Succinic acid production with reduced by-product formation in the fermentation of Anaerobiospirillum succiniciproducens using glycerol as a carbon source. Succinic acid(cas:110-15-6) was produced by fermentation of Anaerobiospirillum succiniciproducens using glycerol as a carbon source. When cells were anaerobically cultured in a medium containing 6.5 g/L glycerol, a high succinic acid(cas:110-15-6) yield (133%) was obtained while avoiding the formation of by-product acetic acid.


The gram ratio of succinic acid(cas:110-15-6) to acetic acid was 25.8:1, which is 6.5 times higher than that obtained using glucose (ca. 4:1) as a carbon source. Therefore, succinic acid(cas:110-15-6) can be produced with much less by-product formation by using glycerol as a carbon source, which will facilitate its purification. When glucose and glycerol were cofermented with the increasing ratio of glucose to glycerol, the gram ratio of succinic acid to acetic acid and succinic acid(cas:110-15-6) yield decreased, suggesting that glucose enhanced acetic acid formation irrespective of the presence of glycerol. Glycerol consumption by A. succiniciproducens required unidentified nutritional components present in yeast extract.


By intermittently feeding yeast extract along with glycerol, a high succinic acid(cas:110-15-6) yield (160%) could be obtained while still avoiding acetic acid formation. This resulted in the highest ratio of succinic acid(cas:110-15-6) to acetic acid (31.7:1). Copyright 2001 John Wiley & Sons, Inc.
