Continuous succinic acid fermentation by Actinobacillus succinogenes in a packed-bed biofilm reactor.

ABSTRACT:

Background

Succinic acid is one of the most interesting platform chemicals that can be produced in a biorefinery approach. In this study, continuous succinic acid production by Actinobacillus succinogenes fermentation in a packed-bed biofilm reactor (PBBR) was investigated.

Results

The effects of the operating conditions tested, dilution rate (D), and medium composition (mixture of glucose, xylose, and arabinose-that simulate the composition of a lignocellulosic hydrolysate)-on the PBBR performances were investigated. The maximum succinic acid productivity of 35.0 g L^-1 h^-1 and the maximum SA concentration were achieved at a D = 1.9 h^-1. The effect of HMF and furfural on succinic acid production was also investigated. HMF result
