An anaerobic N2-fixing Clostridium sp. solubilized Cd, Cr, Ni, Pb, and Zn coprecipitated with
goethite (a-FeOOH) by (i) direct action due to enzymatic reduction of ferric iron and the …

The impact of autochthonous anaerobic bacteria on the release of metals in river sediment
was studied. The sediments were characterized and bacterial activity was monitored in a …

Bioleaching of metals can be achieved in sewage sludge using Thiobacillus ferrooxidans,
which obtains its energy requirements from the oxidation of added ferrous iron. The purpose …

Anaerobic microbial dissolution of several crystalline, water-insoluble forms of metal oxides
commonly associated with the waste from energy production was investigated. An anaerobic …

Indigenous iron‐oxidizing bacteria in soil were acclimated in three different contaminated
soils to remove toxic heavy metals. The adaptation was carried out at a pH of 4.0 and a room …

The removal of heavy metals (Cr, Cu, Zn, Ni and Pb) from anaerobically digested sludge
from the Yuen Long wastewater treatment plant, Hong Kong, has been studied in a batch …

Reduction of pedogenic iron oxides by the activity of Clostridium butyricum was studied in
model experiments under controlled conditions of pH, particle size (63 to 125 μm), glucose …

Nitrate-reducing bacteria (Pseudomonas fluorescens and Alcaligenes sp.) as well as
extracellular compounds from these bacteria increased the dissolution rate of iron and …

Studies were carried out to elucidate the nature and importance of Fe3+ reduction in
anaerobic slurries of marine surface sediment. A constant accumulation of Fe2+ took place …

Heavy metal-loaded sewage sludge was leached abiotically using FeCl2 and FeCl3 which
are applied in waste water treatment plants to eliminate phosphate and for coagulation. Due …
