icrobial enhanced oil recovery (MEOR) is an alternative
to EOR methods having advantages like low toxicity,
bioequivalence, biodegradability, and economic feasibility
for field implementation. The in-situ and ex-situ production
of microbial metabolites and their application in laboratory
scale study as well as in actual oil field condition, have their
own merits and demerits, which require a multidisciplinary
effort comprising of tools from Geophysics, Microbiology,
Biochemistry, Soil Science, Chemical Engineering and
Mechanical Engineering. Biosurfactants are amphipathic
substances produced by a group of microbes like
Bacillus
sp., Pseudomonas sp., Alcaligenes sp., Achromobacrers sp.,
Burkholderia sp., Clostridium sp., Rhodococcus sp
., etc.,
which play an imperative role in effecting efficient enhanced
oil recovery through surface and interfacial tension (IFT)
mitigation, wettability alteration, and viscosity reduction to
increase permeability, etc. But, the main drawbacks to using
biosurfactants of microbial origin in MEOR are their higher
production cost and low production rates. Therefore, in this
article, we primarily focused on different biotechnological
approaches for incrementing biosurfactant production. Also,
we have summarized the success story of biosurfactant based
MEOR technology in laboratory scale as well as in the field scale
highlighting the economics crude oil recovery.
Speaker Biography
Tapas Medhi is currently working as Assistant Professor of Biochemistry
and Bioprocess Engineering in the Department of Molecular Biology
and Biotechnology, Tezpur University, Assam, India. He received his
PhD from the Indian Institute of Technology (IIT), Kharagpur, India.
He completed his Master of Science in Agriculture from the College of
Agriculture, Assam Agricultural University, India. He then worked at the
Institute of Biochemistry, Leipzig University, Germany as Postdoctoral
