Abstract
In this work, A. succinogenes 130Z was used to produce succinic acid from Jerusalem artichoke tuber hydrolysate. Results showed that both fructose and glucose in the tuber hydrolysate were utilized for succinic acid production. The sugar utilization was found to be dependent on process control, hence, when pH was fixed at 6.8 the sugar utilization of fructose was increased from 68.6% to 96.5% and the succinic acid production was also increased by 26.4% to yield 26.8 g/L succinic acid. In this study a one-step pretreatment/hydrolysis method was used where no enzymes were used. Our work suggests that Jerusalem artichoke tubers could be utilized for production of bio-succinic acid.
