Abstract :
Esterases play a crucial role in the degradation of phthalic acid esters (PAEs), the common persistent organic pollutants and endocrine disrupting chemicals. However, only a few esterases for PAEs degradation have been characterized. In this study, a novel esterase from Desulfurellaceae bacterium (DeEst) has been identified. We found its hydrolytic activity toward three regioisomers of benzene-dicarboxylic acid esters (i.e., diethyl phthalate, diethyl isophthalate, and diethyl terephthalate). Notably, DeEst is capable of hydrolyzing diethyl phthalate and other PAEs to phthalic acid (PA). The biochemical characterization of DeEst was also investigated. DeEst exhibited strong thermal stability and demonstrated an uncommon thermal activation effect, highlighting its considerable potential for practical applications. |
