Isolation and Screening of Azo Dyes Tolerant Bacteria in Semi-Scale Industrial Effluents


Dyes are organic compound have colouring properties of the object which used in industrial application. Huge effluent are releasing by industrial processing, where the microorganism may naturally adopted against particular problems. Present work focused over the selection and screening few best native candidates from diverse bacteria from semi-skilled dye industrial effluent. From eleven isolated bacterial colonies only two are found resistant against azo dyes (Methyl orange and Trypan blue). During the screening it observed that isolates of bacteria (VN1 and VN2) were tolerates and decolorize azo dye up to 500 ppm. These bacterial strain can be used efficientlyremoval of dyes contamina-tion from ex-situ and in-situ.
