Abstract
The effluents from textile industries without proper treatment contains a remarkable amount of synthetic dyes which are harmful to the environment and a big challenge globally to degrade it with a eco-friendly way. Conventional methods are extremely energy-consuming, non-effective and generate a toxic sludge impacting the environment. Several microorganisms can be utilized to treat these effluents. The research deals with five bacteria isolated from textile effluent and their consortium for the biodegradation ability of Novacron dyes. The isolates were identified through the Biolog™ identification system and molecular technique. Biodegradation was confirmed by measuring optical density (OD) optimizing conditions (pH 7.0, temperature 37 °C, 10 % inoculums and 100 mg/L dye) under static condition. The isolates started decolourization at 24 h whereas, the consortium started decolourization at 18 h and exhibited a maximum after 72 h. The presence of low molecular weight protein as metabolite supported the biodegradation and non hazardous to environment. This study revealed that these bacteria might have degradation potentials, and research results will help to set up dye removal eco-friendly methods to expose the dye effulents to environment in future.
