Screening of environmental bacteria for multiple dye decolorization capabilities in textile wastewater

Textile industry effluents are rich in microorganisms capable of dye decolorization, including bacteria, actinomycetes, and yeast. Conventional microbiological techniques were used to isolate these bacteria, with 10 strains selected for screening. These cultures belonged to Enterococcus, Bacillus, Pseudomonas, Xanthomonas, Sporolactobacillus, and Enterobacter genera. The decolorization of these dyes was examined using UV-visible spectrophotometers, revealing varying resistance and sensitivity to antibiotics.
