Constructed wetland systems vegetated with different plants applied to the treatment of tannery wastewater.
TLDR
Despite the high removal of organic content from the influent wastewater, during 17 months of operation, no significant differences in performance were observed between units. Expand
Phytoremediation of polyaromatic hydrocarbons, anilines and phenols
TLDR
Plant and microbial degradative capacities, viewed as a continuum, have been dissected in order to identify where bottlenecks and limitations exist and to prevent their movement into wildlife food chains. Expand
Metal uptake by microalgae: Underlying mechanisms and practical applications
TLDR
Self‐defense mechanisms developed by microalgal cells to survive in metal‐containing media and environmental factors that affect their removal are reviewed here in a comprehensive way and further discussed in attempts to rationalize this form of remediation vis‐a‐vis with conventional nonbiological alternatives. Expand
Evaluation of Phenolic Profiles and Antioxidant Activities of Turkish Medicinal Plants: Tiliaargentea, Crataegi Folium Leaves and Polygonum bistorta Roots
There is a growing interest in the food industry and in preventive health care for the development and evaluation of natural antioxidants from medicinal plant materials. In the present work, extracts… Expand
Remediation of Heavy Metal Contaminated Soils: Phytoremediation as a Potentially Promising Clean-Up Technology
TLDR
To enhance phytoremediation as a viable strategy, microbiota from the rhizosphere can play an important role, but the use of genetic engineering can also increase the success of the technique. Expand
Valorisation of natural extracts from marine source focused on marine by-products: A review
TLDR
This review updates information on this issue and conveys critical analysis of the chief methodologies to carry out extraction, purification and eventual transformation, with a focus on their actual and potential applications. Expand
Biosorption of zinc ions from aqueous solution by the microalga Scenedesmus obliquus
Aquatic environments are often exposed to toxic heavy metals, which gain access to the food chain via microalgae and may cause severe problems at higher trophic levels. However, such a metabolic… Expand
Use of constructed wetland systems with Arundo and Sarcocornia for polishing high salinity tannery wastewater.
TLDR
CW systems planted with salt tolerant plant species are a promising solution for polishing saline secondary effluent from the tannery industry to levels fulfilling the discharge standards. Expand
Toxicity of cadmium and zinc on two microalgae, Scenedesmus obliquus and Desmodesmus pleiomorphus, from Northern Portugal
TLDR
Aquatic environments often contain toxic heavy metals that may enter the food web via uptake by microalgae and eventually cause severe poisoning problems at higher trophic levels and one observed that S. obliquus can tolerate higher Zn concentrations than D. pleiomorphus, but the reverse holds regarding exposure to Cd. Expand
Phosphate-solubilizing rhizobacteria enhance Zea mays growth in agricultural P-deficient soils
TLDR
It is clearly indicates that inoculated PSB have great potential to be used as biofertilizers in P-deficient soils, especially strains Pseudomonas sp. Expand
