Removal of heavy metals by biosorption 总被引:1,自引:0,他引:1
Industrialization and urbanization have resulted in increased releases of toxic heavy metals into the natural environment
comprising soils, lakes, rivers, groundwaters and oceans. Research on biosorption of heavy metals has led to the identification
of a number of microbial biomass types that are extremely effective in bioconcentrating metals. Biosorption is the binding
and concentration of adsorbate from aqueous solutions by certain types of inactive and dead microbial biomass. The novel types
of biosorbents presently reviewed are grouped under fungal biomass, biomass of non-living, dried brown marine algae, agricultural
wastes and residues, composite chitosan biosorbent prepared by coating chitosan, cellulose-based sorbents and bacterial strains.
The reports discussed in this review collectively suggest the promise of biosorption as a novel and green bioremediation technique
for heavy metal pollutants from contaminated natural waters and wastewaters. 相似文献

Textile effluents in natural waters pose environmental health problems if not treated to safe limits. Various bacterial species have the potential to degrade dyes. Here we studied the ability of Bacillus algicola to decolourise red, blue and yellow azo dyes. B. algicola was isolated from soil samples taken from a sanitary landfill site. Isolation and screening were performed using mineral salt medium. Dye-decolourising isolates were assessed in their capacity to decolourise dyes. Experiments were conducted at pH 6, 7 and 8, and 25, 35 and 45 °C. Phytotoxicity of the dyes and biodegradation products was assessed by seed germination tests. Results show that B. algicola gave the highest decolourisation at pH 8.0 and 25 °C in the presence of yeast extract as media supplement. B. algicola degraded the red and blue azo dyes by over 95%. The phytotoxicity results indicated that biodegradation products of the red and blue azo dyes were not toxic. Biodegradation products of the yellow dye were, however, toxic and considerably hindered germination. From these results, we infer that B. algicola has good potential for degrading and decolourising the red and blue test azo dyes. 相似文献
