Complete mineralization of 2,4-dichlorophenoxyacetic acid in a reduction and oxidation Synergistic Platform (ROSP)
2023, Chemical Engineering JournalUnravelling the contribution of nitrifying and methanotrophic bacteria to micropollutant co-metabolism in rapid sand filters
2022, Journal of Hazardous MaterialsCitation Excerpt :Thus, the absence of biodegradation of BAM, chloridazon, mecoprop, ioxitalamic acid and benzotriazole by AMO could be explained by the presence of the aforementioned functional groups in these compounds (Table S1). Although 2,4-D contains impeding functional groups (chloride), the aerobic pathway of 2,4-D biodegradation can start with the hydroxylation of the acetic acid side chain (Sinton et al., 1986). Similarly, caffeine contains both affinitive and impeding functional groups (Table S1), but the three outside alkyl groups are firstly degraded during caffeine biodegradation (Dash and Gummadi, 2006).
Competition within low-density bacterial populations as an unexpected factor regulating carbon decomposition in bulk soil
2022, Soil Biology and BiochemistryCitation Excerpt :This is precisely the case for the 2,4-Dichlorophenoxyacetic acid (2,4-D) used in this study as a generic model compound (Don and Weightman, 1985; Pieper et al., 1988; Boivin et al., 2005). Bacterial degradation of soil carbon has generally been modeled with the Monod equation, where the specific substrate uptake rate is controlled by substrate concentration and bacterial traits such as the maximum specific growth rate, the yield (or carbon use efficiency) and the “maximum specific uptake efficiency” (e.g. Monod, 1949; Sinton et al., 1986; Cheyns et al., 2010). With the Monod equation, at the lowest substrate concentration, the specific uptake rate is linearly proportional to the substrate concentration.
Exposure of Mytilus trossulus to diclofenac and 4′-hydroxydiclofenac: Uptake, bioconcentration and mass balance for the evaluation of their environmental fate
2021, Science of the Total EnvironmentCitation Excerpt :Banerjee et al. (1984) created model showing the correlation between logKOW of the substance and its biodegradation rate. This correlation is based on penetration of xenobiotic substrates into the cells which limits the biodegradation processes (Banerjee et al.1984; Sinton et al., 1986). Thus biodegradation rate of highly hydrophilic compound like 4-OH DIC is expected to be higher than its parent compound, what is also confirmed in our study.
Combined electrochemical processes for the efficient degradation of non-polar organochlorine pesticides
2019, Journal of Environmental ManagementCitation Excerpt :There are many technologies available for the treatment of wastewaters polluted with organochlorine compounds. The bioremediation technique was tested in 2,4-D removal (Sinton et al., 1986) and for several organochlorine compounds (Neilsen, 1996). Recent developments for the removal of 2,4 -D (Carboneras et al., 2017; Chinalia and Killham, 2006; González-Cuna et al., 2016; Sandoval-Carrasco et al., 2013) and for the removal of atrazine by bioremediation-related technologies have been reported in literature (Noor et al., 2014; Wackett et al., 2002).
An evaluation of 2,4-dichlorophenoxyacetic acid in the Amphibian Metamorphosis Assay and the Fish Short-Term Reproduction Assay
2013, Ecotoxicology and Environmental SafetyCitation Excerpt :This phenomenon is likely the result of limited biodegradation which reduced 2,4-D concentrations to the same extent in all the test vessels, but proportionately this had a greater effect at the two lowest nominal concentrations. A large variety of microorganisms are capable of degrading 2,4-D via aerobic oxidation, and this degradation is maximized at temperatures ranging from 21 to 25 °C (USEPA, 2005; Sinton et al., 1986). Biodegradation likely increased following the first week of exposure due to an increased microbial population in the test vessels that were capable of degrading 2,4-D. None of the analyses of the control vessels exhibited an elution peak at the retention time for 2,4-D at a concentration exceeding the lowest level quantified (LLQ), which was equivalent to 0.120 mg ae 2,4-D/L.
