“…increase water-soluble and exchangeable Cd content in contaminated soil. This in turn enhanced both plant biomass and uptake of Cd of in Brassica juncea (Belimov et al 2005;Fuloria et al 2009). Similar observations were also found in case of soybean inoculated with Pseudomonas putida 62 BN and Pseudomonas monteilli 97AN as well as canola inoculated with Pseudomonas tolaasii ACC23, Pseudomonas fluorescens ACC9, Alcaligenes sp.…”

Cadmium (Cd) contamination of rice is found in areas irrigated by wastewater from mines. Cd contamination of rice fields can also result from the application of Cd-rich phosphate fertilizers. As a consequence, millions of tons of rice are discarded. In Asia, irrigated paddy-based cropping systems provide rice grains as food for about 2 billion people. A daily intake of 20-40 μg Cd from rice is reported in regions where rice is used as a food. Daily rice Cd intake leads to diseases such as bone mineralization. Hence, Cd minimization in rice is needed. This article reviews sustainable agriculture and molecular techniques that prevents Cd uptake in rice. Cadmium minimization can be done either by field remediation or change in plant functions. Organic farming decreases Cd uptake and remediates crop fields. Cd hyperaccumulator plants and Cd immobilizing microbes can be used for field remediation. Cd amount in rice can be controlled by gene families that code for putative transition metal transporters or metal chaperones and quantitative trait loci (QTL). Generation of Cd excluder rice is possible by transgenics.

“…Adsorption of Heavy Metals by P. validus demonstrated that mesophilic bacterial activity was maximum at moderate temperature ( Figure 5), as has also been reported by Fuloria, Saraswat, and Rai (2009). At pH 6.0, the rate of FeS biooxidation was highest, whereas at pH 7.0 it geared, which may be due to the formation of ferric hydroxide jarosite ( Figure 6).…”

The present investigation was carried out to isolate bacterial strains from soil/mud samples of metal-polluted environment to check whether the natural adaptation of microbes has equipped them for bioremediation of toxic heavy metals. The primary and secondary screening resulted in 50 mesophilic autotrophic isolates of microbial consortium adapted for metal tolerance and bioadsorption potentiality. The multimetal tolerance in bacterial strain was developed by sequential transfer to higher concentrations of Cd, Cr, Cu, Pb, Ni, and Zn. The isolates were checked for their biosolubilization potential with copper-containing metal sulfide ores, viz. chalcopyrite exhibited 64% and covellite 54% solubilization in the presence of 10 −3 M multiple heavy metals on the fifth day at 35 • C and pH 6.0. Metal adsorption of highly potential isolate, i.e., Paenibacillus validus MP5, studied by inductively coupled plasma optical emission spectroscopy (ICP-OES), showed maximum adsorption of Zn 27%, followed by Ni and Cd 16%, Cr 15%, Co 9%, and Pb 7.5% in chalcopyrite, which suggested its possible role in decontamination of metal-polluted sites.
