Cloned (Comment) Organism
gene azoA, subcloning in Escherichia coli strain DH5alpha, and constitutive recombinant expression in Pseudomonas fluorescens strain PfO-1 using vector pBBRMCS2 leading to 2fold increased azoreductase activity, coexpression of Mycobacterium vaccae strain N10 NAD+-dependent formate dehydrogenase gene. FDH results in a 3.5-4fold increased dye decolorization, thus developing an in vivo NADH regeneration system using formate as an electron donor. Overexpression of both genes azoA and fdh via transcription fusion under plac and/or pT7 promoters in Escherichia coli strain BL21 (DE3) and Pseudomonas fluorescens strain PfO-1 further increases the RV5R decolorization in formate constituted buffered conditions compared to only azoA or fdh overexpression Enterococcus sp.

General Information

General Information Comment Organism
physiological function the rate limiting first step of the biodegradation pathway of recalcitrant azo dyes is their decolorization, which involves the reductive cleavage of the azo bond catalysed by the enzyme azoreductase. The enzyme from strain L2 decolorizes a wide spectrum of azo dyes Enterococcus sp.
