Eco-friendly Degradation of Reactive Red 195, Reactive Blue 214, and Reactive Yellow 145 by Klebsiella Pneumoniae MW815592 Isolated from Textile Waste

The water is used in many textile manufacturing steps beyond cleaning. The quantity and the significant chemical load of the effluents generated constitute the primary challenge of the textile industry. In order to discover new sustainable methods to overcome this problem, the aim of this research was to study the potential for degradation of Reactive Blue 214, Reactive Red 195, and Reactive Yellow 145 using a dye degrading bacterium. Sequencing analysis reveals it to be Klebsiella pneumoniae MW815592. This strain completely decolorized artificial effluent (200 mg/L) after 42 h at pH 9 and 46 °C. The decolorization rate increased in the presence of glucose and yeast extract (2 g). In addition, our finding revealed that the decolorization is due to biodegradation rather than adsorption on the bacterial surface.
