A new strategy for heavy metal polluted environments: a review of microbial biosorbents
(MDPI, 2017)Persistent heavy metal pollution poses a major threat to all life forms in the environment due to its toxic effects. These metals are very reactive at low concentrations and can accumulate in the food web, causing severe ... -
Effect of bacterial inoculation of strains of pseudomonas aeruginosa, alcaligenes feacalis and bacillus subtilis on germination, growth and heavy metal (cd, cr, and ni) uptake of brassica juncea
(Taylor & Francis, 2016)Bacterial inoculation may influence Brassica juncea growth and heavy metal (Ni, Cr, and Cd) accumulation. Three metal tolerant bacterial isolates (BCr3, BCd33, and BNi11) recovered from mine tailings, identified as Pseudomonas ... -
Heavy metal concentration in soil in the tailing dam vicinity of an old gold mine in Johannesburg, South Africa†
(Agricultural Institute of Canada, 2016)Soil contamination with heavy metals is a serious concern to food production and human health. The present study was conducted to evaluate the impact of tailings from an old mining site on heavy metal contamination of soil. ... -
Identification and characterization of Cr-, Cd-, and Ni-tolerant bacteria isolated from mine tailings
(Taylor & Francis, 2017)Eleven bacterial strains were isolated from soil samples collected from mine tailings. Bacterial strains were checked for tolerance against heavy metals (Cr, Cd, Ni), using the agar dilution method. All the strains showed ... -
Microbial and plant-assisted bioremediation of heavy metal polluted environments: a review
(MDPI, 2017)Environmental pollution from hazardous waste materials, organic pollutants and heavy metals, has adversely affected the natural ecosystem to the detriment of man. These pollutants arise from anthropogenic sources as well ... -
A taxonomic revision of Commicarpus (Nyctaginaceae) in southern Africa
(Elsevier, 2013)A taxonomic revision of the genus Commicarpus in southern African is presented and includes a key to the species, complete nomenclature and a description of all infrageneric taxa. The geographical distribution, notes on ...
