Application

Application Comment Organism
synthesis the immobilization of partially purified hydroxynitrile lyase from Prunus dulcis as crosslinked enzyme aggregate is a very promising tool owing to its ease of preparation, cheapness, and efficiency in the preparation of enantiopure cyanohydrins. Response surface methodology provides an effective way for the optimization of the preparation of PdHNL-crosslinked enzyme aggregate. The synthesis of (R)-mandelonitrile, (R)-2-chloromandelonitrile, (R)-3,4-dihydroxymandelonitrile, (R)-2-hydroxy-4-phenyl butyronitrile, (R)-4-bromomandelonitrile, (R)-4-fluoromandelonitrile, and (R)-4-nitromandelonitrile is achieved with high yield and enantiomeric excess Prunus dulcis
