13. Initial Growth of Eremanthus incanus (Less.) Less in Soil with Manganese
ABSTRACT The objective of this study was to evaluate the initial growth of Eremanthus incanus (Less.) Less (candeia) in soil with manganese doses. Additionally, it sought to assess manganese concentration, and accumulation in the organs of the plant as well as quantify the appropriate concentration of this element in the soil. The experiment was installed i

14. IN VITRO PHYTOREMEDIATION OF PERSISTENT ORGANIC POLLUTANTS BY Helianthus annuus L. PLANTS
Plant model systems are needed to properly conduct basic laboratory studies prior to field applications of phytoremediation. In vitro plant cultures are a useful tool for such research. This study focuses on the removal and/or degradation of 24 persistent organic pollutants under in vitro conditions by Helianthus annuus L (sunflower). The main purpose of exp

15. Potentiality of Melastoma malabathricum as Phytoremediators of soil contaminated with sewage sludge
ABSTRACT: Heavy metal pollution of the soil environment has become a major source of concern and continues to pose serious health problems to both humans and ecological systems worldwide. Phytoremediation is a biological treatment whereby plants are used to remove pollutant from the environment. An experiment was conducted to evaluate the potential of Melast

16. Role of glutathione in tolerance to arsenite in Salvinia molesta, an aquatic fern
ABSTRACT In many plant species, tolerance to toxic metals is highly dependent on glutathione, an essential metabolite for cellular detoxification. We evaluated the responses of glutathione metabolism to arsenite (AsIII) in Salvinia molesta, an aquatic fern that has unexplored phytoremediation potential. Plants were exposed to different AsIII concentrations i

17. SODIUM PHYTOREMEDIATION BY GREEN MANURE GROWING IN SOIL IRRIGATED WITH WASTEWATER OF DAIRY INDUSTRY
ABSTRACT: Phytoremediation is a technique that uses plants to decontaminate soils containing harmful organic and inorganic elements. The aim of this study was to evaluate the potential of three species of forage green manure in phytoremediation of saline soil irrigated with treated effluent from dairy processing plant. The design used was randomized blocks (

18. Rhizospheric activity of phytoremediation species in soil contaminated with picloram1
RESUMO Atividade rizosférica de espécies fitorremediadoras em solo contaminado com picloram Algumas espécies de planta têm a capacidade de estimular a atividade da microbiota na rizosfera e, com isso, aumentar a degradação de herbicida no solo. Objetivou-se avaliar a atividade microbiana de solos contaminados com picloram e pré-cultivados com espécie

19. Microbial activity of soil with sulfentrazone associated with phytoremediator species and inoculation with a bacterial consortium
ABSTRACT Phytostimulation plays a key role in the process of rhizodegradation of herbicides in soil. Additionally, bio-enhancement associated with phytoremediation may increase the efficiency of the decontamination process of soils with herbicides. Therefore, the objective of this study was to evaluate the biomass and microbial activity of soil contaminated

20. Phytoremediation of arsenic-contaminated water: the role of antioxidant metabolism of Azolla caroliniana Willd. (Salviniales)
ABSTRACT Phytoremediation has proven to be an efficient technology for removing arsenic (As) from water, but the plants used in this process need to be tolerant to the damage caused by As. The toxic effect of As on growth and functioning of the antioxidant system was studied in individual plants of Azolla caroliniana exposed to five concentrations of As (0.0

21. Phytoextractor Potential of Cultivated Species in Industrial Area Contaminated by Lead
ABSTRACT: High growth rate is one of the criteria used for the selection of species to be used in metal phytoextraction programs. This study was carried out to characterize the growth characteristics of sunflower (Helianthus annuus L.), castor bean (Ricinus communis L.), corn (Zea mays L), and vetiver [Vetiveria zizanioides (L.) Nash] grown on a soil contami

22. Biological properties of Endophytic Fungi
The endophytic fungus is have rich source of secondary metabolites which act as biological active agent in the higher plants. The fungal derivatives play vital part in human life and their compounds are the source of drug for cancer, microbial and viral diseases. The natural compounds from the endophytes acts as growth inhibitor of plant pathogenic organism.

23. Behavior of Eucalyptus urophylla and Eucalyptus citriodora Seedlings Grown in Soil Contaminated by Arsenate
ABSTRACT Persistent areas of tailings and deposits from coal and gold mining may present high levels of arsenic (As), mainly in the arsenate form, endangering the environment and human health. The establishment of vegetation cover is a key step to reclaiming these environments. Thus, this study aimed to evaluate the potential of Eucalyptus urophylla and E. c

24. Bioremediation of polyaromatic hydrocarbons (PAHs) using rhizosphere technology
The remediation of polluted sites has become a priority for society because of increase in quality of life standards and the awareness of environmental issues. Over the past few decades there has been avid interest in developing in situ strategies for remediation of environmental contaminants, because of the high economic cost of physicochemical strategies,
