In der vorliegenden Arbeit wurden zwei Modifikationsverfahren an Eichenholz untersucht. Einerseits wurde Eiche einer HitzeDruck-Dämpfung (engl. heat-pressure steamed HPS) im Autoklaven unterzogen (Druck < 2 bar, Temperatur 120-140 °C), andererseits wurde industriell (mit Ammoniak) gedämpfte Eiche analysiert (bekannt unter dem Begriff Räuchereiche
A micro-reactor coupled to a microfluidic system and an online UV/VIS spectrometer is described. The enzymatic reaction studied is the hydrolysis of the N-benzoyl-L-tyrosine ethyl ester (BTEE) to N-benzoyl-L-tyrosine (BT) and ethanol, catalyzed by chymotrypsin. The production is online monitored with UV spectroscopy at 256 nm. Three different immobilization methods of the enzyme are discussed: Eupergit C, controlled-pore glass (CPG), and Sepharose.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
