Biodegradation of plasticizers by Rhodotorula rubra - setac
The degradation of D (PG)DB or D (EG)DB led to a significant increase in solution toxicity, which was associated with the production of metabolites resulting from the incomplete breakdown of the plasticizers. The toxic metabolites in the D (PG)DB system were identified as isomers of dipropylene glycol monobenzoate.

The plasticizers included the commonly used bis-2-ethylhexyl adipate (B (EH)A), dioctyl phthalate (DOP), and dioctyl terephthalate (DOTP), and the less commonly used dipropylene glycol dibenzoate (D (PG)DB) and diethylene glycol dibenzoate (D (EG)DB).

Mechanisms of biodegradation of dibenzoate plasticizers
However, earlier studies have shown that the interaction of Rhodotorula rubra with dibenzoate-based plasticizers resulted in incomplete microbial degradation leading to the accumulation of monobenzoates, which had significantly higher toxicity than the original plasticizers (Gartshore et al., 2003).
- Does glucose degradation of plasticizers occur in Rhodotorula rubra j-96-1?
- The degradation of plasticizers by the yeast Rhodotorula rubra J-96-1 (American Type Culture Collection 9449) in the presence of glucose was studied.
- Does Rhodotorula rubra interact with dibenzoate-based plasticizers?
- However, earlier studies have shown that the interaction of Rhodotorula rubra with dibenzoate-based plasticizers resulted in incomplete microbial degradation leading to the accumulation of monobenzoates, which had significantly higher toxicity than the original plasticizers (Gartshore et al., 2003).
- 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).
- Does rhodochrous biodegrade hexanediol dibenzoate?
- The results of biodegradation of 1,6-hexanediol dibenzoate by R. rhodochrous are presented in Fig. 2 a and b with either hexadecane or tetradecane, respectively, as the co-substrate carbon source. In both cases, the dibenzoate was degraded and benzoic acid was produced and then degraded.
- What is the biodegradation of diethylene glycol and dipropylene glycol?
- Subsequent biodegradation of the monobenzoates of diethylene glycol (D (EG)MB) and dipropylene glycol (D (PG)MB) was very slow, leading to significant accumulation of these monoesters.
- Are dibenzoate plasticizers biodegradable?
- Biodegradation mechanisms established for the dibenzoate plasticizers demonstrate that the presence of the ether function leads to significant quantities of toxic metabolites. This, in turn, can be seen to be an important consideration in the design of green plasticizers.
