Abstract
Juncus acutus, acknowledged through its indigenous nomenclature "samar", is part of the Juncaceae taxonomic lineage, bearing considerable import as a botanical reservoir harboring conceivable therapeutic attributes. Its historical precedence in traditional curative methodologies for the alleviation of infections and inflammatory conditions is notable. In the purview of Eastern traditional medicine, Juncus species seeds find application for their remedial efficacy in addressing diarrhea, while the botanical fruits are subjected to infusion processes targeting the attenuation of symptoms associated with cold manifestations. The primary objective of this study was to unravel the phytochemical composition of distinct constituents within J. acutus, specifically leaves (JALE) and roots (JARE), originating from the indigenous expanse of the Nador region in northeastern Morocco. The extraction of plant constituents was executed utilizing an ethanol-based extraction protocol. The subsequent elucidation of chemical constituents embedded within the extracts was accomplished employing analytical techniques based on high-performance liquid chromatography (HPLC). For the purpose of in vitro antioxidant evaluation, a dual approach was adopted, encompassing the radical scavenging technique employing 2,2-diphenyl-1-picrylhydrazyl (DPPH) and the total antioxidant capacity (TAC) assay. The acquired empirical data showcase substantial radical scavenging efficacy and pronounced relative antioxidant activity. Specifically, the DPPH and TAC methods yielded values of 483.45 ± 4.07 µg/mL and 54.59 ± 2.44 µg of ascorbic acid (AA)/mL, respectively, for the leaf extracts. Correspondingly, the root extracts demonstrated values of 297.03 ± 43.3 µg/mL and 65.615 ± 0.54 µg of AA/mL for the DPPH and TAC methods. In the realm of antimicrobial evaluation, the assessment of effects was undertaken through the agar well diffusion technique. The minimum inhibitory concentration, minimum bactericidal concentration, and minimum fungicidal concentration were determined for each extract. The inhibitory influence of the ethanol extracts was observed across bacterial strains including Staphylococcus aureus, Micrococcus luteus, and Pseudomonas aeruginosa, with the notable exception of Escherichia coli. However, fungal strains such as Candida glabrata and Rhodotorula glutinis exhibited comparatively lower resistance, whereas Aspergillus niger and Penicillium digitatum exhibited heightened resistance, evincing negligible antifungal activity. An anticipatory computational assessment of pharmacokinetic parameters was conducted, complemented by the application of the Pro-tox II web tool to delineate the potential toxicity profile of compounds intrinsic to the studied extracts. The culmination of these endeavors underpins the conceivable prospects of the investigated extracts as promising candidates for oral medicinal applications.

Abstract
The microbiome associated with plants used in phytodepuration systems can boost plant growth and services, especially in ecosystems dealing with recalcitrant compounds, hardly removed via traditional wastewater (WW) treatments, such as azo-dyes used in textile industry. In this context, we aimed to study the cultivable microbiome selected by Phragmites australis plants in a Constructed Wetland (CW) in Morocco, in order to obtain candidate inoculants for the phytodepuration of azo-dye contaminated WW. A collection of 152 rhizospheric and endophytic bacteria was established. The strains were phylogenetically identified and characterized for traits of interest in the phytodepuration context. All strains showed Plant Growth Promotion potential in vitro and 67% of them significantly improved the growth of a model plant in vivo compared to the non bacterized control plants. Moreover, most of the isolates were able to grow in presence of several model micropollutants typically found in WW, indicating their potential use in phytodepuration of a wide spectrum of effluents. The six most promising strains of the collection were tested in CW microcosms alone or as consortium: the consortium and two single inocula demonstrated to significantly increase the removal of the model azo-dye Reactive Black 5 compared to the non bacterized controls.

Abstract
A method for evaluating the potential of reuse of biomasses for economic purposes is here presented starting from a case study. Juncus acutus plants and rhizospheres were harvested from abandoned Zn-Pb mine areas of southwest Sardinia (Italy). Thermogravimetry and Differential Thermal analyses were performed to evaluate the temperatures at which significant reactions occur. X-ray Diffraction (XRD) analysis was carried out on raw samples and on samples heated ex-situ (by a conventional diffractometer) or in-situ (by synchrotron-based diffraction). Raw samples mainly consist of quartz, phyllosilicates, and feldspars with minor amounts of sulfides, sulfates, and Fe, Pb, and Zn carbonates, concentrated in the rhizosphere. After heating, Zn and Fe oxides and willemite are observed in internal roots and stems, revealing the presence of these metals in the plant tissues. In-situ heating was less effective than ex-situ in revealing minor phases in organic samples, probably because the scarcity of oxygen within the sample holder did not allow the degradation of organic compounds and the oxidation of sulfides, resulting in a low quality XRD signal even if obtained with the high resolution ensured by a synchrotron light source. This method can be applied to plants from polluted sites for metal exploitation, and/or to biomasses from unpolluted sites for biochar production, since both applications take advantage of the knowledge of the minerals formed after heating.

Abstract
Juncus acutus, an halophite plant pioneer in extremely polluted mine areas, was harvested in three different locations of Sardinia (Italy), having Zn soil concentration up to 80g/kg, and Zn water concentration ranging between 10-3g/L and 10-1g/L. Rhizosphere and plant samples were investigated combining X-ray microscopy (XM)/spectroscopy (XAFS) and infrared microspectroscopy (FTIR) to elucidate the chemical composition, (bio)mineralogy and Zn coordinative environment. The multi-technique approach allowed recognizing different biomineralization processes, and Zn complexes in the plant tissues. The Zn chemical environment in root biominerals is multi-phase and, depending on the sampling site, can comprise amorphous Zn silicate, Zn apatite, hydrozincite, and Zn sulphate. Zn cysteine and Zn histidine, complexes quoted as part of a detoxification strategy, were found mainly in plants from the site where the Zn water concentration has the highest values. This different site-specific mode of Zn biomineralization has relevant implications for phytoremediation techniques and for further biotechnology development, which can be better designed and developed after knowledge of site-specific-molecular processes ruling mineral evolution and biomineralization. Carboxylic groups and organic compounds (lignin, cellulose, hemicellulose, pectin and esters) were identified by FTIR analysis, thought the Zn speciation is not apparently linked to these carboxylic group rich biopolymers.

Abstract
In the present study, a full scale horizontal subsurface flow constructed wetland was designed, constructed and operated to treat domestic wastewater of Kızılcaören village in Samsun city of Turkey. The total surface area of HSFCW was divided into equal parts. The effects of Juncus acutus L. and Cortaderia selloana (Schult.Schult.f.)Asch.&Graebn. on pollutants removal in HSFCWs were evaluated with the meteorological factors. The average removal efficiencies of J. acutus and C. selloana were determined as 60.3-57.7% for BOD; 24.2-38.9% for TN; 31.4-49.8% for OM; 35.4-43.3% for TP; 18.9-27.1% for orthophosphate; 24.4-28.7% for NH4-N; 29.5-37.2% for TSS; and 35.3-44.3% for TSM. Two-way ANOVA was applied to determine any difference for the removal of all parameters between the plant types and months on the mean values of contaminant removal. A correlation matrix of all parameters was determined. Subsurface flow constructed wetland was found quite efficient for the treatment of domestic wastewater in rural settlements. HSFCW is also more economical to install and maintain than a conventional wastewater treatment system while enhancing ecosystem services.

Abstract
A phytoremediation pilot emulating a shallow aquifer planted with Juncus acutus showed to be effective for remediating Bisphenol-A (BPA) contaminated groundwater. Biostimulation with root exudates, low molecular weight organic acids, of J. acutus did not improve BPA-degradation rates. Furthermore, the endophytic bacterial community of J. acutus was isolated and characterized. Many strains were found to possess increased tolerance to metals such as Zn, Ni, Pb and Cd. Moreover, several endophytic bacterial strains tolerated and even used BPA and/or two antibiotics (ciprofloxacin and sulfamethoxazole) as a sole carbon source. Our results demonstrate that the cultivable bacterial endophytic community of J. acutus is able to use organic contaminants as carbon sources, tolerates metals and is equipped with plant-growth promoting traits. Therefore, J. acutus has potential to be exploited in constructed wetlands when co-contamination is one of the restricting factors.

Abstract
In their natural habitats, different mechanisms may contribute to the tolerance of halophytes to high soil salinity and other abiotic stresses, but their relative contribution and ecological relevance, for a given species, remain largely unknown. We studied the responses to changing environmental conditions of five halophytes (Sarcocornia fruticosa, Inula crithmoides, Plantago crassifolia, Juncus maritimus and J. acutus) in a Mediterranean salt marsh, from summer 2009 to autumn 2010. A principal component analysis was used to correlate soil and climatic data with changes in the plants' contents of chemical markers associated with stress responses: ions, osmolytes, malondialdehyde (MDA, a marker of oxidative stress) and antioxidant systems. Stress tolerance in S. fruticosa, I. crithmoides and P. crassifolia (all succulent dicots) seemed to depend mostly on the transport of ions to aerial parts and the biosynthesis of specific osmolytes, whereas both Juncus species (monocots) were able to avoid accumulation of toxic ions, maintaining relatively high K(+)/Na(+) ratios. For the most salt-tolerant taxa (S. fruticosa and I. crithmoides), seasonal variations of Na(+), Cl(-), K(+) and glycine betaine, their major osmolyte, did not correlate with environmental parameters associated with salt or water stress, suggesting that their tolerance mechanisms are constitutive and relatively independent of external conditions, although they could be mediated by changes in the subcellular compartmentalization of ions and compatible osmolytes. Proline levels were too low in all the species to possibly have any effect on osmotic adjustment. However-except for P. crassifolia-proline may play a role in stress tolerance based on its 'osmoprotectant' functions. No correlation was observed between the degree of environmental stress and the levels of MDA or enzymatic and non-enzymatic antioxidants, indicating that the investigated halophytes are not subjected to oxidative stress under natural conditions and do not, therefore, need to activate antioxidant defence mechanisms.
