Kinetic study and modelling on L-arginine fermentation.
The batch fermentation of L-arginine using Corynebacterium crenatum L-arginine-producing mutant 971.1 was kinetically studied in a 2.6 L fermentor for the following purposes: kinetic classification of L-arginine fermentation by the comparison of the two-phases of specific growth rates; modelling of the L-arginine fermentation, and discussion about the effects of oxygen supply on the conversion rate of glucose to L-arginine, by comparing the fraction of glucose-consumption for L-arginine-formation alpha p and the fraction of glucose-consumption for cell-growth alpha x under different oxygen transfer coefficients kLa. The kinetic fermentative behavior of the strain 971.1 in L-arginine formation, which was related to the velocity and effectiveness of the metabolism of the cell, was mathematically analyzed.
