1 Introduction
The release of colored wastewater from textile industries in the ecosystem has been
a great environmental as well as public health concern over the decades. Textile
industry is a promising market due to the customer
'
s increasing demand for new
products. To ful
ll these demands, textile industries are using selective dyestuffs
among 100,000 different commercially available dyes (Husain
2006
). Over
20
40 % of the dyes used in textile industries released to the environment via
-
ef
uent discharge (Song et al.
2008
) which causes serious environmental problems.
However, growing importance of green practices encourages the adaption of
microbe-based wastewater treatment
uents (Christie
2007
). Several physical, chemical and physicochemical methods have been used for
textile wastewater treatment, but each of them has their own advantages and dis-
advantages. Physico-chemical methods of wastewater treatment are not only costly
methods, but also, some cases, very dif
technologies for textile ef
cult to apply. Biological degradation and
decolorization using microorganisms, on the contrary, provides inexpensive,
effective, and speci
c, less energy intensive and eco-friendly methods for textile
wastewater treatment (Robinson et al.
2001
).
