Spectroscopic characterization and identification of Pseudomonas fluorescens mediated metabolic products of Acid Yellow-9.
Pseudomonas flourescens NCIM 2100 was obtained from NCL, Pune, India, that was adapted to growth on 4 amino 1-1 azo benzene 3,4-Disulfonic acid. This strains was tested by UV, (1)H NMR, and IR spectroscopy for its ability to degrade the dye which resulted in to sulfonated analogs namely p-amino benzene sulfonic acid sodium salt and 2,4 diamino benzene sulfonic acid sodium salt. These compound further changed to either 2,4 dihydroxy benzene sulfonic acid sodium salt or 2 amino 4 hydroxy benzene sulfonic acid sodium salt, or 4 amino 2 hydroxy benzene sulfonic acid sodium salt. These breakdown compounds were non toxic in nature.
