A combination of bioleaching and bioprecipitation for deep removal of contaminating metals from dredged sediment.
A linked microbial process comprising bioleaching with sulfate-oxidizing bacteria and bioprecipitation with sulfate-reducing bacteria operating sequentially was investigated to deeply removeExpand
Removal of Cr from tannery sludge by bioleaching method.
Bioleaching of Cr(Ill) from tannery sludge using the mixture of ingenuous iron- and sulfur-oxidizing bacteria was investigated in batch flasks. Experiments involved the adaptation of indigenous iron-Expand
Bioleaching of Cr from Tannery Sludge: The Effects of Initial Acid Addition and Recycling of Acidified Bioleached Sludge
A technologically feasible process called bioleaching was used to remove Cr from tannery sludge with Acidithiobacilli TS6 bacteria in this study. The buffering capacity of tannery sludge andExpand
Effect of Sludge Dissolved Organic Matter on Oxidation of Ferrous Iron and Sulfur by Acidithiobacillus Ferrooxidans and Acidithiobacillus Thiooxidans
Although two species of chemolithoautotrophic bacteria, Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans, are widely considered to be the main microorganisms that control the processExpand
Enhanced Cr bioleaching efficiency from tannery sludge with coinoculation of Acidithiobacillus thiooxidans TS6 and Brettanomyces B65 in an air-lift reactor.
Bioleaching process has been demonstrated to be an effective technology in removing Cr from tannery sludge, but a large quantity of dissolved organic matter (DOM) present in tannery sludge oftenExpand
Microwave-ultrasound assisted synthesis of β-FeOOH and its catalytic property in a photo-Fenton-like process.
In this study, nanoparticles of single-phase akaganeite (β-FeOOH) were synthesized by an ultrasound-microwave assisted method. The synthesis parameters were optimized by means of response surfaceExpand
Effects of sulfur forms on heavy metals bioleaching from contaminated sediments
The use of recyclable forms of sulfur will exclude the risk of sediment reacidification and reduce the cost of bioleaching process. Three different forms of sulfur (namely sulfur powder, prills andExpand
Significance of Oxygen Supply in Jarosite Biosynthesis Promoted by Acidithiobacillus ferrooxidans
Jarosite [(Na+, K+, NH4 +, H3O+)Fe3(SO4)2(OH)6] is an efficient scavenger for trace metals in Fe- and SO4 2--rich acidic water. During the biosynthesis of jarosite promoted by AcidithiobacillusExpand
Effect of sulphur concentration on bioleaching of heavy metals from contaminated dredged sediments
The sulphur‐based bioleaching process using sulphur‐oxidizing bacteria (SOB) has been demonstrated to be a feasible technology for removing heavy metals from contaminated sediments, but the excessExpand
Evolution of soil surface charge in a chronosequence of paddy soil derived from Alfisol
Abstract Limited information is available on the changes in surface electro–chemical properties of paddy soils during pedogenesis. This study evaluated the category, evolution and origin of soilExpand
