Abstract

Textile dyes with different chemical structures are consistently used in textile industries and they are being recalcitrant xenobiotic in nature. The aim of present research is directed to finding the preference of striking carbon and nitrogen sources on remazol golden yellow decolorization. Bacterial strains were isolated, screened and tested for dye degradation of remazol golden yellow in basal medium amended with different carbon and nitrogen sources. This study was carried out for the period of 12 d at 37C. Among various carbon and nitrogen sources, starch and yeast extracts promote maximum decolorization in the medium inoculated with Bacillus. sp. (ESL-52). Nevertheless, the rate of decolorization was less in the medium amended with various carbon and nitrogen sources in the presence of Bacillus sp. (TSL-9), Micrococcus sp. (TSL-7), Pseudomonas sp. (M-1) and Staphylococcus sp. (ES-37) respectively. The results clearly showed that addition of significant organic carbon and nitrogen sources are only desirable co-substrates for bacterial dye decolorization process.
