Optimization of Plant Growth-Promoting Bacteria-Assisted Phytostabilization of Mine Tailings.
Recent studies have indicated that plant growth-promoting bacteria (PGPB) can improve revegetation of arid mine tailings as measured by increased biomass production. The goals of the present study were first to evaluate how mode of application of known PGPB affects plant growth, and second to evaluate the effect of this inoculation on rhizosphere microbial community structure. PGPB application ...
متن کاملBacillus pumilus ES4: candidate plant growth-promoting bacterium to enhance establishment of plants in mine tailings.
Three plant growth-promoting bacteria (PGPB; Bacillus pumilus ES4, B. pumilus RIZO1, and Azospirillum brasilense Cd) were tested for their ability to enhance plant growth and development of the native Sonoran Desert shrub quailbush (Atriplex lentiformis) and for their effect on the native bacterial community in moderately acidic, high-metal content (AHMT) and in neutral, low metal content natur...
متن کاملBioremediation Potential Assessment of Plant Growth-Promoting Autochthonous Bacteria: a Lignite Mine Case Study
Coal and lignite play a major energy supply role in many European countries, including Bosnia and Herzegovina. Yet mining activities are a heavy source of ecosystem contamination, posing significant environmental threats. The primary goal of this study was to isolate and identify autochthonous lignite mine spoil bacteria and evaluate their potential in bioremediation of these polluted soils. Tw...
متن کاملPhytostabilization of Mine Tailings in Arid and Semiarid Environments—An Emerging Remediation Technology
OBJECTIVE Unreclaimed mine tailings sites are a worldwide problem, with thousands of unvegetated, exposed tailings piles presenting a source of contamination for nearby communities. Tailings disposal sites in arid and semiarid environments are especially subject to eolian dispersion and water erosion. Phytostabilization, the use of plants for in situ stabilization of tailings and metal contamin...
متن کاملPlants from the abandoned Nacozari mine tailings: evaluation of their phytostabilization potential
Phytostabilization is a remediation technology that uses plants for in-situ stabilization of contamination in soils and mine tailings. The objective of this study was to identify native plant species with potential for phytostabilization of the abandoned mine tailings in Nacozari, Sonora in northern Mexico. A flora of 42 species in 16 families of angiosperms was recorded on the tailings site an...
