Isolation and Characterization of Dye Degrading Micro-Organisms from Textile Waste Water

Bachelor Thesis from the year 2018 in the subject Environmental Sciences, grade: A, , course: B. Sc Biotech, language: English, abstract: The experiment was carried out to degrade the dyes by using bacterial isolates extracted from textile dye effluents. Five different bacterial isolates were screened and they have capability to degrade and decolorize the textile dye effluents. In the present study, an attempt was made to examine the potential of isolated bacterium for decolorization of lacto phenol cotton blue, Acetocarmine red & Eriochrome black T in batch reactors. Bacteria from textile waste water were subjected to acclimatization with dyes, in the basal nutrient media.

The most promising bacterial isolate was used for further dye degradation studies. Biochemical characteristics

revealed the isolated organism as Pseudomonas spp. The optimum pH and temperature for the decolorization was 6.0 and 37°C, respectively. This decolorization potential increased the applicability of this microorganism for the dye removal.
