Abstract:
Ziel der Arbeit war die Entwicklung eines biokatalytischen Verfahrenskonzeptes zur Herstellung von als natürlich deklariertem β-Ionon durch regiospezifische oxidative Spaltung von β-Carotin. Als Biokatalysator dienten Carotinoid-spaltende Dioxygenasen. Schwerpunkte der Arbeit: 1. Ermittlung und systematische Untersuchung von Vermittlungsformen für das stark hydrophobe Substrat β-Carotin an das Enzym AtCCD1 in wässrigen Medien 2. Weitere Charakterisierung und verbesserte rekombinante Expression...     »
Translated abstract:
The goal of this work was to develop a biocatalytic process concept for the production of natural-labeled β-ionone by regiospecific oxidative cleavage of β-carotene. The biocatalysts applied were carotenoid cleavage dioxygenases. The core areas of this work were: 1. Determination and systematic investigation of substrate delivery strategies for the highly hydrophobic substrate β-carotene to the enzyme AtCCD1 in an aqueous reaction medium 2. Further characterisation and improved recombinant exp...     »
