Extremophiles and extremozymes.
Extremophiles are micro-organisms that inhabit some of earth's most hostile environments and are functional in conditions that were once thought incompatible with life. Our research aims to understand the structural basis of extremophile enzyme stability and catalytic properties. The experimental approaches include microbial screening and isolation, enzymology, molecular biology, proteomics and structure-function studies. The group is also involved in the wide research arena of nanotechnology by working on nanobiocatalysis as well as nanotoxicity. The biomass utilization for production of platform chemicals and enzymes is another engaging aspect where we are actively involved for contributing to circular bio-economy. The expertise of extremophiles, and extremozymes has been optimally manifested for heavy metal and organochlorine bioremediation, thus making a niche in environmental biotechnology/bioremediation.
