Glutamic Acid Production Bio-Synthesis Process Quiz

Corynebacterium glutamicum and Brevibacterium divericartum

Fed batch fermentation is preferred because most amino acid production requires high sugar concentration, and adding all sugar at once can inhibit growth of microorganisms and reduce yield.

Production of glutamic acid is greatest when biotin is limited, i.e., suboptimal.
