Biodegradation of diisononyl phthalate by a consortium of saline soil bacteria: optimisation and kinetic characterisation

"Diisononyl phthalate (DINP) is one of plasticisers most employed in the production of plastic materials and belongs to the most important environmental contaminants. In this work, a consortium of saline soil bacterial (SSB) capable of degrading DINP is presented. The genera of SSB-consortium w...
