Cover Letter:
Dear,
I am Abarnadevi S, and I recently completed my master’s degree in Biotechnology from Bharathidasan University, Tamil Nadu, India. Through my academic journey, I have a strong passion for research, particularly in microbiology, molecular biology, and environmental science.
During my bachelor’s project at CSIR-Central Leather Research Institute, Chennai, I worked on “Recent Advances in the Application of Extracted Extracellular Polymers from Different Microorganisms as Nanocomplexes in the Removal of Chromium.” My research focused on extracting extracellular polymeric substances (EPS) from microorganisms like bacteria, fungi, yeast, and algae, which I isolated from soil near tannery effluent discharge sites from CLRI, chennai. These EPS were biochemically characterized for their carbohydrate, protein, and lipid content. I then synthesized nanocomplexes using EPS as reducing agents and optimized parameters such as time, temperature, and concentration for chromium removal. The results show that EPS-based nanocomposites exhibited significantly higher chromium adsorption rates compared to free EPS. This project deepened my interest in microbiology and its applications in environmental remediation.
For my master’s project at the ICAR- Central Island Agriculture Research Institute, Andaman and Nicobar Islands, project titled “Prevalence of Antimicrobial-Resistant E. coli, Salmonella, and Klebsiellapneumoniae in Chicken Retail Shops of Port Blair.”I collected samples from six different chicken retail shops across the islands, including meat, chopping boards, knives, and cleaning water. From 50 chicken swab samples, I isolated 43 strains of Enterobacteriaceae. Among these, E. coli, Salmonella, and K. pneumoniae were found to be most prevalent in meat samples compared to other sources. I conducted antibiotic resistance profiling for these bacteria against 12 commonly used antibiotics. The highest resistance was observed against Erythromycin (93.02%), Amoxyclav (93.02%), Ampicillin/Cloxacillin (86.04%), Ciprofloxacin (76.74%), and Oxytetracycline (74.41%). Conversely, the lowest resistance was recorded for Co-Trimoxazole (41.86%), Chloramphenicol (30.23%), Gentamicin (34.88%), and Amikacin (13.95%). Then I performed biochemical characterization to assess enzyme activity and identified the presence of ESBL and AmpC enzymes, which contribute to antimicrobial resistance. The results revealed that ESBL activity was higher than AmpC activity, with E. coli showing the highest prevalence (75%), followed by Salmonella (63%) and K. pneumoniae (47%). I validated these findings using RT-PCR for confirmation.
During my recent three-month internship at Mushloop Private Limited, Salem, I worked on developing fungal-based packaging materials, bio plastics, and the extraction of natural pigments. My responsibilities included purifying and inoculating fungal cultures, as well as optimizing growth conditions within substrate bags to enhance the production of eco-friendly packaging and pigments (Pycnoporus) supplied to the textile industry. I have experience in grain spawn inoculation, mycelium moulding within substrate bags, and the production of bio plastics (chitin) derived from mycelium. Additionally, I developed skills in pigment extraction using Soxhlet and distillation methods, cultivated fungal fruiting bodies, and prepared substrate bags for both pigment and material production.
My technical skill includes Extraction of pigments-using Soxhlet apparatus and solvent-based techniques, Pigment Purification – Purifying extracted pigments through vacuum filtration and distillation processes, Fungal Pigment Production – Generating pigments from fungi through both submerged and solid-state fermentation methods, Mycelium-Based Mould Fabrication – Designing and cultivating moulds using mycelium as a sustainable material.
My projects and studies have helped me gain a strong understanding of microbiology, molecular biology, biochemistry, environmental science, and nanotechnology. I have developed skills in analyzing microbes, growing cultures, synthesizing nanoparticles from microorganisms, plants, and chemicals, and conducting biochemical tests. Since both of my projects focus on environmental and societal issues, my ultimate goal is to improve people’s lives through meaningful research.
I am particularly excited about the opportunity to join Unicor Pharmatech and contribute to its groundbreaking research initiatives. I am confident that my skills and dedication would make me a meaningful impact on your team. I would be grateful for the chance to discuss how I can contribute to your vision and am available at your earliest convenience.
Thank you for considering my application.
Sincerely,
Abarna Devi S
