Isolation and molecular characterization of azo-dye degrading bacteria from soil

Abstract

Synthetic dyes from textile industries are common contaminants of water and possess serious environmental health hazards. The aim of the present study was to isolate and identify soil bacteria capable of degrading azo dyes. In the study, bacterial isolates capable of degrading azodye such as methyl red, were isolated from dye contaminated soil. Molecular characterization by 16S rRNA was done for the selected bacterial isolates. Isolated species was identified as Bacillus aryabhattai B8W22., which showed maximum degradation (89.29%) of methyl med dye under standard conditions.
