Research Activities

1)Microbial degradation studies on agro-industrial Chemicals:

����� For the past one decade we do screen and isolate the microbes (Bioremediation strains) degrading agro-industrial chemicals � working on biochemical and molecular level of bioremediation strains � also maintaining bioremediation strain stocks - analyzing the related enzymes and metabolites to elucidate pathways in degradation of�� biodegradable agro-industrial chemicals. We are using PCBSas a viable compound in active biodegradation.

2)Immunochemical research on agrochemicals:

����� We raise polyclonal/monoclonal antibodies against agro-industrial chemicals. And the responsible antibodies are used to detect the respective xenobiotic contamination in percolated ground water, agricultural�� run off, vegetables and fruits. We have developed antibodies to hapten bound endosulfan, fenitrothion, monocrotophos etc.

3)Medicinal plants active principle identification research:

����� This study involves purification of antimicrobial compounds from Ethno pharmacologically significant plants of both terrestrial and marine source, structural characterization and determination of mode of action of active principle against selected pathogenic microbes by proteomic approach and virtual in silico analysis of antimicrobial leads to the target proteins.

4)Molecular and biochemical study on Urolithiasis

����� This study involves induction of urolithiasis in animal models, study of metabolic factors involved in urolithiasis, screening the level of calcium oxalate in different food materials and study their effect on urolithiasis; screening the medicinal plants having lithotryptic effects and to isolate calcium oxalate degrading microorganisms and study their therapeutic role in urolithiasis.

5) Testing the efficiency and uncertainty of sample processing for analysis of food contaminants in human food

b) Forthcoming Projects

����� Nanocrystal-Based detection of mutations in Primary Hyperoxaluria Type 1

Primary Hyperoxaluria Type 1 is an autosomal recessive disorder caused by the defect in liver specific peroxisomal enzyme alanine:glyoxylate aminotransferase (AGT). The mutations and polymorphisms in AGXT gene causes mistargeting of AGT to mitochondria instead of the normal location-peroxisomes leading to overproduction of oxalate and glycolate in urine and blood resulting in kidney stones and renal disorder. When untreated leads to systemic oxalosis and death. Herein, we demonstrate how inorganic nanocrystal tags can lead to distinct bioelectronic signatures for unknown individual SNPs as well as for known two-base mutations in a single DNA target. The high performance of electrochemical devices, their inherent miniaturization, and their low cost and power requirements make them excellent candidates for decentralized DNA diagnostics.
