3.6. Scanning electron micrograph of co-immobilized gel beads
In co-immobilization gel beads of S. cerevisiae and A. oryzae or
M. purpureus, the gel beads surface (Figs.6a and7a) as well as the inner
bead surface (Figs. 6c and 7c) were smooth before the incubation with
tested microbes. Irregular growth of microorganisms was observed on the outer gel beads surface (Figs. 6b and 7b) or the inner surface(Figs. 6d and 7d) after 13 days of fermentation.
