| Abstract: | Background Microbial degradation of azo dyes is commonly initiated by the reduction of the azo bond(s) by a group of NADH or NADPH dependant
azoreductases with many requiring flavin as a cofactor. In this study, we report the identification of a novel flavin-free
NADPH preferred azoreductase encoded by azoB in Pigmentiphaga kullae K24. |
