C. glutamicum metabolism

 

Corynebacterium glutamicum, a soil bacterium, is used to produce amino acids such as lysine and glutamate. C. glutamicum is often exposed to osmolality changes in its medium, and the bacterium has therefore evolved several adaptive response mechanisms to overcome them. We have quantified the metabolic response of C. glutamicum under osmotic stress using elementary mode analysis (EMA). Further, we have obtained the optimal phenotypic space for the synthesis of lysine and formation of biomass.
