Mycorrhiza assisted approach for bioremediation with special reference to biosorption
(EM International, 2017) Shweta Pathak; Prasann Kumar; Pankaj Kumar Mishra; Mukul Kumar
Plants rising in metal polluted soils anchorage a significant group of microorganism that are capable of tolerating high concentration of metal and giving a number of benefits to both the soil and the plant of concern. In our study related to the microbes assisted remediation approaches we find that, among the microorganism involved phytoremediation of heavy metal, the rhizosphere fungus deserve special attention because they can directly improve the phytoremediation process by changing the metal bioavailability through altering the soil pH, release of chelators (Organic acid and siderophores), oxidation/reduction reaction. Similarly the metal tolerant mycorrhizal fungi have been frequently reported in hyper-accumulators growing in metal polluted soils indicating that these fungi have evolved a heavy metal-tolerance and that they may play important role in phytoremediation of the site.

Role of secondary metabolites for the mitigation of cadmium toxicity in sorghum grown under mycorrhizal inoculated hazardous waste site
(Springer Singapore, 2018) Prasann Kumar; Shweta Pathak; Mukul Kumar; Padmanabh Dwivedi
Apart from the many primary metabolites like carbohydrate, proteins, fats, and hormones, a number of organic compounds in plants are not synthesized in the principle stream, but they are most important for the plant functions. These compounds are secondary metabolites broadly classified in terpenes, alkaloids, and phenols. Nowadays, heavy metal contamination is the greatest concern worldwide. The role of secondary metabolites is well acquainted with facts that it imparts the significant effect in the mitigation of heavy metal toxicity in the plants. The FTIR data of the experiments indicate clearly that phenols, aldehyde, and ketones will play the critical role in the regulation of heavy metal toxicity in plants. © Springer Nature Singapore Pte Ltd. 2018.
