INTRODUCTION
‘Chilika’ is the largest lagoon in the subcontinent which is
situated along the east coast of India between latitude 19o
28’ and 19o 54’ N, and longitude 85o 05’ and 85o 38’E.
This is a shallow, brackish-water lake formed due to the
silting action of the Mahanadi River, which drains into the
northern end of the lake, and the northerly currents in the
Bay of Bengal, which have formed a sandbar along the
eastern shore (Arya and Lakhotia, 2006). It is the largest
brackish water wetland complex in Asia, declared as a
Ramsar site under the convention on “Wetlands of
International Importance”. This lagoon is presently under
threat from both natural and anthropogenic pressures
(Nayak et al., 2004). The marine realm constitutes the
major habitat of the biosphere covering 73 % of the earth
surface which provides the largest inhabitable space for
living organisms, particularly microbes. Marine microbes
flourish not only in the surface water of the sea, but also in
the lower and abyssal depths from coastal to the offshore
regions and from the general oceanic to the specialized
niches like blue waters of coral reefs to black smokers of
hot thermal vents at the sea floor.
As the water being served as major solvent, it plays an
important role in the pharmaceutical industries.
