BIODECOLORIZATION OF REACTIVE RED HE7B AND REACTIVE ORANGE 3R THROUGH INDIGENOUS BACTERIAL ISOLATE MICROBACTERIUM ORYZAE STRAIN JC8 ISOLATED FROM TEXTILE EFFLUENT

Ravi Kant Rahi and Varsha Gupta

Abstract

Residues of azo dyes are the main pollutants released from textile industries which increases the toxicity level of local water bodies. This study is focused to find out the indigenous bacterial isolates which have the potential to degrade reactive azo dyes. Total 21 bacterial isolates were isolated from textile effluent among them JC8 isolate showed the dye degrading potential which is identified as Mycobacterium oryzae JC8 Strain through 16S rRNA technique. GenBank accession no. MN462556 is assigned by NCBI for particular strain after submitting the data into GenBank database. 89.2% of reactive orange 3R and 84.6% of reactive red HE7B has been successfully decolorized by Mycobacterium oryzae JC8 Strain. Bio decolorization of these dyes were determined through UV-Vis spectrum analysis. High biodegradation rate of these isolates in natural conditions indicates the potential in treatment of azo dyes in a vast level.
