Aerobic biodegradation of di-n-butyl phthalate by

Oct 21, 2014· Di-n-butyl phthalate is widely used as plasticizer, which has been listed as priority pollutant due to its toxic and ubiquitous characteristics. It is diff In this paper, the feasibility of using Micrococcus sp. to bioaugment a sequencing batch reactor for degrading di-n-butyl phthalate (DBP) was investigated.

Biodegradation of di-n-butyl phthalate and expression of

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. ZH 2 preferentially utilized DBP rather than dimethyl phthalate (DMP) when a minimal salt medium was

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).

major routes for environmental degradation of this wide-spread pollutant due to its low rate of the hydrolysis and the photolysis. Xu et al. (2005) studied the biodegradation of an endocrine-disrupting chemical di-n-butyl phthalate ester by Pseudomonas uorescens B-1. Patil et al. (2006) inves-tigated the degradation of DBP by Delftia sp.
