In contrast, Mohana et al (23) report that using a microbial consortium applied in the treatment of water contaminated with direct black 22 (solophenyl black), obtained as degradation products 1-naphthol and diphenylamine as a product of anaerobic reduction, similar results obtained by Chavez (24), but using microbial consortia isolated from the Alseseca River of the City of Puebla, Mexico, these products are toxic so it would be convenient to use oxidation mechanisms with laccases or peroxidases and not chemical reduction.
