Kinetic study of organic acid formations and growth of Anaerobiospirillum succiniciproducens during continuous cultures.
Succinic acid-producing Anaerobiospirillum succiniciproducens was anaerobically grown in glucose-fed continuous cultures using glucose as a carbon source, and the metabolic flexibility of A. succiniciproducens in response to varying glucose concentrations and dilution rates was examined. Both succinic acid (SA) and acetic acid (AA) formation was growth-associated, and their growth-rate-related coefficients (KSA/X, KAA/X) and nongrowth-rate-related coefficients (K'SA/X, K'AA/X) were slightly influenced by glucose concentrations. A high glucose concentration (38 g/l) and high growth rate (0.63 h-1) did not induce by-product formation.
