  Abstract

The dyeing processes in the textile industry generate substantial wastewater containing various dye compounds, particu larly triphenylmethane dyes, which are environmentally problematic due to their persistence and potential toxicity. This study focuses on optimizing the decolorization of three specifc triphenylmethane dyes (Basic Green 4, Basic Violet 3, and Bromophenol Blue) using bacterial monoculture and consortium isolated from textile wastewater. Initially, bacterial strains (Agrobacterium radiobacter, Bacillus sp., Sphingomonas paucimobilis, and unidentifed flamentous bacteria) were isolated and screened for their decolorization capabilities. The most efective strains were then selected for detailed monoculture and consortium studies. Key parameters such as pH, temperature, stirring, initial dye concentration, glucose, and yeast extract were optimized to enhance decolorization efciency. The results showed that both monocultures and consortium had signifcant decolorization capabilities, with the consortia outperforming the monocultures under optimized conditions. The consortia exhibited enhanced decolorization efciency compared to individual bacterial strains, indicating synergistic interactions among the consortium members.
