Biodegradation of Textile Waste by Bacterial Strains

Harmful effects of textile industry effluents are a huge problem for now a days. It creats many problems at different level of ecosystem. The textile industry generates a high volume of waste products. Approx. seventy tons of dye is used annually. A big portion of such amount is discharged in a huge amount of water which affects the quality of water. They are cause of high BOD, COD sulphate, low dissolve oxygen and strong colour, which is the most serious problem of today. The treatment and reuse of industrial waste is now an attractive option as because of the sustainable development of environment and also because of the increasing demand for water and decrease in supply. The removal of waste from the textile effluent has been carried out by physical, chemical and biological methods. The physical and chemical techniques are electrochemical destruction , anion exchange resin, , ozonation, floatation, flocculation, electro floatation, reverse osmosis, irradiation, adsorption, coagulation, nano filtration, ultrafiltration and microfiltration fungal discolouration. The ability of microorganisms to degrade and metabolize a wide variety of compounds has been recognized and exploited in various biotreatment processes. This studyhelps in investigating the chemical, physical along with the biological treatment techniques focusing on the potential of bacterial strains for biodegradation of textile industrial waste.
