Welcome to the Department of Microbiology in the School of Life Sciences! Microorganisms are invisible entities yet they are an indispensable part of the human body and the environment. Some of them are our friends whereas others are our foes. Microorganisms play a pivotal role in governing the existence of all other forms of life on earth and in their absence eventually life would get extinguished. A deeper understanding of this invisible world of microbes would foster practical approaches towards maintaining healthy ecosystems as well as promoting the health of all other forms of life. Our faculty members are actively engaged in imparting not only the theoretical knowledge but also a practical understanding of the subject both at the undergraduate and the postgraduate level. Apart from the normal class activities the students are involved in research work and projects where they get an opportunity to tap their experimental skills and abilities. We strongly believe that our students have a strong potential to make significant contributions in the field of scientific research, academia as well as professional organizations.

The primary focus of Prof. Pal’s research is studying bioremediation of heavy metal toxicity by microorganisms, and elucidating the molecular mechanisms of heavy metal toxicity (e.g. Antimony) resistance in several plant bodies. Specifically, he studies the genetic makeup and molecular pathways involved in heavy metal resistant bacteria by identifying the responsible genes and the genetic evolution of these genes. Alongside, he is investigating the role of selection pressure on the evolution of the heavy metal resistance in bacteria. The goal of this research is to discover the heavy metal toxicity resistant bacteria mediated protective mechanisms of plants and the evolution of these resistant bacteria.

The Pal lab is also analyzing the formulation and application of novel drug-nanoparticle conjugates, and the efficacy of nanocomposites using animal models. He is looking to identify the mechanisms by which nanocomposites impart protective effects against bacterial and cancer cell growth.

Additionally, Prof. Pal uses bioinformatics tools and computational models to solve molecular structures of nanoparticles and nanocomposite material. Through bioinformatics, he aims to understand the genetic alterations in heavy metal resistant bacteria.

Soil-dwelling actinomycetes are the most relevant class of microorganisms to expand one’s knowledge on antimicrobial substance production. Most clinically important antibiotics originate from them. However, multidrug resistance is threatening the future continual use of antibiotics. Hence there is a need to develop alternative environmentally friendly processes of nanoparticle synthesis which involves utilization of biological systems as nanofactories thereby promising an environmentally clean, nontoxic and economical process. Dr. Calcuttawala’s research interest is directed at sampling the soil actinomycetes of East Kolkata Wetlands (EKWs) and screening them for antimicrobial substances and nanoparticle production against a wide panel of phytopathogens. The EKWs have been designated as "wetland of international importance" under the Ramsar Convention in 2002. Microbial richness of this region is its hidden asset. Soil samples collected from the wetlands are expected to show the presence of various new strains of Actinomycetes which are not only ecologically important but also have commercial value. Furthermore, the nanoparticles synthesized may exhibit a synergistic effect with the antimicrobial substances produced by them and can serve as effective tools in overcoming the roadblock of controlling those phytopathogens which are difficult to eradicate using the conventional agricultural methods.

Dr. Argha Chakraborty is investigating the relationship between surface chemistry and topography of biomaterials mainly to understand the anti-infective response mechanisms of fungal cells. His research helps combat fungal infections from biomedical devices and directed towards presenting long term solutions for preventing fungal outbreaks from healthcare settings in highly populated areas.

Dr. Chakraborty has also been involved in the development of innovative vaccine delivery systems that can reduce the chances of blood-borne infections due to needle-stick injuries in immunisation programs. With an international recognition, Dr. Chakraborty is aiming to tackle the problems of fungal infections with the help of scientifically translatable point of care technologies.

Specifically, Dr. Chakraborty is designing approaches to study the interface between cells (both human and microbial) and materials surfaces with the help of plasma based surface modification technologies like plasma polymerisation and Deep Reactive Ion Etching (DRIE). On surfaces, plasma polymerisation can provide a chemical modification with the presence of (traditionally) hydrocarbon based cross linked polymers containing reactive functional groups such as aldehyde, epoxide, alcohol, carboxide, etc., whereas in case of DRIE, a physical modification of surfaces can be achieved. Thus, with the help of these surface modification tools, Dr. Chakraborty is advancing our understandings of biomaterials design and tissue engineering for the development of anti-fungal devices.

Dr. Jana is involved in research to understand the structure, dynamics, and thermodynamics of complex biomolecular systems at atomistic resolution using theory and computational tools.  One of the major focusses is to understand the self-assembly pathways of the intrinsically disordered proteins, which is linked to a variety of "protein aggregation disorders" such as Alzheimer's, Parkinson's and Huntington's diseases, and the modulation of their aggregation pathways with suitable nanomaterials and ligand binding using computer simulation techniques.

Since last year, Dr. Jana is also investigating SARS-COV-2 induced amyloid formation as a way to explain some of the long-term effects troubling COVID-19 survivors. For instance, symptoms of “Long COVID” and the Multisystem Inflammatory Syndrome in adults (MIS-A) resemble Serum Amyloid A (SAA) amyloidosis, and SAA overproduction is a symptom of COVID-19. Similarly, it has been shown that SARS-COV-2 infection can trigger Parkinson’s disease which is connected with alpha-Synuclein amyloid formation. We suspect similar relationships with amyloid-beta peptide, implicated in Alzheimer’s disease.

Dr. Amit Sarkar’s research programme primarily focuses on molecular genetics of enteric pathogenic bacteria and their interactions with hosts. During doctoral research Dr. Sarkar focused on molecular characterization of Non-Cholera Vibrios to gain better insights towards their genetic differences with their epidemic causing counterparts. His postdoctoral research primarily focused on understanding the host-pathogen interaction and identification of novel virulence genes of Lyme disease causing bacteria Borrelia Burgdorferi. Antimicrobial resistance (AMR) is a growing concern worldwide where rampant use of antibiotic has resulted in the emergence of antibiotic resistant strains. Infections with the enteric pathogen Vibrio cholera remains a concern in some of the South-East Asian countries and has emerged as a notorious drug resistant enteric pathogen over the past few decades. How these bacteria have evolved to acquire this drug resistance property and their survivability within the gut of the host in competition with the normal gut flora is one of the primary questions of Dr. Sarkar’s research. His research also aims at molecular characterization of hospital-acquired Salmonella infection and their antibiotic resistance profile.
