A heavy metal-resistant bacterial strain was isolated from heavy metal-contaminated soils and identified as Burkholderia sp. J62 based on the 16S rDNA gene sequence analysis. The heavy metal- and antibiotic resistance, heavy metal solubilization of the isolate were investigated. The isolate was also evaluated for promoting plant growth and Pb and Cd uptakes of the plants from heavy metal-contam...

Faba bean plants (Vicia faba) showed remarkable resistant to wilt disease caused by Fusarium solani pv. Phaseoli when watered with a mixture of heavy metal at a concentration 10mg/L. However the use of Zn, Pb alone slightly increases the susceptibility of bean plants to Fusarium wilt. Plants exposed to Cd or Cu treatment accelerate the symptoms appearance in infected plant. The toxicity of a si...

The biomass of filamentous fungi is an important cost-effective biomass for heavy metal biosorption. However, use of free fungal cells can cause difficulties in the separation of biomass from the effluent. In this study, we immobilized the living conidia of the heavy metal-resistant Penicillium janthinillum strain GXCR by polyvinyl alcohol (PVA)-sodium alginate (SA) beads to remove heavy metals...

Effects of different heavy metals on Vibrio harveyi, V. fischeri, Photobacterium phosphoreum and P. leiognathi were examined. Checkerboard assay was used for the detection of the natural metal tolerance levels of a large number of marine luminous eubacteria. 57 strains of luminous bacteria were investigated for their natural patterns of heavy metal tolerance. The behaviors of these strains were...

Different forms of heavy metals affect biochemical systems in characteristic ways that cannot be detected with typical metal analysis methods like atomic absorption spectrometry. Further, using living systems to analyze interaction of heavy metals with biochemical systems can be laborious and unreliable. To generate a reliable easy-to-use biologically-based biosensor system, the entire human me...

A study to determine the heavy metal content in paddy soils was carried out at KETARA, Besut, Terengganu, Malaysia. The objective of the study was to determine the heavy metal content of the soil types in the study area. The heavy metals studied were Pb, Cd, Cu, Zn, Fe, Mn and Cr. Heavy metals in the soil were extracted using the sequential extraction method, which consists of four fractions na...
