Our main focus is on exploration and exploitation of India`s rich microbial diversity (both cultivable and uncultivable) for novel bioactive molecules and biocatalysts with application in health, agriculture and industry, and their overproduction using conventional and molecular biology tools. The group is also working on the expression of cryptic biosynthetic pathways of microorganisms.

Mission and goals

  • Development of microbial repository from extreme environments and endophytes of endemic plants

  • To study the plant- microbe interactions for disease management, adaption and optimum production of key metabolites in selected medicinal plants

  • Bioprospecting and characterization of novel endophytes and extremophiles for bioactives and biocatalysts

  • Development of metagenomic libraries from unexplored ecosystems for new/novel bioactives/biocatalysts

  • Production of microbial enzyme and high value microbial products from wild type and  genetically modified strains

  • Metabolic pathway engineering for production of novel/ desired metabolites

  • Hyperexpression and protein engineering of biocatalysts for their application in biotransformation of important drug auxillaries/intermediates.


  • Repository of psychrotrophic, mesophilic and thermo-tolerant microorganism including bacteria, actinomycetes, fungi and endophytes.

  • Metagenomic libraries of environmental samples from unique niches.

  • High altitude medicinal plant gene bank .
