The Arthrobacter sp. ZH 2 strain was found to efficiently degrade di-n-butyl phthalate, the optimal temperature and pH conversion conditions of which were 30 °C and 9.0, respectively.The degradation of DBP was best fitted by first-order kinetic equation and the half-life was 10.19 h.

Effects of di-n-butyl phthalate and di-2-ethylhexyl

1. Introduction. Phthalic acid esters (PAEs) are a kind of compounds used as additives in plastics to impart flexibility. Di-2-ethylhexyl phthalate (DEHP) and Di-n-butyl phthalate (DBP) are two PAEs, most widely used in the production of industrial plastic products, paints, pesticides, cosmetics, and medical products (Latini et al., 2010; Wang et al., 2013a).
