Residual dyes, auxiliaries and chemicals are often left in the process
water and discharged with the wastewater. Therefore the wash off from
the dye house invariably contains large amount of residual dye. The three
major chromophores of various commercial dyes are Azo, Antraquinone and
Indigo. These effluents are discharged to sewers from where they enter into
the Municipal wastewater treatment plants. In the dye-manufacturing units,
there is considerable debate on the level of environmental hazard produced
by coloured effluents. Nonetheless, although the problem of colour could be
argued as only aesthetic, it is accepted that the problemhas to be rectified. Thus,
the mounting pressure on the industry to treat the dye house effluents have
led to a host of new and old technologies competing to provide cost effective
solution to the problem of residual colour imparted by dyes. For the present
work, textile effluent and sludge was used for isolation of dye decolorizes.
Total 21 isolates were selected on the basis of their Gram reaction and colony
characteristics. Both types of organisms, Gram positive and Gram negative
were found present with dominant being the Gram negative species. Then five
potential bacterial and four fungal isolates was selected on the basis of their
dye decolorizing ability of four dyes, basic fuchsin, blue, yellow, and orange. The
complexity of the dye led to variable percentage of decolorization of different
dyes by the same organism. Bioremediation of environmental pollutants
relies on the pollutant degrading capabilities of naturally occurring microbes.
Employing static treatment was successful in not only decolorization of dyes
but extensive degradation of the dyes was achieved. This result was supported
by sharp reduction in toxicity of degradation metabolites on the germination
and early seedling growth in wheat and green gram and the bacterial toxicity,
when compared with original dye compound.
