The Investigation of the Impact of Toxicity of Metals on Oxygen-Evolving Complex in .

The current article reported the investigation of metal toxicity on the oxygen-evolving complex (OEC) in Spinacia oleracea related to depletion in chloride ion concentration, an essential part of the photosystem (II). The greenhouse experiment was conducted where was cultivated in three replicates with control plants (plants "a") treated with tap water. Moreover, 30 ppm of Cu ion solution and Pb ion solution was used to irrigate the rest of the plants, labeled as plants "b" and "c", respectively, on alternative days.

Advanced catalytic oxidation process based on a Ti-permanganate (Mn/Ti-H) reaction for the treatment of dye wastewater.

This article discusses the titanium (Ti)-based permanganate advanced catalytic oxidation process (ACOP) for the possible recovery of thousands of tons of dye wastewater. The heterogeneous catalyst TiO in the solid state employed in the liquid phase reaction mixture with dye and potassium permanganate was recovered and reused several times for reproducible results. The kinetics were examined at various operational parameters like the effect of dyes, the effect of oxidants, the amount of catalysts, and the effect of acids, temperature, and various organic and inorganic additives used in the textile industry.

The insects as an assessment tool of ecotoxicology associated with metal toxic plants.

In this article, the assessment of lethal effects of Copper (Cu) on Luffa acutangula and Spinacia oleracea plants investigated in relation to the presence of insect species Oxycarenus hyalinipennis. The analysis of Cu-treated plants displays the information of rapid growth of Oxycarenus hyalinipennis species in triplicate. However, results showed that the impact of metal toxicity appeared as the reduced growth rate of plants, and dense growth of the insect species Oxycarenus halinipennis followed by the chewing/degradation of the toxic plant.

New Prospective for Enhancement in Bioenergy Resources Through Fungal Engineering.

Background: Lignin and cellulose, organic constituents of the plant or plant-based material not commonly used for feeding purpose are referred as Biomass. Patents suggest that this can be used as the best resource of renewable energy. Vesicular Arbuscular Mycorrhizae (VAM) fungi can play an effective role in biomass manufacturing through activated metabolism of the plant under dual symbiosis.

Remediation of Cu metal-induced accelerated Fenton reaction by potato peels bio-sorbent.

This article has allied exposure to Ecological Particulate Matter (EPM) and its remediation using potato peel surface (PPC) bio-sorbent on two important edible crops Spinacia oleracea and Luffa acutangula. Fenton reaction acceleration was one of the major stress oxidation reactions as a consequence of iron and copper toxicity, which involve in the formation of hydroxyl radical (OH) through EPM. Results showed that the oxidative stress encouraged by Cu in both species that recruits the degradation of photosynthetic pigments, initiating decline in growth, reduced leaf area and degrade proteins.

Glomus fasciculatum Fungi as a Bio-convertor and Bio-activator of Inorganic and Organic P in Dual Symbiosis.

Background: Dual symbiosis played an effective role in drought condition and temperature. Furthermore, performed services in absorption of water and solubilization of chief nutrients specially phosphorus for growth of plants. Phosphorous is essential for plant growth in any climatic condition because of central constituent of ATP providing chemical energy for all metabolic reactions of plants.
