Abstract
The textile effluents contain the synthetic dyes, which are mostly discharged into water
resources without prior treatment. These dyes are very harmful for aquatic life and
microorganisms but also for human beings. These harmful effects become further
severe because the metal ions are present along with the dyes. Hence, there is need to
deal these pollutants simultaneously. Therefore, present study was carried out to isolate
and characterize a bacterium, which showed efficient color removal of reactive yellow2 (RY2) in occurrence of zinc (Zn). For this purpose, Zn tolerant bacterial strains were
isolated and examined for efficient color removal of RY2 in occurrence of Zn. Among
the isolated bacterial strains, degrading capabilities of most effective strain,
Pseudomonas sp. strain LT10 were characterized under different conditions. In
existence of Zn, the strain LT10 exhibited significant decolorization of RY2 and other
azo dyes. Moreover, yeast extract as a carbon co-substrate, showed efficient color
removal of RY2 at pH 7.5-8.5 by the strain LT10. Moreover, the strain LT10 also
revealed considerable decolorization of RY2 even at high levels of Zn. On the basis of
results, it can be concluded that Pseudomonas sp. LT10 can be an efficient bioresource
for treating textile wastewaters containing azo dyes and metal ions.
