Complete biodegradation of di-n-butyl phthalate (DBP) by a novel
Di-n-butyl phthalate (DBP) is one of the most frequently observed PAEs in the environment. In this study, a novel bacterium identified as Pseudomonas sp. YJB6 that isolated from PAEs-contaminated soil was determined to have strong DBP-degrading activity.
Biodegradation of di-n-butyl phthalate (DBP) by a novel
DBP is one of important phthalate acid esters (PAEs) that are primarily used to improve the flexibility and workability of the products, such as polyvinyl chloride resins, lubricants, plastic packing films, adhesives, cosmetics, cellulose materials, and insecticides ( Gao and Wen, 2016 ).

Biodegradation of di-n-butyl phthalate (DBP) by a novel
The degradation capability of the strain YJB3 was investigated by incubation in mineral salt medium containing di-n-butyl-phthalate (DBP), one of important PAEs under different environmental conditions, showing 82.5% of the DBP removal in 5days of incubation under the optimum conditions (acetate 1.2g·L -1, inocula 1.8%, and temperature 34.2°C)
Biodegradation of Di-n-Butyl Phthalate by a Newly Isolated
A Gram-negative strain (TJ) capable of growing aerobically on mixed phthalate esters (PAEs) as the sole carbon and energy source was isolated from the Haihe estuary, Tianjin, China. It was identified as belonging to the Sphingobium genus on the basis of morphological and physiological characteristics and 16S rRNA and gyrb gene sequencing. The batch tests for biodegradation of di-n-butyl
- Is di-n-butyl phthalate a PAE?
- Di-n-butyl phthalate (DBP) is one of the most frequently observed PAEs in the environment. In this study, a novel bacterium identified as Pseudomonas sp. YJB6 that isolated from PAEs-contaminated soil was determined to have strong DBP-degrading activity.
- How is DBP biodegraded?
- These results demonstrate that biodegradation of DBP by strain N-1 was firstly hydrolyzed to form MBP, and then further hydrolyzed to produce PA through de-esterification pathway, being similar to DBP degradation pathway by Providencia sp. 2D ( Zhao et al., 2016b) and Gordonia sp. strain QH-11 ( Jin et al., 2012 ).

- What is the primary biodegradation of Paes?
- Typically, the primary biodegradation of PAEs involves the continuous hydrolysis of the ester side-chain, resulting in the formation of a monoester followed by PA (Staples et al., 1997). During the degradation of DBP by strain YJB6, four major metabolites BEP, MBP, PA, BA were identified via GC/MS (Fig. 5; Table S5).
- What is di-n-butyl phthalate (DBP)?
- Di-n-butyl phthalate (DBP) is one of the most abundant PAEs present in the environment (Niu et al., 2014), which has received increasing environmental concerns due to its disruption mutagenic, carcinogenic, and endocrinological effects even at very low concentrations (Heudorf et al., 2007; Mariana et al., 2016).
- Why is photodegradation of DBP inefficient?
- In natural environments, the hydrolysis and photodegradation of DBP are inefficient due to its chemical structure (Net et al., 2015). Microbial degradation is known to be the most effective approach for the thorough removal of DBP from environment (Benjamin et al., 2015; Liang et al., 2008).
