“…These compounds easily leach out, and they have been found to be ubiquitously distributed in the environment, including marine ecosystems (Andrady 2011;Giam et al 1978; Thompson et al 2009). Furthermore, environmental pollutants in terrestrial environments flow into the sea, the final destination.…”

Eleven phthalate-degrading bacterial strains were isolated from seawater collected off the coast of Japan. The isolates were found to be most closely related to the marine bacterial genera Alteromonas, Citreicella, Marinomonas, Marinovum, Pelagibaca, Rhodovulum, Sulfitobacter, Thalassobius, Thalassococcus, Thalassospira, and Tropicibacter. For the first time, members of these genera were shown to be capable of growth on phthalate. The plate assay for visual detection of phthalate dioxygenase activity and PCR detection of a possible gene encoding 4,5-dihydroxyphthalate decarboxylase indicated that phthalate is degraded via 4,5-dihydroxyphthalate to protocatechuate in all the isolates.

“…Dimethyl phthalate (DMP) is an important synthetic organic compound widely used as plasticizers and additives in plastics manufacturing and moulding to improve mechanical properties of the plastic resin, particularly flexibility, and softness (Giam et al 1978). It is typically used in cellulose-ester based plastics, such as cellulose acetate and butyrate.…”

Degradation of dimethyl carboxylic phthalate ester by Burkholderia cepacia DA2 isolated from marine sediment of South China Sea

et al. 2008

Burkholderia cepacia DA2, isolated from marine sediment of the South China Sea, is capable of utilizing dimethyl phthalate (DMP) as the sole source of carbon and energy. During the transformation of DMP in batch culture, its corresponding degradation intermediates were identified as monomethyl phthalate (MMP) and phthalate acid (PA) sequentially over the time of incubation. The biodegradation biochemical pathway of DMP was DMP to MMP and then to PA before mineralization. Degradation of DMP by B. cepacia DA2 was also dependent upon DMP-induction, and the initial concentrations of DMP affected the degradation rate. Degradation kinetics fit well with the modified Gompertz model. The optimum pH and salinity was 6.0 and < 5 per thousand, respectively, for DMP degradation by B. cepacia DA2. This study showed that the indigenous microorganisms of the deep-ocean sediments are capable of DMP degradation completely.

“…It has been detected in both freshwater fish (Mayer et al, 1972) and in the marine environment (Giam et al 1978). Koenig et al (1982) exposed reproductive R. marmoratus and cultured developing embryos in both DBP exposed and non-exposed conditions.…”

SynopsisSpecialized life-history attributes of the cyprinodontiform fish, Rivulus marmoratus, allow continuous life cycle testing to reveal effects of chemicals or environmental stresses upon fertilization, fecundity, egg viability, embryonic development, sex ratios, frequency of growth or skeletal anomalies, as well as other biological markers. This study reports responses in fecundity, viability of embryos, and skeletal anomalies during and after exposure of parental fish to the plasticizer, di-n-butylphthalate (DBP). Skeletal anomalies among offspring were classified as mild, moderate, orsevere compared with non-deformed normal offspring. The frequency of skeletal anomalies increased from 4% (all categories combined) in controls, to 10% and 19% of the offspring from adults exposed to 1 and 2 mg 1-l DBP, respectively. DBP treatment was conducted over a 21 week interval, followed by a 9 week post-treatment observation interval. During post-treatment, frequency of skeletal anomalies decreased to less than 5% in all groups.
