BACKGROUND: Leaching kinetics of the roasted (at 600 ◦ C) chromite overburden of Sukinda mines Orissa, India, was studied with optimized data generated through response surface methodology (RSM) coupled with Box-Behnken design (BBD). The effects of

Leaching of nickel and cobalt from two physical grades (S1, 125–190 μm, coarser and S3, 53–75 μm, finer) of chromite overburden was achieved by treating the overburden (2% pulp density) with 21-d culture filtrate of an Aspergillus niger strain

Under certain conditions bacteria can act as a good biosorbent for different toxic heavy metals. However, no study on this aspect has been reported in case of acidophilic, heterotrophic, Gram-negative Acidiphilium strains, which are mostly resistant

The Acidiphilium strains inhabit acidic mine regions where they are subjected to occasional environmental stresses such as high and low temperatures, exposure to various heavy metals, etc. Change in morphology is one of the strategies that bacteria a

Oxalic acid is now considered as a useful chemical in various hydrometallurgical processes. For its massive applications in hydrometallurgy, cost-effective production of the acid is necessary. In this direction, fermentative production of the acid fr

Acidophilic bacteria of mine origin are ideal systems for studying microbial metal resistance because of their ability to grow in the presence of high concentrations of metal salts. We have previously shown that the metal-resistant transformants obta

China clay is an important mineral, which is used in the manufacture of ceramics and refractory, as also in other industries. Mined China clay contains iron oxides and silicates as impurity; if present in excess of a threshold level, the impurities a

When the highly metal-resistant acidophilic heterotrophic strain, Acidiphilium symbioticum KM2, was incubated with two Escherichia coli strains, viz. S17-1 (pSUP106) and K12, on a medium that supported growth of these two divergent species of differe

An Acidiphilium cryptum strain and two Acidiphilium symbioticum strains exhibited extremely high tolerance to CdSO4, growing at a concentration of 700 mmol l-1 or more in MGY medium (g l-1 composition: KCl, 0.1; MgSO4.7H2O, 0.25; (NH4)2SO4, 2.0; K2HP

Extraction of metals (Ni, Co) from chromite overburden of Sukinda mines of Orissa, India, with the culture filtrate of Aspergillus niger was studied. Results showed that the amounts of metals leached varied directly with reaction temperature and peri
