General Stability | Organism |
---|---|
The stability of Sepabeads EC-EP-CALB is investigated within the solvent-free system polyglycerol+lauric acid. The limiting factor of this system is its high viscosity and the different polarities of the starting materials. This causes a two phase system, whereby the detergent form formed as a product accounts for some leaching of the biocatalyst. These are challenges for the optimized use of the prepared biocatalyst. Using it in a repetitive batch mode gives information about the stability in the esterification reaction. The initial reaction rate is found to be 500 U/g and decreases within eight batches to 130 U/g. | Moesziomyces antarcticus |

additional information | Moesziomyces antarcticus | The conversion of the lauric acid is at 80% after 4 h whereas the residual amount of polyglycerol is at 50% at this time. The conversion of polyglycerol remains lower than the conversion of lauric acid, because of the multiple hydroxy functions within the mixture of different glycerol oligomers. The equilibrium of the reaction can be shifted to total conversion by removal of water applying vacuum to the stirred tank reactor. | ? | - |
