Abstract Aims The present study aimed at: (i) verifying the suitability of pure sewage sludge (SS) as growing medium for hyperaccumulator species ( Pteris vittata , Odontarrhena chalcidica, Astragalus bisulcatus and Noccaea caerulescens ); (ii) evaluating removal As, Ni, Se Zn operated by chosen species; (iii) estimating potential metal yields (bio-ore production) connected monetary rewards in ...

The reuse of Pteris vittata plants for multiple phytofiltration cycles is a main issue to allow an efficient phytoremediation arsenic (As)-contaminated groundwater. Here, we assessed the capacity P. grown two on naturally As-contaminated drinking water (collected in Central Italy), spaced by growth cycle non-contaminated (N cycle). young plants, with extensive frond and root development, were s...

Antimonite (SbIII) is transported into plants via aquaglyceroporin channels but it is unknown in As-hyperaccumulator Ptreis vittata (PV). We tested the effects of SbIII analogs (arsenite-AsIII, glycerol, silicic acid-Si, and, glucose), antimonate (SbV) analog (phosphate-P), and aquaglyceroporin transporter inhibitor (silver, Ag) on the uptake of SbIII or SbV by PV gametophytes. PV gametophytes ...

Bacteria-mediated arsenic (As) transformation and their impacts on As and P uptake and plant growth in As-hyperaccumulator Pteris vittata (PV) were investigated under sterile condition. All As-resistant bacteria (9 endophytic and 6 rhizospheric) were As-reducers except one As-oxidizer. After growing two months in media with 37.5 mg kg(-1) AsV, As concentrations in the fronds and roots were 3655...

A greenhouse pot experiment was carried out to evaluate the efficiency of arsenic phytoextraction by the fern Pteris vittata growing in arsenic-contaminated soil, with or without the addition of selected rhizobacteria isolated from the polluted site. The bacterial strains were selected for arsenic resistance, the ability to reduce arsenate to arsenite, and the ability to promote plant growth. P...

Dargai District Malakand, Pakistan, is a tax-free zone that attracts many industrialists to install their plants in this area. Along with other industries, number of steel mills are polluting the natural environment locality. This study aimed evaluate heavy metals levels effluents and fabricate an efficient adsorbent from leaves growing on banks drainage lines industries having high phytoremedi...
