Biodegradation of endocrine disruptor dibutyl phthalate (DBP
DBP biodegradation kinetics was explained by the Monod growth inhibition model. Values for maximum specific growth rate ( max) and half-velocity constant ( K s) are 0.07 h 1 and 998.2 mg/l, respectively. Stoichiometry for DBP degradation was calculated for Methylobacillus sp. V29b.

Biodegradation of endocrine disruptor dibutyl phthalate (DBP) by a newly isolated Methylobacillus sp. V29b and the DBP degradation pathway 3 Biotech. 2016 Dec;6 (2):200. doi: 10.1007/s13205-016-0524-5. Epub 2016 Sep 21. Authors Vinay Kumar 1 , S S Maitra 2 Affiliations
Mass balance and kinetics of biodegradation of endocrine
Amir et al. (2005) reported similar observations on the intermediates formed during biodegradation of diethyl hexyl phthalate (DEHP), DMP and dibutyl phthalate (DBP). Many other studies ( Ahmadi et al., 2017 , Navacharoen and Vangnai, 2011 , Singh et al., 2017 ) have also reported that the de-esterification is the main step involved in
Mass balance and kinetics of biodegradation of endocrine
Biodegradation of DMP (dimethyl phthalate) and DEP (diethyl phthalate) is a global environmental concern due to their endocrine disrupting nature. In the present study, biodegradation of DEP as the single substrate and a mixture of DMP and DEP as dual substrates were examined in a two-phase partitioning bioreactor (TPPB) using
Genotoxic activity of endocrine disrupting compounds commonly
In the present study we evaluated cytotoxic and genotoxic activities of endocrine disrupting compounds (EDCs), including dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), benzyl butyl phthalate (BBP), di (2-ethylhexyl) phthalate (DEHP), bisphenol A (BPA), and nonylphenol (NP), which have been previously identified in
- Does ESTG degrade dibutyl phthalate?
- EstG was also engineered to be efficiently secreted by B. subtilis. A recombinant bacterial consortium removes 70% of 1 mM DBP within 5 days. EsteraseG (EstG) from Sphingobium sp. SM42 efficiently degraded the toxic chemical, dibutyl phthalate (DBP).
- Which bacterial consortium is used for biodegradation of dibutyl phthalate (DBP)?
- The bacterial consortium used for the biodegradation of dibutyl phthalate (DBP) consisted of E. coli DE3 harboring the recombinant plasmids, pOprFestG and pDUETestG, expressing surface displayed and intracellular EstG, respectively, and B. subtilis CU1065 carrying pBESestG, which expresses secretory EstG.
- Does bacterial consortium catalyze dibutyl phthalate biodegradation?
- Biodegradation of dibutyl phthalate by a bacterial consortium According to our previous report, esteraseG showed a remarkable ability to catalyze degradation of DBP . After the production and location of OprF-EstG had been confirmed, the dibutyl phthalate biodegradative ability of bacterial consortium was investigated.
- Can aerobic bacteria degrade dibutyl phthalate?
- Epub 2015 Mar 13. 1 State Key Laboratory of Pollution Control and Resource Reuse, and School of the Environment, Nanjing University, Nanjing, 210023, People's Republic of China. An aerobic bacterial strain M11 capable of degrading dibutyl phthalate (DBP) was isolated and identified as Camelimonas sp.
- Can a recombinant bacterial consortium remove dibutyl phthalate (DBP)?
- A recombinant bacterial consortium removes 70% of 1 mM DBP within 5 days. EsteraseG (EstG) from Sphingobium sp. SM42 efficiently degraded the toxic chemical, dibutyl phthalate (DBP). In this study EstG was successfully displayed on the surface of Escherichia coli using the Pseudomonas aeruginosa outer membrane protein, OprF, as a carrier protein.
- Which bacterial strains are involved in biodegradation of DBP?
- Several studies have reported the isolation of bacterial strains that are involved in biodegradation of DBP, for example: Arthrobacter sp. ZH 2 , Gordonia sp. , and Rhodococcus sp. JDC-11 , which use phthalate 3,4-dioxygenase as a major DBP-degrading enzyme.
