Abstract

Release of residual dyes into natural water bodies through industrial waste water is considered to be a potential threat to the environment. There are several traditional physio-chemical treatment methods to remove such organic and inorganic dyes, but these are costly and create secondary sludge disposal problems. Bioremediation is offered the best approach to overcome the limitations of traditional methods. Thus, this study was undertaken to isolate bacteria possessing the high potential to degrade the different types of dyes. Total of 12 different dyes decolorizing bacterial isolates were obtained from textile wastewater using enrichment and isolation techniques. Out of these isolates, Citrobacter diverses was found to be the most prominent dyes decolorizing bacteria. It showed 79% to 98% decolorization of MR (Methyl red), MG (Malachite green), CR (Congo red), CV (Crystal violet), CF (Carbol fuchsin) dyes within 72 h. It showed maximum decolorization in presence of optimum growth conditions like 1.5gm/L yeast extract, sucrose, and glucose as a carbon source, peptone, and NH4SO4 as a nitrogen source of medium pH 7.0 at 37°C. This isolate showed the highest decolorization in its free cell form as compared to its immobilized form. According to these results, the obtained strain of Citrobacter diverses confirms its application in bioremediation process of dyes in In-situ.
