摘要：

A novel method of coimmobilized whole cells of Pseudomonas reptilivora and Micrococcus glutamicus, entrapped in calcium alginate beads have been used for the production of L-glutamic acid in a single stage fermentation process, using selected production medium enriched with glucose as substrate. The results obtained were compared with the L-glutamic acid production by free cells of Micrococcus glutamicus and by mixed culture of Pseudomonas reptilivora and Micrococcus glutamicus. The yield of glutamic acid obtained with mixed culture is relatively more than that the yield obtained with Micrococcus glutamicus alone. The properties of coimmobilized whole cells of Pseudomonas reptilivora and Micrococcus glutamicus in calcium alginate gel matrix have been investigated thoroughly and compared with those of free cells under most suitable conditions of fermentation.
