Major Research Accomplishments
- Surface Plasmon Resonance (SPR) method for the detection of Listeria monocytogenes was optimized using Wheat germ agglutinin (WGA) lectin with a detection sensitivity of 3.0 log cfu/ 100µl in buffer and milk system, respectively.
- Developed SPR has shown minimum false positive and negative reaction with other G+Ve and G-ve bacteria with the detection time of around 20-30 min, respectively.
- Protocol for synthesis of Polyaniline-pectin conducting polymer particles was optimized and the particles were characterized using FT-IT and particle size analyser using Zeta-size analyser
- A paper strip based assay has been developed using PANI-PEC particles immobilized paper strips for the detection of coli and coliform in milk using newly developed ECS medium and CSM, respectively with the a detection limit of 0.5 log cfu/100 µl within a time period of 10 ½ hrs
- A paper strip based assay has been developed using PANI-PEC particles immobilized paper strips for the detection of total microbial load in milk in milk using newly optimized medium with a detection sensitivity in the range of 0.5 to 8.5 log cfu/ 100ul and with a detection of time of 5-6 hrs using newly optimized broth medium.
- Surveillance of antibiotic resistance coli in milk supply chain was undertaken in our lab and E.coli isolates have shown resistance towards cefepime, gentamicin, erythromycin, trimethoprim, chloramphenicol, ciprofloxacin, tetracycline and 4 among these isolates have shown resistance to ESBL antibiotics (harboring the CTX-M gene).
- Protocol for the synthesis of magnetic molecularly imprinted polymers based on iron magnetite encapsulated polymer of methacrylate (monomer) and ethylene-glycol-dimethacrylate (monomer-cross-linker) for selective extraction of captan pesticide from natural sample.
