Lacease Alginate Encapsulation: Comparison between Assisted and Non-assisted Extrusion for Large-scale Production

The effect of assisted and non-assisted extrusion for large-scale production on size, shape and biochemical performance of laccase-alginate beads was studied. Results showed that the extruding technique affeets bead size and size distribution but not the shape of the beads. Biochemical characterization showed a similar performance for both extruding methods. However, non-assisted beads presented higher enzymatic activity variability and lower stability in time. Results showed that using the extrusion method, bio-processes are improved by highly homogeneous particulate material facilitating temperature or pH controlled steps. Thus, an assisted method presents several benefits for producing lacease particulate material in large quantities.
