TL;DR: The results show that the removal of BDE-209 from wastewater is mainly via biosorption onto aerobic granular sludge, and that aerobic microbial degradation of 4,4′-dibromodiphenyl ether happened with the production of lower BDE congeners.
Abstract: As a new category of persistent organic pollutants, polybrominated diphenyl ethers (PBDEs) have become ubiquitous global environmental contaminants. No literature is available on the aerobic biotransformation of decabromodiphenyl ether (BDE-209). Herein, we investigated the interaction of PBDEs with aerobic granular sludge. The results show that the removal of BDE-209 from wastewater is mainly via biosorption onto aerobic granular sludge. The uptake capacity increased when temperature, contact time, and sludge dosage increased or solution pH dropped. Ionic strength had a negative influence on BDE-209 adsorption. The modified pseudo first-order kinetic model was appropriate to describe the adsorption kinetics. Microbial debromination of BDE-209 did not occur during the first 30 days of operation. Further study found that aerobic microbial degradation of 4,4′-dibromodiphenyl ether happened with the production of lower BDE congeners.

TL;DR: Results revealed the mechanisms of TCs in E2 biodegradation and the performance of a functional strain in estrogen removal in realistic TCs-contaminated aqueous solution and revealed the abundance of pyridine derivatives, which were difficult to decompose over time.

TL;DR: In this article, the bifunctional Sphingonomas sp. strain YK5 that had BPA-degrading and acylhomoserine lactone ( AHL) producing properties was used.

TL;DR: It was found that molecular oxygen is necessary for biodegradation to occur, suggesting an initial oxidative step, and it was proposed that H abstraction from the C-H bond is the first step of TBNPABiodegradation under aerobic conditions, and that the C -H bond cleavage results in the formation of unstable intermediates, which are rapidly debrominated.
