Degradation of Di-n-butyl Phthalate by Newly Isolated
Over 87% of supplied di- n -butyl phthalate (DBP) was degraded by JDC-41 in a pH neutral mineral salts medium at 30°C within 48 h. Increased DBP (50–500 mg/L) in the culture correspondingly increased degradation half-life from 3.83 to 18.12 h. DBP induced cells more rapidly degraded DBP.

Variation in metabolism and degradation of di-n-butyl phthalate (DBP) by high- and low-DBP accumulating cultivars of rice (Oryza sativa L.) and crude enzyme extracts Variation in metabolism and degradation of di-n-butyl phthalate (DBP) by high- and low-DBP accumulating cultivars of rice (Oryza sativa L.) and crude enzyme extracts
Degradation of a Plasticizer, di-n-Butylphthalate
A bacterial strain Delftia sp. TBKNP-05 isolated by para-hydroxybenzoate enrichment technique is capable of degrading di-n-butylphthalate (DBP) as a sole source of carbon and energy. Analysis of intermediates by thin layer chromatography and high performance liquid chromatography indicated the presence of monobutylphthalate (MBP), phthalate (PA), and protocatechuate (PCA). The washed cells
Degradation of a Plasticizer, di-n-Butylphthalate by Delftia
The results of the metabolites characterization, oxygen uptake studies, and enzymatic studies suggest that the bacterium degraded DBP by di-esterase to form monobutylphthalate, which is de-esterified by an esterase to form phthalate.
- Does radiation degradation of di-butyl phthalate reduce toxicity?
- Radiation degradation of DBP was effective in decreasing its toxicity. Di-butyl phthalate (DBP), a widely used plasticizer, is ubiquitous in aquatic environments due to the widespread application of plastics. Moreover, DBP is refractory and difficult to remove in biological wastewater treatment process.
- Is di-butyl phthalate refractory?
- Di-butyl phthalate (DBP), a widely used plasticizer, is ubiquitous in aquatic environments due to the widespread application of plastics. Moreover, DBP is refractory and difficult to remove in biological wastewater treatment process. In this study, radiation-induced degradation of DBP was investigated.
- Does sunlight irradiation accelerate photo-degradation of di-butyl phthalate?
- Lin et al. (2023) investigated the performance and mechanisms of the direct photo-degradation of di-butyl phthalate (DBP) in atomized water and the indirect photo-degradation of DBP in the presence of ferric ions and nitrate. They found that the photo-degradation rate of DBP could be accelerated under atomization conditions by sunlight irradiation.
- What is di n -butyl phthalate (DBP)?
- Among various PAEs, di- n -butyl phthalate (DBP) is one of the most frequently identified PAEs in diverse environmental samples and is one of the most widely used plasticizer in China, which has been extensively applied in the processing of polyvinyl chloride as a plasticizer, which can provide good flexibility to products.
- What is the kinetics of DBP biodegradation?
- The kinetics of DBP biodegradation (first-order rate constant and half-life) was determined from the linear regression of the slope on a plot of the logarithm of the DBP concentration in subsamples of the treatment versus time. The DBP degradation data collected in this study can be described by first-order kinetics model as the Eq.
- What are the optimal conditions for DBP biodegradation?
- The optimal conditions for DBP biodegradation were pH 6.9 and 31.7 °C based on the results of RSM. DBP degradation by strain 0426 followed an exponential model and the first-order degradation half-life ranged from 2.95 to 12.56 h for 300–1000 mg/L DBP.
