Resumo

The growing concern on the fate of toxic and persistent micropollutants in aquatic ecosystems led to the need to comprehend how these substances can be converted into less harmful chemicals. Tetrabromobisphenol A (TBBPA) is the most used brominated flame retardant (BFR) worldwide and is often detected in water bodies and wastewaters. In the past 20 years, the degradation of TBBPA has been investigated in bioreactors with different microbial communities and under a variety of operational parameters. Comprehending TBBPA biodegradation contributes to a better understanding of other flame retardants environmental fate and the optimization of wastewater treatment biotechnologies. Even though many process-optimization procedures and investigations on mixed and isolated strain functions have been conducted, understanding metabolic processes on this micropollutant breakdown remains uncovered, especially in environmental settings. Different findings on how to optimize TBBPA bioconversion and the factors influencing cometabolic and metabolic reactions may mislead further studies or suggest arguable directions. For this reason, this review summarizes and critically discusses how the main environmental and operational parameters affect TBBPA biodegradation, the main degradation pathways and subproducts, and the microorganisms and enzymatic activities involved in this process, raising some questions that should be addressed in more in-depth studies.
