Reductive metabolism of aminoazobenzenes by Pseudomonas cepacia

The authors earlier isolated a few strains of microbes in sludge from the sewage of an azo dye factory which had assimilability to azo dye. Among them, strain 13NA was identified as Pseudomonas cepacia based on Bergey's Manual and was named Pseudomonas cepacia 13NA. A model experiment for continuous treatment of dye waste was also reported. Some strain 13NA specificities for aminoazobenzenes and reductive and acetylating pathways are described in the present study.
