Bio-degradation of Azo dye by the Bacteria isolated from Textile Industry Effulent of Solapur district

Abstract

Nowadays, water pollution is one of the major problems which the world is facing. Many factors are responsible for water pollution, among the various reasons, one of the major reason is the dyes released from the textile industry, as they contains numerous numbers of chemicals and heavy metals which affect the water and its habitats which are responsible for health problems in humans like cancer and other diseases in humans. In order to control this, elimination of azo dyes which is being released from the textile industries is necessary. In order to eliminate this, biological approach has been applied. In the present investigation, we isolated around 5 different bacterial strains from the textile effluents collected from industrial area of Solapur, Maharashtra. India in which the strain KL (SN) was found to decolorize the malachite green upto 40mg/1000ml with a 70.39% decolourization at a temperature of 280C and at a pH of 7 at 120 rpm for 4 days which was found to be highest than other strains. Further the strain KL (SN) was found to have 99.9% similarity with Tistrella mobilis.
