WebIn this work, high cell density fermentation was investigated for succinic acid production by a metabolically engineered strain SD121 with ldhA, pflB, ptsG mutation and … WebHigh cell density fermentation (HCDF) is widely used to provide a high level of productivity to derive proteins or cells. For these cultures the oxygenation capacity of conventional bioreactors like stirred tanks or bubble columns is rapidly exhausted. The dissolved oxygen concentration usually becomes limiting for microbial growth.
