Soil amendments can be used to cost-effectively reduce the bioavailability and mobility of toxic metals in contaminated soils. In this study a field demonstration was conducted at a Pb-contaminated… Expand
A comparative study of cadmium phytoextraction by accumulator and weed species.
Phytoextraction has shown great potential as an alternative technique for the remediation of metal contaminated soils. The objective of this study was to investigate cadmium (Cd) phytoextraction… Expand
Phosphate-induced lead immobilization from different lead minerals in soils under varying pH conditions.
This study investigated phosphate-induced lead immobilization from different Pb minerals in soils under varying pHs. Four soils were used, including one Pb-contaminated soil (NC-Soil) and three soils… Expand
Heavy metal interactions with phosphatic clay: sorption and desorption behavior.
Heavy metals produced and released during agricultural and industrial activities may pose a serious threat to the environment. This study investigated the effectiveness of phosphatic clay, a… Expand
Production and optimization of a commercially viable alkaline protease from a haloalkaliphilic bacterium
Twenty five haloalkaliphilic bacterial strains were isolated from sea water along the Coastal Gujarat (India) and screened for their ability to secret alkaline proteases. Among them, a potent strain… Expand
Production of Extracellular Halo-alkaline Protease from a Newly Isolated Haloalkaliphilic Bacillus sp. Isolated from Seawater in Western India
SummaryHaloalkaliphilic, gram positive, aerobic, coccoid Bacillus sp. Po2 was isolated from a seawater sample in Gujarat, India. On the basis of 16s rRNA gene homology, Po2 was 95% related to… Expand
Characterization of aqueous lead removal by phosphatic clay: equilibrium and kinetic studies.
Immobilization of heavy metals from contaminated environments is an emerging field of interest from both resource conservation and environmental remediation points of view. This study investigated… Expand
