Abstract The thermal stability of an immobilization technique using a pellicular latex matrix was examined in a packed-bed column reactor. The stability was found to vary with liquid flow rate, the type of latex, temperature of operation, and the amount of yeast cells. Adjusting these parameters and introducing particulate inorganic fillers strengthened the latex matrix and improved the thermal stability. Optimization of this immobilization technique resulted in a procedure that allowed latex polymers to be mechanically stable at temperatures up to 50°C. The biological viability of this improved immobilization scheme was demonstrated through the production of L-aspartic acid by immobilized cells of E. coli.
