Screening and characterization of soil bacteria for lignin and textile dye effluent bioremediation and optimization using response surface methodology.

ABSTRACT: In this study, 177 bacterial isolates were recovered from 55 agricultural soil samples collected from various locations in Egypt. Following purification, the isolates were evaluated in solid and liquid phase assays for their capacity to decolorize several types of dyes such as Azure B (AB), methylene blue (MB), and Congo red (CR). The 16S rRNA sequence analysis was used to identify isolates with the highest decolorizing capacity. The two bacterial isolates coded 304 and 434 which exhibited potential ligninolytic activity were identified as Streptomyces griseorubens and Streptomyces intermedius, respectively. Streptomyces intermedius test isolate was selected for optimization experiments using the one-factor-at-a-time approach (OFAT) followed by a statistical method of optimization using re
