Enzyme-Catalyzed Oxidation of 17β-Estradiol Using Immobilized Laccase from Trametes versicolor
Many natural and synthetic estrogens are amenable to oxidation through the catalytic action of oxidative enzymes such as the fungal laccase Trametes versicolor. This study focused on characterizing the conversion of estradiol (E(2)) using laccase that had been immobilized by covalent bonding onto silica beads contained in a bench-scale continuous-flow packed bed reactor. Conversion of E(2) acco...
متن کاملThe immobilization of laccase enzyme from Trametes versicolor on the surface of porous zinc oxide nanoparticles and studying features of the immobilized enzyme
The laccase enzyme is the largest group of Oxidoreductase enzymes and is capable of oxidizing a wide range of organic substrates to water along with molecular oxygen resuscitation. ZnO nanoparticles are known for their specific properties such as chemical stability, high electrochemical coupling rates, and wide range of absorption of radiation as multifunctional compounds. In this study, ZnO po...
متن کاملUltrasound-intensified laccase production from Trametes versicolor.
An efficient intermittent ultrasonic treatment strategy was developed to improve laccase production from Trametes versicolor mycelia cultures. The optimized strategy consisted of exposing 2-day-old mycelia cultures to 5-min ultrasonic treatments for two times with a 12-h interval at the fixed ultrasonic power and frequency (120 W, 40 kHz). After 5 days of culture, this strategy produced the hig...
متن کاملOxidation of Endocrine Disrupting Chemical by Trametes versicolor Laccase
There is longstanding environmental concern regarding endocrine disrupting chemicals and wastewater treatment facilities’ inability to remove them. Estrogens in particular, including 17 β-estradiol, 17 α-ethynylestradiol, and bis-phenol A, have been reported to depress cortisol levels and cause development of intersexual gonads in fish, along with various additional disruptions to the endocrine...
