Di-Me phthalate esters (DMPEs), which belong to phthalate esters (PAEs), are widely distributed environmental pollutants with endocrine-disrupting toxicity. The present study focused on a filamentous fungus capable of degrading DMPEs isolated from deep-sea sediments of the Indian Ocean at a water depth of 3300 m using an enrichment culture technique. The filamentous fungus was identified as Aspergillus versicolor IR-M4 based on internal transcribed spacer gene sequence anal. The degradation pathways of three isomers of DMPEs [dimethyl phthalate (DMP), di-Me isophthalate (DMI) and di-Me terephthalate (DMT)] were investigated with this marine fungus. The results showed that A. versicolor IR-M4 was able to degrade DMI to monomethyl isophthalate (MMI) from an initial concentration of 21.52 mg l-1 to undetectable in 2 days of incubation, but without the ability for further degradation of MMI. The marine fungus also conducted sequential cleavage of the ester bonds of DMT to terephthalic acid (TA) via monomethyl terephthalate, and TA was the final end product and was resistant to further metabolism However, this marine fungus was not able to degrade DMP. The different metabolic pathways of the three DMPE isomers by the fungus suggest that the phthalate esterases produced by A. versicolor IR-M4 have a very high substrate specificity for DMPEs and monomethyl phthalate esters (MMPEs).
