Biodegradation of sulfonated aromatic amine by Pseudomonas desmolyticum NCIM 2112
ABSTRACT:
Environmental pollutions caused by the release of wide range
of compounds from various industries such as paper pulp and textiles have a
serious effect on ecosystem and human health. Sulphonated azo dyes represent a
large class of dyes used in textile industries. The precursors of these dyes
are sulphonated aromatic amines. Release of such toxic compounds in the
environment cause toxic effects on soil fertility and aquatic ecosystem.
Limited attention has been paid towards the fate of sulphonated aromatic amines
and substituted sulphonated aromatic amines in the environment previously. The
present research work describes biodegradation of azo dye precursor 1- amino 2-
napthol 4 - sulphonic acid by Pseudomonas desmolyticum NCIM 2112 which was
studied by FTIR and GCMS analysis. The resulting metabolites of biodegradation
include propylmethane thiosulfonate and aminobenzene and they were found to be
nontoxic in the environment.
