| Popis: | Experiments were carried out to assess the utility of coating alginate spheres entrapping biomass with a polyacrylamide resin (Eudragit RL100). The properties studied included mechanical resistance, biomass leakage and mass transfer resistance. In addition bioactivity tests were carried out using entrapped Saccharomyces cerevisiae . The mechanical resistance of the coated beads was higher and the biomass leakage lower than with uncoated controls while the bioactivity and the mass transfer resistance were similar. Coated beads may therefore be of use in bioreactor systems. |
