Properties of NAD (P) H azoreductase from alkaliphilic red bacteria Aquiflexum sp. DL6.

Azoreductase plays a key role in bioremediation and biotransformation of azo dyes. It initializes the reduction of azo bond in azo dye metabolism under aerobic or anaerobic conditions. In the present study, we isolated an alkaliphilic red-colored Aquiflexum sp.

Enzymatic transformation of nitro-aromatic compounds by a flavin-free NADH azoreductase from Lysinibacillus sphaericus.

Azo dyes and nitro-aromatic compounds are the largest group of pollutants released in the environment as industrial wastes. They create serious health and environmental problems. Azoreductases catalyze the reduction of azo dyes and nitro compounds to their respective amines.
