PROJECT TITLE- Regulation of expression of hPLSCR1, hPLSCR2 and hPLSCR4 human scramblase genes by Sox5 transcription factor

The human plasma membrane contains specific proteins called Human phospholipid scramblases (hPLSCRs). There are four homologes of scamblase, hPLSCR1-hPLSCR4. Except for Snail and c-Myc, no other transcription factor (TF) has been reported to regulate the expression of hPLSCRs. So, here, we are trying to study the transcriptional regulation of hPLSCRs by another TF, Sox5. Sox5 TF is a protein of the SOX (SRY- related HMG box) family involved in embryonic development and determines the fate of a cell.

PROJECT TITLE- “Production and Application of Microbial Mutanase for Prevention and Reduction of Dental Plaques

SUMMARY- Mutanases (1-3α-glucanases) has potential for inhibiting dental plaqueformation by suppressing the formation of mutanby promoting the degradation of mutan into low-molecular-weight glucans. In the present study mutan( mixed linkage of α-1-3 and α-1-6) was synthesized from Streptococcus mutans and characterization studies were conducted. The mutanwill be used as a substrate in the production of enzyme mutanase from microorganisms. Invitro studies will be conducted to study the rate of hydrolysis of mixed biofilms (carcinogenic streptococcus strains) by using mutanase enzyme.

Biochemical characterization of phospholipid scramblase 1 (SCRM-1) from Caenorhabditis elegans

PL scramblases are a family of protein present in eukaryotes which mediate bidirectional PL translocation. PL scramblases from several different organisms have been characterized so far. Genome of C elegans possess eight PL scramblases, scramblase 1 through 8. SCRM-1 of C. elegans shows 41% sequence identity with human PL scramblase 1 (hPLSCR1). Sequence alignment revealed that all the functional domains of hPLSCR1 are also present in SCRM-1. In the current study we are aiming to functionally characterize SCRM-1 through biophysical and biochemical approaches.

Project Title:Evaluation of Pseudomonas sp. in coffee wastewater treatment and understanding the enzymology of caffeine degradation.

Summary:Pseudomonas sp. isolated from soil of the coffee plantation area showed excellent caffeine degradation capability. Genomic sequencing of Pseudomonas sp., revealed presence of 5 genes, ndmA, ndmB, ndmC, ndmD and ndmE, which are involved in caffeine degradation. Currently, we are evaluating its potential to devise a complete coffee wastewater treatment strategy. In addition, we are also characterizing the genes involved in caffeine degradation for its application in food industries.

Project Title: Numerical Investigations on Enhanced Crude Oil Recovery by Microbial Flooding Within a Sandstone Formation

Summary: Our research is focused on developing conceptual, mathematical and numerical models to comprehensively study the influences of crucial physical, chemical, biological, environmental and operational parameters on in-Situ Microbial Enhanced Oil Recovery (MEOR) within sandstone oil field, and to devise optimization strategies for improving accountability and efficiency of MEOR. The developed models with relatively lower computational cost and running time are expected to improve the predictive capability to pre-select potential field candidates for successful MEOR implementation.

Project Title: Biochemical characterization of an esterase from Clostridium acetobutylicum with novel GYSMG pentapeptide motif at the catalytic domain and significance of conserved motif

Summary:Clostridium acetobutylicum (ATCC 824) is an industrially important solventogenic microbe for the production of acetone, butanol and ethanol. Gene CA_0816 encodes esterases. This gene was overexpressed in E. coli strain BL21and purified using Ni 2+ -NTA affinity chromatography. Sequence analysis predicts that Ca-Est predicts the presence of catalytic amino acids Ser 89, His 224 and Glu 196. presence of novel GYSMG conserved sequence (instead of GDSAG and GTSAG motif) and undescribed variation of HGSG motif of microbial HSL. Significance of this variant conserved motif has to be studied experimentally.

Project Title:Characterisation of NdmA component of methylxanthine oxygenase system in Pseudomonas sp. NCIM 5235 and whole cell applications for treatment of industrial coffee wastewater

Summary:The caffeine degrading bacteria Pseudomonas sp. NCIM 5235 utilizes caffeine as sole growth substrate by metabolizing caffeine via N-demethylation (Ndm). This process involves various components out of which we will carry out biochemical characterization of NdmA component (monooxygenase). We plan to optimize Pseudomonas sp. NCIM 5235 for pilot-scale coffee wastewater treatment by studying its interaction with other microbes in the wastewater. Also, we will analyse cells immobilized with compatible nanoparticles for its efficacy in treatment of industrial coffee wastewater.
