters were used in batch adsorption and SRB facilitated bioremediation experiments. Up to absorbent loading of 80 g/L, metal removal increased. However, increases above 160 g/L did not offer a proportional increase. At an adsorbent loading of 80 g/L, the highest metal removals of 38, 41, 31 and 43% for iron, nickel, copper and zinc respectively were achieved. Th

Abstract:

Sulphate is considered to have been a major source of sulphide in strata-bound and stratiform base-metal sulphide deposits. Many of these deposits, however, appear to have been formed at moderate temperatures (<200 °C), which poses the question, By what mechanism(s) was sulphate reduced to sulphide? Two modes of reduction have been established experimentally: (1) catalysis by sulphate-reducing bacteria, which at present is only known to occur below ca. 100 °C; and (2) abiological reduction by ferrous iron or organic matter, which has only been clearly shown above ca. 250 °C.Several attempts

Ethanol is used as carbon and energy source.

Abstract:

AbstractIce-hosted sediments in glaciers and icebergs from Antarctica and Svalbard contain authigenic nanoparticulates of schwertmannite, ferrihydrite and goethite that formed during sulphide oxidation. These phases indicate the existence of subglacial biogeochemical hotspots containing fluids of low pH (2—4), rich in dissolved Fe(III) and sulphate. Nanophase Fe is partially bioavailable and potentially important to global biogeochemical cycles, since the flux delivered by icebergs to the Southern Ocean is comparable to the flux of soluble, bioavailable Fe from aeolian dust.

Nutrient bias of acid sulphate soils with overabundance of oxides and sulphates of iron and aluminum fabricates acidic nature in soil as well as inadequacy of other essential nutrients. Crop production in acid sulphate soil is found challenging due to the deteriorating nutrient status hence, this soil is deemed as problem soil. This study aims to concoct a multinutrient pellet for the enhancement of nutrient status in acid sulphate soil, using nutrient sources permitted in National Programme for Organic Production.

Abstract:

Many microorganisms have an affinity to accumulate metal ions onto their surfaces, which results in metal loading of the biomass. Microbial biomineralisation of iron produces a biomass, which is often highly magnetic and can be separated from water systems by the application of a magnetic field. This paper reports on the magnetic separation of biomass containing microbial iron oxide (Fe3O4, present within magnetotactic bacteria) and iron sulphide (Fe1-XS, precipitated extracellularly by sulphate reducing bacteria) in a single wire cell. Since such bacteria can be separated magnetically, their

Increased need of iron during pregnancy especially after 2nd trimester makes iron supplementation mandatory. Ferrous ascorbate is known to exist intact inside the gastrointestinal tract due to the stable chelation of iron with ascorbate. This compound does not dissociate due to any of the food inhibitors. The aim is to study the effectiveness of Ferrous Ascorbate and Ferrous sulphate in terms of compliance and cost effectiveness of management of anaemia in pregnancy.

After a 20-day “wash-out” period the ferrous methionate and ferrous sulphate were administered again by an elastic silicone tube into the crop. The serum concentrations of the iron were determined using a bioanalyser. Two pharmacokinetic approaches were used - compartmental and non-compartmental analysis.
