- Microencapsulation of a recombinant aminopeptidase (PepN) from Lactobacillus rhamnosus S93 in chitosan-coated alginate beadsSorayya Azarnia
Department of Food Science and Agricultural Chemistry, McGill University, Ste Anne de Bellevue, QC, Canada
J Microencapsul 25:46-58. 2008..Increasing the CaCl2 concentration over 0.1 M neither affected the EE nor the ER. Increasing hardening time beyond 10 min led to a decrease in EE and the alginate:enzyme ratio (3 : 1) was optimal to prevent the ER...
