Biodegradation kinetics of selected brominated flame retardants in aerobic and anaerobic soil

One-step process for debromination and aerobic mineralization of tetrabromobisphenol-A by a novel Ochrobactrum sp. T isolated from an e-waste recycling site

“…Our results concur with the report that low TBBPA concentration can be easily debrominated with a half-life of 0.59 d (14.2 h) (Gerecke et al, 2006). However, TBBPA biodegradation took more than 100 days (Voordeckers et al, 2002) and up to 430 days (Nyholm et al, 2010) in previous studies. This is because high biodegradation could be achieved at a low substrate concentration (3 mg L À1 ) with relatively high solubility at optimal condition of a high inoculum volume of 25 mL, a pH of 7.0, and a temperature of 35°C in the present study.…”

“…However, most studies investigated whether TBBPA can be debrominated under anaerobic conditions (Arbeli et al, 2006;Iasur-Kruh et al, 2010) or without further degradation in either under anaerobic or aerobic condition (Brenner et al, 2006). Some studies compared the anaerobic debromination of TBBPA with six other BRFs and found that TBBPA was the most difficult to be degraded (Nyholm et al, 2010). To the best of our knowledge, all previous studies focused on the feasibility of TBBPA debromination under anaerobic conditions rather than mineralization in an aerobic system.…”

“…To the best of our knowledge, all previous studies focused on the feasibility of TBBPA debromination under anaerobic conditions rather than mineralization in an aerobic system. A bacterial strain that can directly decontaminate TBBPA has not been isolated up to now, although the anaerobic debromination of TBBPA has been reported previously (Arbeli et al, 2006;Nyholm et al, 2010).…”

Biodegradation kinetics and mechanism of 2,4,6-tribromophenol by Bacillus sp. GZT: A phenomenon of xenobiotic methylation during debromination

“…For instance, some microorganisms in sediment (Arbeli et al, 2006) and anaerobic soil (Nyholm et al, 2010), could debrominate tetrabromobisphenol-A into bisphenol-A. A few strains were also isolated to reductively debrominate mono-, di-, and tribromophenols, and showed the effect of position-selective on the debromination.…”

Vibrational, NMR spectrum and orbital analysis of 3,3′,5,5′-tetrabromobisphenol A: A combined experimental and computational study

“…In November 2010, TBBPA has been restricted and banned on the use of in plastic infant feeding bottle by European Commission (EC) due to the potential endocrine disrupting effect [4]. To the best of our knowledge, current studies on TBBPA include the experimental work on the exposure concentration, toxicity and elimination [5][6][7]. However, theoretical understanding towards the properties of TBBPA is still lacking except thermodynamic property [1] and the establishment of QSAR models [8].…”
