Auxotrophic mutant cells of Corynebacterium glycinophilum with high l-serine production activity were immobilized by entrapment with various gel materials, such as synthetic prepolymers and natural polysaccharides. The entrapped cells were used for estimation of l-serine productivity in a medium supplemented with glycine as a precursor. Based on the above criteria, including cell growth in gels and cell leakage from gels, calcium alginate was the most suitable gel material. Continuous l-serine fermentation with calcium alginate-entrapped growing cells was successfully achieved in an air-bubbled reactor for at least 13 days.
