Abstract

Lactic acid was produced by immobilizedLactobacillus delbreückii cells in a fixedbed reactor and then separated by a column packed with poly(4-vinylpyridine) as an adsorbent. Satisfactory simulation results were obtained by describing the fermentation process using a fermentation kinetics model with axial dispersion and the column adsorption process using a linear-driving-force model.
