My research focuses on understanding the complexity of soil bacterial communities through molecular and biochemical approaches, with the goal of supporting the development of sustainable, eco-friendly biofertilizers.
I have hands-on experience with a broad range of microbiological and molecular techniques, including 16S rRNA gene amplicon sequencing using the Illumina iSeq platform, whole genome sequencing using Oxford Nanopore’s MinION, and Community-Level Physiological Profiling (CLPP) to assess microbial functional diversity.
My work also involves microbial biomass carbon estimation via the chloroform fumigation-extraction method, classical bacterial isolation and phenotypic characterization, plant growth promotion assays, and comprehensive analysis of soil nutrient profiles. These skills collectively support my goal of identifying beneficial microbial taxa for sustainable agricultural practices.
Main Focus
Understanding soil bacterial communities under different cropping systems
Exploring nodulation efficiency of coir dust-based Rhizobium formulations on soybean and black gram
Isolation and characterization of beneficial rhizospheric bacteria
Characterization of composting bacteria
