Research Thrust

The Division of Microbiology serves as a lead centre for development and commercialization of biofertilizers. Liquid bioinoculants for Azotobacter chroococcumand phosphate solubilizing bacteria with a shelf-life of 30 months have been developed and filed for patents. The novel strategy of biofilmed biofertilizers aims at using fungal (Aspergillus awamori, Trichoderma viride and Priformospora indica) and cyanobacterial (Anabaena torulosa) matrices for plant growth promotion as well as protection. The Division has developed consortia of hyper lignocellulolytic fungi (Aspergillus nidulans, Trichoderma viride, Phanerochaete chrysosporium and Aspergillus awamori) for rapid decomposition of agro-residues. Several biocontrol agents against plant pathogenic fungi and theirmodes of action have been identified. Gene(s) involved in the fungicidal activity wereidentified and strategies have been developed for their utilization. The Division has the germplasm of bacteria and cyanobacteria isolated from extreme environments that can tolerate low and high temperature of 4 and 90oC, 25% NaCl concentration and pH of 3.0. The major research thrust areas of the Division are:

  • Plant –microbe interaction for nutrient acquisition and growth promotion as well as protection
  • Organic matter decomposition for improved soil fertility and health
  • P solubilising and mobilizing microorganisms for enhancing P-use efficiency
  • K-solubilizing microbes for improving K-availability and mechanism of K solubilization
  • Formulation of biofilmed biofertilizers for nutrient management and biocontrol measures
  • Understanding the mechanism and isolation of microorganisms with biocontrol capabilities
  • Diversity analysis of eubacteria and archaebacteria in extreme environments
  • Technology development for production of second generation biofuel
  • Understanding and application of anaerobic microbial processes of agricultural importance
  • Economic utilization of blue green algae and microalgae for value added products
