Microbial Diversity in Heavy-metal Polluted Waters
Indigenious water microflora as well as the presence of metaland xenobiotic biotransforming bacteria were investigated in waters near the KCM Pb-Zn smelter, South Bulgaria. Content of As, Hg, Cd, Mn, Pb, Cu and Zn exceeded in times the maximum permission standart. Absence of some microbial groups demonstrated a change in the microbial community structure in the region. Ecotoxicology test ISO/DI...
متن کاملEffects of Soil Moisture and Nickel Contamination on Microbial Respiration Rates in Heavy Metal-Polluted Soils
Soil microorganisms may be both sensitive and resilient to various disturbances. The effects of a single stressor on soil microorganisms have been well studied, but only limited research has been carried out to test the effects of simultaneous action of diverse stressors. Soil samples were collected from a long-term polluted zinc and lead site and an unpolluted site. Modeling studies assumed sp...
متن کاملEffects of deposition of heavy-metal-polluted harbor mud on microbial diversity and metal resistance in sandy marine sediments.
Deposition of dredged harbor sediments in relatively undisturbed ecosystems is often considered a viable option for confinement of pollutants and possible natural attenuation. This study investigated the effects of deposition of heavy-metal-polluted sludge on the microbial diversity of sandy sediments during 12 months of mesocosm incubation. Geochemical analyses showed an initial increase in po...
متن کاملPhytoextraction of heavy metal polluted soils using Sedum plumbizincicola inoculated with metal mobilizing Phyllobacterium myrsinacearum RC6b.
The aim of this study was to investigate the effects of metal mobilizing plant-growth beneficial bacterium Phyllobacterium myrsinacearum RC6b on plant growth and Cd, Zn and Pb uptake by Sedum plumbizincicola under laboratory conditions. Among a collection of metal-resistant bacteria, P. myrsinacearum RC6b was specifically chosen as a most favorable metal mobilizer based on its capability of mob...
متن کاملAbundance and diversity of Archaea in heavy-metal-contaminated soils.
The impact of heavy-metal contamination on archaean communities was studied in soils amended with sewage sludge contaminated with heavy metals to varying extents. Fluorescent in situ hybridization showed a decrease in the percentage of Archaea from 1.3% +/- 0.3% of 4', 6-diamidino-2-phenylindole-stained cells in untreated soil to below the detection limit in soils amended with heavy metals. A c...
