Succinic acid production by Anaerobiospirillum succiniciproducens ATCC 29305 growing on galactose, galactose/glucose, and galactose/lactose.

摘要: Succinic acid-producing Anaerobiospirillum succiniciproducens was anaerobically grown on galactose, galactose/glucose, or galactose/lactose in order to study its galactose fermentation. Unlike a previous report, A. found efficiently metabolize as the sole carbon source at rate of 2.4 g/g-DCW/h and produced succinic acid with high yield 87% using glucose. When glucose were present, metabolized both sugars simultaneously. Furthermore, when lactose coexisted, did not inhibit fermentation succiniciproducens. Therefore, co-utilization other can improve productivity economy bio-based processes.
