GONZALEZ, Juan C; ASCENCIO, Adriana P; GONZALEZ-WILLIAMSON, Camila A  and  OSMA, Johann F. Laccase Alginate Encapsulation: Comparison between Assisted and Non-assisted Extrusión for Large-scale Production. rev.ing. [online]. 2013, n.39, pp.24-30. ISSN 0121-4993.

The effect of assisted and non-assisted extrusión 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 extrusión 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.
