The kinetics of the biodegradation of two commercial plasticizers, diethylene glycol dibenzoate (D (EG)DB) and dipropylene glycol dibenzoate (D (PG)DB), as well as two alternative...
Biodegradation kinetics of dibenzoate plasticizers and their
A study of the kinetics of the biodegradation of dibenzoate plasticizers demonstrated the importance of ether bonds and alkyl branches on the rate of biodegradation of plasticizers and their metabolites. Removing the ether bond significantly enhanced the biodegradation rate of the monobenzoates.
Mechanisms of biodegradation of dibenzoate plasticizers
The objective of this study was to investigate the effect of the ether function on the biodegradation mechanisms of dibenzoate plasticizers. This was done by comparing the biodegradation mechanisms of the two commercial dibenzoate plasticizers with that of 1,6-hexanediol dibenzoate, a potential green plasticizer. 2. Materials and methods.
Mechanisms of biodegradation of dibenzoate plasticizers
Biodegradation mechanisms were elucidated for three dibenzoate plasticizers: diethylene glycol dibenzoate (D (EG)DB), dipropylene glycol dibenzoate (D (PG)DB), both of which are...
Mechanisms of biodegradation of dibenzoate plasticizers
Biodegradation mechanisms were elucidated for three dibenzoate plasticizers: diethylene glycol dibenzoate (D(EG)DB), dipropylene glycol dibenzoate (D(PG)DB), both of which are commercially available, and 1,6-hexanediol dibenzoate, a potential green plasticizer. Degradation studies were done using Rh
- Does diethylene glycol dibenzoate biodegrade?
- No articles found. The kinetics of the biodegradation of two commercial plasticizers, diethylene glycol dibenzoate (D (EG)DB) and dipropylene glycol dibenzoate (D (PG)DB), as well as two alternative plasticizers, 1,3-propanediol dibenzoate and 2,2-methyl-propyl-1,3-propanediol dibenzoate, were investigated in an aerated bioreactor.
- Are dibenzoate plasticizers biodegradable?
- Kinetic models were developed in order to describe the biodegradation of a selection of dibenzoate plasticizers and to evaluate their relative biodegradability. The system used for this kinetic study consisted of resting cells of R. rhodochrous, previously grown on hexadecane in a bioreactor.
- Does ether function affect the biodegradation mechanisms of dibenzoate plasticizers?
- The two most important commercial dibenzoate plasticizers, diethylene glycol dibenzoate (D (EG)DB) and dipropylene glycol dibenzoate (D (PG)DB), both contain ether functions. The objective of this study was to investigate the effect of the ether function on the biodegradation mechanisms of dibenzoate plasticizers.
- What is the biodegradation of plasticizers D (EG)DB and D (PG)MB?
- The biodegradation of the commercial plasticizers D (EG)DB and D (PG)DB by the yeast, R. rubra, resulted in the formation of substantial amounts of the metabolites, diethylene glycol monobenzoate (D (EG)MB) or dipropylene glycol monobenzoate (D (PG)MB) (Gartshore et al., 2003).
- Why are monobenzoates biodegraded quickly?
- The rapid biodegradation of monobenzoates released from microbial hydrolysis of alternative dibenzoate plasticizers was attributed to the lack of an ether bond in these compounds.
- How is plasticizer biodegradation modeled?
- Biodegradation of plasticizers and their associated metabolites were modeled using a Monod-type kinetic model. Significant differences between the biodegradation of commercial and alternative plasticizers were observed both in the biodegradation pathway and the biodegradation rates of monobenzoate metabolites.
