Mineralization of high concentrations of the endocrine disruptor dibutyl phthalate by Fusarium culmorum.

ABSTRACT: Dibutyl phthalate (DBP) is a widely used plasticizer, whose presence in the environment as a pollutant raises concern because of its endocrine-disrupting toxicity. Growth kinetics, glucose uptake, biodegradation constant of DBP (k), half-life of DBP biodegradation (t1/2) and percentage of removal efficiency (%E) were evaluated for Fusarium culmorum grown on media containing glucose and different concentrations of DBP (500 and 1000 mg/l). Intermediate compounds of biodegraded DBP were identified by GC-MS and a novel DBP biodegradation pathway was proposed on the basis of the intermolecular flow of electrons of the intermediates identified using quantum chemical modeling. F. culmorum degraded 99% of both 1000 and 500 mg of DBP/l after an incubation period of 168 and 228 h, respectively. %E w
