3.1. Characterization of pAAm-Sc capsules
A series of polymeric hydrogels based on polyacrylamide matrix were used for entrapment of S. cerevisiae. Polyacrylamide hydrogel without yeast was used as a control system. The SEM micrograph of entrapped S. cerevisiae pAAm-Sc and the pAAm hydrogel are presented in Fig. 1.
