57Fe as a Tracer of Bacterially Mediated Iron Mobilization in Lake Sediments

Autor: W. D. Gould, C. W. Smith, S. Alpay, M. Pawlak, M. Skaff, Lyne Lortie

Publikováno v: Geomicrobiology Journal. 25:167-180

In simulation experiments the stable isotope, 57 Fe, was used as a novel tracer of iron transport to investigate the role of microbial activity on the distribution/redistribution of metals in lake sediments. A series of microcosm sediment columns was

The onset of anthropogenic activity recorded in lake sediments in the vicinity of the Horne smelter in Quebec, Canada: Sulfur isotope evidence

Autor: Lyne Lortie, W. D. Gould, S. Alpay, F. Rosa, Bernhard Mayer

Publikováno v: Applied Geochemistry. 22:397-414

Contents and δ34S values of several S compounds, enumerations of S-reducing bacteria (SRB) and Fe-reducing bacteria (IRB), and Fe, Pb and In concentrations were determined for 210Pb-dated sediment cores from two lakes in Quebec, Canada. Both lakes a

Use of activated carbon as a support medium for H2S biofiltration and effect of bacterial immobilization on available pore surface

Autor: David Tee Liang, X G Chen, W D Gould, Y L Ng, Lawrence Choon Chiaw Koe, Anli Geng, Rong Yan

Publikováno v: Applied Microbiology and Biotechnology. 66:259-265

The use of support media for the immobilization of microorganisms is widely known to provide a surface for microbial growth and a shelter that protects the microorganisms from inhibitory compounds. In this study, activated carbon is used as a support

Biological removal of ammonia and nitrate from simulated mine and mill effluents

Autor: Pierre L. Bedard, David W. Koren, W. D. Gould

Publikováno v: Hydrometallurgy. 56:127-144

Although nitrification/denitrification processes have been used to remove ammonia and nitrate from municipal and industrial processes, there are few reported results on the removal of these ions from mine effluents. Ammonia and nitrate are present in

18O incorporation into sulphate during the bacterial oxidation of sulphide minerals and the potential for oxygen isotope exchange between O2, H2O and oxidized sulphur intermediates

Autor: S. Rajan, R. G. L. McCready, W. D. Gould, H.R. Krouse

Publikováno v: Earth and Planetary Science Letters. 107:90-94

Experiments were conducted using18O-enriched oxygen or water in an attempt to determine the source of oxygen incorporated into the sulphate ions produced during the bacterial oxidation of a metal sulphide. The initial results indicated that18O2 was i

Batch experiment on H2S degradation by bacteria immobilised on activated carbons

Autor: R, Yan, Y L, Ng, X G, Chen, A L, Geng, W D, Gould, H Q, Duan, D T, Liang, L C C, Koe

Publikováno v: Water science and technology : a journal of the International Association on Water Pollution Research. 50(4)

Biological treatments of odorous compounds, as compared to chemical or physical technologies, are in general ecologically and environmentally favourable. However, there are some inefficiencies relative to the media used in biofiltration processes, su

Removal of odorous sulphur-containing gases by a new isolate from activated sludge

Autor: A L, Geng, X G, Chen, W D, Gould, Y L, Ng, R, Yan, C C, Lee, D T, Liang

Publikováno v: Water science and technology : a journal of the International Association on Water Pollution Research. 50(4)

Biological treatment of odorous sulphur-containing compounds is attracting attention due to its benign eco-friendliness, energy-savings and low operating costs. As the biological treatment efficiency of dimethylsulphide (DMS) reported was often low a
