Among toxic heavy metals, cadmium is one of the most dangerous for human health. Since cadmium is a well-known toxic metal, industrial effluents and wastewaters rich in cadmium must be treated prior to their disposal. Present study deals with the evaluation of biosorptive removal of cadmium by Trichoderma fungus. The effect of different important parameters such as initial pH, cadmium concentration, contact time, stirring rate, and temperature on cadmium sorption was investigated. Cadmium biosorption capacity and its removal efficiency increased along with the increase of pH of the solution, and maximum biosorption of cadmium(II) ions were observed at pH 6. Biosorption kinetics data were fitted using pseudo-first-order and pseudo-second-order models. It was found that the kinetics data fitted well the pseudo-first-order during the initial 120 min of biosorption, and when the biosorption time was 120 min, the experimental data fitted very well with the pseudosecond-order kinetics reaction. Thermodynamic parameters such as standard Gibbs free energy (ΔG˚), standard enthalpy (ΔH˚), and standard entropy (ΔS˚) were evaluated. The results confirmed that biosorption of cadmium(II) ions by Trichoderma fungus was spontaneous and endothermic nature.

“…ROS can oxidize proteins, lipids, and nucleic acids, often leading to alterations in cell structure and mutagenesis (Scandalios, 2005). Chakraborty et al (2014) indicated that cadmium accumulation could induce oxidative stress characterized by H 2 O 2 /O 2 -production, lipid peroxidation and protein oxidation. Heavy metals cause oxidative damage to plants either directly or indirectly through the formation of ROS, which cause further severe oxidative damage to different cell organelles and biomolecules (Nagajyoti et al, 2010).…”

The effects of different concentrations (10, 50, 100 and 500 μM) of cadmium (Cd) on manganese (Mn) and iron (Fe), lipid peroxidation, activities of antioxidant enzymes and photosynthetic function were investigated in hydroponically grown cucumber (Cucumis sativus L.). Results indicated that cadmium was accumulated primarily in roots. In the roots and shoots, the cadmium content increased with the increasing cadmium concentrations, and induced decrease of manganese significantly (P < 0.005). The levels of iron had an increasing trend with increasing cadmium concentration and duration of treatment. Cadmium-induced oxidation stress and lipid peroxidation in C. sativus showed by the increased concentration of MDA (malondialdehyde). Cadmium induced higher SOD (superoxide dismutase) and POD (peroxidase) activities than CAT (catalase) activity, suggesting that SOD and POD provided a better defence mechanism against cadmium-induced oxidative damage in C. sativus. The net photosynthetic rate, transpiration rate, stomatal conductance and intercellular CO 2 concentration were reduced in the presence of cadmium.

“…Because of the long-term selection effects of the environment, Cd-resistant fungi with strong Cd adsorption capacity may exist in a Cd-polluted environment. Fungi with high Cd resistance and Cd adsorption capacity that have been screened from wastewater and soil in industrial and mining areas at home and abroad include aspergillus foetidus [17], penicillium, and yeast [18], but only a few have been screened from paddy soil. Local Cd-resistant microorganisms with high adsorption capacities for heavy metals can better adapt to the special environment of heavy metal-polluted paddy soil [19], so as to play a role in biological adsorption.…”
