Microbial diversity studies of various aerobic and anaerobic ecosystems and their biotechnological applications

Prokaryotes are the dominant form of life on earth and they found to survive under any conditions of the biosphere. We are using an integrated approach to understand the nature of free-living prokaryotes by studying microbial diversity and their ecology. This information provides an insight into the systematics of these prokaryotes and their biotechnological applications. Microorganisms existing in complex environments often require capability to produce antimicrobial compounds as a competitive advantage to producing strains for their establishment in these ecosystems. Although many bacterial strains produce antimicrobial peptides as defensins, only few of them have been characterized in detail. Therefore, our laboratory mainly focused on isolation and characterization of novel antimicrobial peptides including different types of bacteriocins from microbial diversity of aerobic and anaerobic ecosystems. To this effect, we have characterized few antimicrobial peptides produced by strains of Brevibacillus laterosporus. Further antimicrobial peptides produced by other bacterial strains including Bacillus, Paenibacillus, Lactobacillus and Clostridium species are being investigated. The AMPs were purified by HPLC and characterized by MALDI MS/MS analysis. The analyses of the antimicrobial peptides suggested that these strains also produce antimicrobial lipopeptides. My lab is also actively involved in determination of total microbial diversity using both culturable and culture independent approaches. As a part of culturable diversity characterization, we have determined the taxonomic status of few novel prokaryotic strains as novel genera and species.

Write-up of research and development interests/focus, past and present goals:

The lab is engaged in research work related to understanding structure of microbial communities in different marine habitats of the country as systematic sampling of these sites is lacking and diversity data pertaining to these ecosystems are scanty. One of the aims is to understand bacterial diversity from Western Ghats that are one of the major biodiversity hot spots of the world. We aim to focus on sampling selected niches from coastal part of the state Goa and attempt to cultivate hitherto “uncultivated and/or difficult to culture” bacteria. One of our targets is to utilize this overwhelmingly complex bacterial diversity for discovering novel biomolecules with applications in clinical and/or pharmaceutical industry with the premise that “marine habitats offer an increased opportunity for discovering novel biomolecules in lieu of the unique selective pressures of the marine ecosystem where chemical and physical conditions differ significantly from the terrestrial environment that have resulted in production of novel compounds to aid in their survival”. 


 The emphasis of the research group is also concentrated on detailing the abundant bacterial fraction from various environmental habitats using molecular tools such as FISH and CARD-FISH in collaboration Max Planck Institute of Marine Microbiology, Bremen. These techniques are free from biases of PCR based methodologies and can help detect the uncultivable and/or viable but not culturable bacterial cells from phylum to genus level depending on the specificity of the probes.
