Biodegradation of Remazol Brilliant Blue R using isolated bacterial culture (Staphylococcus sp. K2204).

Staphylococcus sp. K2204, a bacterial isolate, was employed in this work to decolorize Remazol Brilliant Blue R (RBBR), which belongs to the anthraquinone class of textile dye. Staphylococcus sp. K2204 biodegraded 100 mg/L RBBR at 37°C under static condition with the help of extracellular laccase and peroxidases. The products of RBBR degradation were characterized using analytical tools including mass spectral technique. The phytotoxicity tests evaluated the toxicity of RBBR and the products of biodegradation. The research outlined here is the first attempt to utilize Staphylococcus sp. K2204 for remediating the wastewater containing anthraquinone textile dye.
