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 37°C. 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.
