Tistrella mobilis, a Novel Bacteria Isolated from Bagru Rajasthan Possess the Capability of Azo Dye Degradation

This study presents degradation of an azo dye, Reactive Red 120, by novel bacteria, isolated from Bagru (Rajasthan). The bacterial strain was identified as Tistrella mobilis JCM 21370 on the basis of 16S rDNA sequence. Reactive Red 120 (92.08 %) was degraded in 10 days (optimum conditions include pH 7 and temperature 30C) in liquid cultures under static conditions. Tistrella mobilis is reported to be polyhydroxyalkanoate producing bacterium. The study shows bacteria is gram negative, rod shaped, possess mobility, positive for catalase and oxidase acitivity. HPLC studies shows bacterium is capable of degrading azo dyes.
