Dr. Umesh C. Naik is Assistant Professor at the Department of Botany. He has more than 7 years of teaching and research experiences. He completed his PhD degree on Environmental Microbiology at Jawaharlal Nehru University, New Delhi in 2013. Dr. Naik has worked on development of sequential treatment system of using activated charcoal and  metal resistant bacteria strain for the detoxification of electroplating effluent using advanced analytical techniques. His current research focuses on the uptake mechanism of oxyanions by metal resistant microbes and development of antimicrobial compounds against pathogenic strains.

Detoxification of AMD through Enterobacter sp. AMD01-bead and algal bioreactor

The removal efficiency of integrated bacteria-algal system with immobilized SRB beads and algal tank was found to be higher in comparison to batch culture. Comparative reduction rate between bacteria-algal and batch processes has revealed that efficiency of immobilized SRB-beads system was maximum. The integrated bacteria-algal treatment system efficiently removed approximately 95-99% of toxic metals in AMD as compared to batch process. Further bacteria-algal system increases the DO level in treated water.

 

Study on sulphate transporters of Enterobacter sp. AMD01 under aerobic and anaerobic conditions

Reduction of toxic metals by SRB is directly related to the uptake mechanism of oxyanions through sulphate transporters. To deal with the effective and proper management of the bioremediation process, there is a need to understand the membrane transporters and its uptake efficiency. Our project focuses on structural parameters such as  the transmembrane helices (TMH), amphipathic helix (AH), and the propensity of membrane protein for understanding the uptake  mechanisms in two different conditions.

 

Developing green based nanoparticles for antimycobacterial activity

Another part of our research areas is the green based synthesis of metallic and alloy nanoparticles using plant extracts and microorganisms. The functionalized bio-nanocomposites are meant to be used as antibacterial agents. Different biological compounds are being used as coating and stabilizing agents for sustainable and targeted drug delivery and to improve the drug efficacy.
