Exploiting oilfield
site microbes for
diverse applications:
ANorth East Indian
perspective

This paper reports the
microorganisms isolated
from crude oil contaminating
sites of North East Indian
petroleum fields about our
contribution towards their
laboratory and field scale
applications for biosensing,
bioremediation and enhanced
oil recovery in technological
perspectives. The work was
carried out under a program
supported by Oil and Natural
Gas Commission Ltd (ONGCL)
India. Out of 150 bacterial
strains isolated so far bacterial
strains capable of producing
biosurfactant suitable for
enhanced recovery of crude oil
(EOR) have been developed.
Two promising biosurfactant
producing bacterial strains
identified and screened as
Achromobacter sp. TMB1
[NCBI accession no. KX661383]
Pseudomonas sp. TMB2 [NCBI
accession no KX661384] after
16s rDNA sequencing was
found to have physiochemical
properties useful for operational
and remedial activity in
petroleum production Redox
enzymes such as cytochrome
P450 monooxygenase has
been induced for their use
as recognition element in
biosensor design. Cytochrome
P450 enzyme isolated from
an extremophile Bacillus
Stratosphericus sp. was used
as the recognition element
for an ion-sensitive field
effect transistor (ISFET)-
based biosensor microbial
consortium has been
developed for bioremediation
of crude oil contaminated
site which includes species of
Achromobacter and Bordetella.
The isolation and morphological
characterization of the bacterial
strains includes from crude
oil contaminated soil and
Formation water collected
from the GGSs of Khoraghat
and Merapani ONGCL, India,
indicated the presence of
multiple bacterial species which
can utilize hydrocarbon as a
nutritional source and could be
potential agents for effective
remediation of crude oil
contamination.
Biography
Tapas Medhi is currently
working as Assistant Professor,
Tezpur University. He has
received his Doctoral degree
on 25 August, 2004 from the
Indian Institute of Technology,
Kharagpur, India. He has
completed his Masters of
Science in Agriculture from the
Assam Agricultural University,
India. He then worked at the
Institute of Biochemistry,
Leipzig University, Germany
as Postdoctoral Fellow in
a DFG funded project for
two years and as Assistant
Professor at Tezpur University
in India since 2006. He has
authored several publications
in various journals. His
publications reflect his research
interests in Cytochrome P450
Biochemistry, biopesticides
and bioremediation of crude
oil contaminated soil. He is
currently in charge of two
ongoing scholarly projects on
Phytoremediation and Microbial
enhanced oil recovery.
