Bacillus sp. mutant for improved biodegradation of Congo red: random mutagenesis approach.

Bioresource technology - 1 Dec 2009

Gopinath Kannappan Panchamoorthy, Murugesan Shreela, Abraham Joanna, Muthukumar Karuppan

Abstract excerpt

This study presents the improved biodegradation of Congo red, a toxic azo dye, using mutant Bacillus sp. obtained by random mutagenesis of wild Bacillus sp. using UV and ethidium bromide. The mutants obtained were screened based on their decolorization performance and best mutants were selected for further studies. Better decolorization was observed in the initial Congo red concentration range 100-1000 mg/l for...
