additional information
-
After 24 h of catalytic activity the immobilized biocatalyst Sepabeads EC-EA/BFD showed a remaining activity of 5% of its initial value.
additional information
-
specific activity of around 62 U/g dry carrier. The activity is determined for the reaction of acetaldehyde (500 mM) and benzaldehyde (50 mM) at pH 8.0
additional information
-
Stability of Sepabeads EC-EA/BFD is determined by repetitive batch experiments while carrying out the synthesis of 2-hydroxy-1-phenylpropanone. The reaction of benzaldehyde and acetaldehyde is carried out at 30°C and after each batch is washed. The decrease of the initial reaction rate is followed for six batches. The newly prepared biocatalyst (enzyme loading 320 mg/g) shows an initial reaction rate of 130 U/g carrier with respect to the C-C-coupling reaction, whereby the rate decreases down to 10% (13 U/g) in the sixth batch.
