Pollution control is one of the prime concerns of society
today. Untreated or partially treated wastewaters and industrial
effluents into natural ecosystems pose a serious problem to the
environment. Among the industrial wastewaters, the removal of
color from dye bearing effluents is one of the major problems
due to the difficulty in treating such wastewaters by conventional
treatment methods. This is because synthetic dyes have
a complex aromatic molecular structure, which makes them
more stable and difficult to biodegrade [1]. Although number
of processes like flocculation, chemical coagulation, precipitation,
ozonation and adsorption has been employed for the
treatment of dye bearingwastewaters, they possess inherent limitations
such as high cost, formation of hazardous by-products
and intensive energy requirements [2]. Biological processes such
as bioaccumulation and biodegradation have been proposed as
having potential application in removal of dyes from dye bearing
wastewater
