Sonochemical and hydrodynamic cavitation reactors for laccase/hydrogen peroxide...
Gonçalves, Idalina; Martins, Madalena A.; Loureiro, A.; Gomes, A. C.; Paulo, Artur Cavaco; Silva, Carla ManuelaArticle in press ; The main goal of this work is to develop a novel and environmental-friendly technology for cotton bleaching with reduced processing costs. This work exploits a combined laccase–hydrogen peroxide process assisted by ultrasound. For this purpose, specific reactors were studied, namely ultrasonic power generator type K8 (850 kHz) and ultrasonic bath equipment Ultrasonic cleaner USC600TH (45 kHz...
Molecular recognition of esterase plays a major role on the removal of fatty so...
Silva, Carla Manuela; Azoia, Nuno G.; Martins, Madalena A.; Matamá, Maria Teresa; Wu, J.; Paulo, Artur CavacoIn this work it is describe for the first time, the use of an esterase with null activity (Tfu_0883 bacterial cutinase from Thermobifida fusca) on the removal of fat from the surface of a cotton substrate. Similar levels of fat removal were found for both null and wild-type proteins, despite that only wild type protein yielded fatty acids. Our results show that molecular recognition of esterase plays a major ro...
