Dr Sarma primarily focusses on the following subjects at the postgraduate level

1. Biochemistry

2. Environmental Biotechnology

3. Plant and Animal Biotechnology

4. Biostatistics and Research Methodology

5. Industrial Biotechnology (Open Course)

Thrust areas of Research:

  • Yeast metabolic regulation and quorum sensing
  • Natural product bioprospecting from microorganisms
  • Physiological and immune responses on Antheraea assama
  • Wildlife genetics of Rhinoceros and Pachyderms
Primary focus: Fungal Biology and Environmental Biotechnology
 
For hundreds of years yeasts have been known to produce substances useful to humans through the process of fermentation. Indigenous yeasts inherent in fermented products perpetuated for thousands of years by ethnic tribes and communities of northeast India has not been appreciated fully. We as a team are involved in deciphering the role of quorum sensing molecules from indigenous yeasts that enhances the possibilities of secondary metabolite production. Besides, the expression of cartotenoids and other pigmented products like photoprotective molecules during the later stages of fermentation by yeasts like Wickerhamomyces anomalous, Pichia spp., Rhodotorula taiwanensis etc are being studied. The role of molecular factors affecting signal communication amongst yeasts like Saccharomyces cerevisiae, Saccharomycopsis fibuligera and Candida glabrata in consortia are studied with much attention to delineate the basis of single spp yeast domination in mixed cultures.
 
 

Natural product bioprospecting from microorganisms

We are also involved in identifying microbes from natural sources that can bioremediate crude oil contaminated sites and can assist in nitrogen fixation in soil. A collaborative work with IASST had assisted us to isolate a Pseudomonas bacteria capable of degrading hydrocarbons in oil field formation water. Two of my students has been trying to identify solutions to problems of fungal diseases in host plants of silkworm through the study of plant microbe interactions.
 
Wildlife genetics of Rhinoceros and Pachyderms
 
Presently, other than yeasts, I am also interested in understanding population genetics of rhino and pachyderms through molecular systematics involving microsatellite markers in an effort to facilitate conservationists and wildlife researchers to design suitable strategies for wildlife conservation. I have been keenly associated with ‘Aaranyak’ for more than 15 years, a SIRO recognized Institute of eminence in the field of Wildlife Conservation and is also an external member of the Wildlife Genetics laboratory of Aaranyak headed by Udayan Borthakur and Dr Bibhab Talikdar.
 
Physiological and immune responses on Antheraea assamamensis Helfer
 
We also do have collaborative association with B Borooah college and Dibrugarh University investigating on characterizing factors affecting immune responses in muga silkworm caused by fungal pathogens and microsporidians that disturb the melanization pathway concomitant to prophenoloxidase activation and inhibition.
