Bacterial taxonomy & Systematics with special emphasis on Phototrophic purple Bacteria, Molecular Phylogeny, Prokaryotic diversity of extremophiles and their bioprospecting.


The microbial world is the largest reservoir of biodiversity, which can be continuously explored and exploited for novel bioactive molecules used in therapeutic and Industrial applications. Our research team is currently working on several aspects of exploration and bioprospecting of microbial resources for antimicrobials for therapeutic applications, and industrially important enzymes for bioremediation of PET polymers and Lignocellulosic Biomass. We mainly focussed on the discovery and development of novel antimicrobial photosensitizes from photo-responsive microbial pigments such as bacteriochlorophylls, carotenoids, chlorins, indole/pyrrole derivatives and etc., which can be used in the non-invasive treatment of microbial infections (especially tropical applications like, wound, scalp, skin and etc.) through photodynamic therapy (PDT). Parallelly, we are also exploring and describing potential novel microbial taxa and studying the culturable microbial diversity of various ecological niches through a polyphasic taxonomic approach.
