Sulphur protects mustard ( Brassica campestris L.) from cadmium toxicity by improving leaf ascorbate and glutathione

Abstract: In a pot-soil culture ameliorative effect of sulphur (S) (0 or 40 mg S kg−1 soil) on cadmium (Cd) (0, 25, 50 and 100 mg Cd kg−1 soil)-induced growth inhibition and oxidative stress in mustard (Brassica campestris L) cultivar Pusa Gold was studied Cadmium at 100 mg kg−1 soil caused maximum increase in the contents of Cd and thiobarbituric acid reactive substances (TBARS) in leaves Maximum reductions in growth (plant dry mass, leaf area), chlorophyll content, net photosynthetic rate (PN) and the contents of ascorbate (AsA), glutathione (GSH) were observed with 100 mg Cd kg−1 soil compared to control The application of S helped in reducing Cd toxicity, which was greater for 25 and 50 mg Cd kg−1 soil) compared to 100 mg Cd kg−1 soil Addition of S to Cd-treated plants showed decrease in Cd and TBARS content in leaves and restoration of growth and photosynthesis through increase in the contents of AsA and GSH Net photosynthetic rate and plant dry mass were strongly and positively correlated with the contents of AsA and GSH It is suggested that S may ameliorate Cd toxicity and protects growth and photosynthesis of mustard involving AsA and GSH

Applications of Redox Mediators in the Treatment of Organic Pollutants by Using Oxidoreductive Enzymes: A Review

Abstract: An enzymatic approach has attracted much interest in the remediation/degradation of various organic pollutants present in the wastewater coming out of industries. The treatment of several pollutants sometimes causes problems due to the recalcitrant nature of the compounds. However, these recalcitrant compounds were degraded/transformed by enzymes in the presence of certain redox mediators. These redox mediators enhanced the range of substrates and efficiency of degradation of the recalcitrant compounds by severalfold. Enzymes whose potential has been exploited for this purpose are laccases, lignin peroxidases, manganese peroxidases, horseradish peroxidases, turnip peroxidases, bitter gourd peroxidases, and others. Several redox mediators have been reported in the literature but very few of them are frequently used, for example, 1-hydroxybenzotriazole, veratryl alcohol, violuric acid, 2-methoxy-phenothiazone, 3-hydroxyanthranilic acid, anthraquinone 2,6-disulfonic acid, 2,2-azino-bis(3-ethylbenzothiazoline...
