“…The inoculation of phenol-degrading bacteria (T3), however, would have decreased the contaminant level but at the expense of oxygen (Chen et al, 2010, Demoling and Bååth, 2008). While in vegetated reactors (T4), comparatively high removal can be attributed to the continuous uptake of the pollutant as well the potential of transporting atmospheric oxygen to the rhizosphere of P. australis (Van der Werff, 1991). In the bacterial assisted vegetated reactors (T5), successful interactions between plant-roots and rhizospheric bacteria are obvious to be established causing diffusion of surrounding oxygen into the plant rhizosphere as well as removal of contaminant load with the passage of time (Morris and Monier, 2003, Vymazal, 2010, Vymazal, 2013).…”

“…The species grows in marshes, swamps, and wet waste areas and therefore can be exploited in FTWs for the remediation of wastewaters. In principle, the species allows adsorption of the organic contaminants to the roots, without being translocated to aboveground plant parts, rendering it suitable for the removal of organic volatile compounds (Van der Werff, 1991). Moreover, members of the helophytic grasses are able to transport atmospheric oxygen to the rhizosphere hence helping them survive in waterlogged conditions.…”

Helophytic plants contribute significantly in phytoremediation of a variety of pollutants due to their physiological or biochemical mechanisms. Phenol, which is reported to have negative/deleterious effects on plant metabolism at concentrations higher than 500 mg/L, remains hard to be removed from the environmental compartments using conventional phytoremediation procedures. The present study aims to investigate the feasibility of using P. australis (a helophytic grass) in combination with three bacterial strains namely Acinetobacter lwofii ACRH76, Bacillus cereus LORH97, and Pseudomonas sp. LCRH90, in a floating treatment wetland (FTW) for the removal of phenol from contaminated water. The strains were screened based on their phenol degrading and plant growth promoting activities. We found that inoculated bacteria were able to colonize in the roots and shoots of P. australis, suggesting their potential role in the successful removal of phenol from the contaminated water. Pseudomonas sp. LCRH90 dominated the bacterial community structure followed by A. lowfii ACRH76 and B. cereus LORH97. The removal rate was significantly high when compared with the individual partners, i.e., plants and bacteria separately. The plant biomass, which was drastically reduced in the presence of phenol, recovered significantly with the inoculation of bacterial consortia. Likewise, highest reduction in chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total organic carbon (TOC) is achieved when both plants and bacteria were employed. The study, therefore, suggests that P. australis in combination with efficient bacteria can be a suitable choice to FTWs for phenol-degradation in water.

“…It is tolerant to a broad ecological range, colonizing different habitat types, such as riverbanks, ditches, littoral zones of lakes, fens, bogs and salt-marshes. This sub-cosmopolite species can grow in oligotrophic to eutrophic conditions, but it seems to be favoured in nutrient-rich sites [4]. The common reed can also withstand different pollutants, including heavy metals.…”

Phragmites australis (Cav.) Steud. is one of the most dominant and common species in wetland ecosystems from temperate regions worldwide [1][2][3]. It is tolerant to a broad ecological range, colonizing different habitat types, such as riverbanks, ditches, littoral zones of lakes, fens, bogs and salt-marshes. This sub-cosmopolite species can grow in oligotrophic to eutrophic conditions, but it seems to be favoured in nutrient-rich sites [4]. The common reed can also withstand different pollutants, including heavy metals. For this reason, it is often used for the treatment of industrial or agricultural wastewaters [5-9], for phytoremediation [10-12] and even for the removal of harmful microorganisms due to its allelopathic effect [13].In some areas of the world this grass is regarded as an aggressive invasive species [14][15][16][17]. The phenomenon is prominent in the USA where the Eurasian subspecies P. australis subsp. australis outcompetes the native, recently described, P. australis subsp. americanus Saltonstall, P.M. Peterson & Soreng, displacing the authoctonous populations [18]. For this reason, in N-America and Canada P. australis subsp. australis was included among the highest priority invasive species [19][20][21][22][23][24]. On the other side, reed beds represent valuable ecosystems for biodiversity conservation, although they are both usually

Background and aims Measuring specific ion fluxes from different regions of the root under practical physiological conditions is crucial for understanding metal uptake mechanisms by plants. Methods We developed and tested a neutral carrierbased liquid-membrane Pb 2+ and Cu 2+ ion selective microelectrode (ISME) to investigate ion-transport processes along the roots of three common wetland plant species. Results The Pb 2+ and Cu 2+ ISME exhibited a Nernstian response with Pb 2+ and Cu 2+ activities as low as 1.0 nM and 1.0 μM in deionized water and simulated soil solution, respectively. Phragmites australis had a region of Cu 2+ release for approximately the first 200 μm, while it exhibited Pb 2+ and Cd 2+ outward net flux up to the first 500 μm. Although in older sections of the root of Phragmites australis there were areas of influx of Cu 2+ , Pb 2+ and Cd 2+ , the overall influx was much smaller than that of Typha latifolia or Canna indica. Such a reduced uptake and/or an increased efflux of metal ions across the root-cell plasma-membrane might explain the higher resistance of Phragmites australis to metals, at least in part. Conclusions The Pb 2+ and Cu 2+ ISMEs are shown to permit detailed investigation of heavy-metal ion transport in plant roots, especially for plants used for phytoremediation.
