Succinic acid production on xylose-enriched biorefinery streams by Actinobacillus succinogenes in batch fermentation
BACKGROUND Co-production of chemicals from lignocellulosic biomass alongside fuels holds promise for improving the economic outlook of integrated biorefineries. In current biochemical conversion processes that use thermochemical pretreatment and enzymatic hydrolysis, fractionation of hemicellulose-derived and cellulose-derived sugar streams is possible using hydrothermal or dilute acid pretreat...
متن کاملContinuous succinic acid production by Actinobacillus succinogenes on xylose-enriched hydrolysate
BACKGROUND Bio-manufacturing of high-value chemicals in parallel to renewable biofuels has the potential to dramatically improve the overall economic landscape of integrated lignocellulosic biorefineries. However, this will require the generation of carbohydrate streams from lignocellulose in a form suitable for efficient microbial conversion and downstream processing appropriate to the desired...
متن کاملIsolation of NH₄+-tolerant mutants of Actinobacillus succinogenes for succinic acid production by continuous selection.
Actinobacillus succinogenes, a typical succinic acid producing microorganism, was inhibited seriously by ammonium ion, which hampered industrialization of A. succinogenes with ammonium ion based material as the pH controller. In this study, we have isolated an ammonium ion-tolerant mutant of A. succinogenes by continuous-culture technique in which all environmental factors beside the stress (am...
متن کاملMETABOLIC CAPABILITIES OF Actinobacillus succinogenes FOR SUCCINIC ACID PRODUCTION
Attention has been focused on microbial succinic acid production as an alternative for conventional chemical synthesis that is associated with environmental pollution. A metabolic model for Actinobacillus succinogenes 130Z was developed with a mixture of glucose and xylose as substrate. The metabolic fluxes during succinicate production were determined using flux balance analysis by linear prog...
متن کاملContinuous succinic acid fermentation by Escherichia coli
High cell densities were obtained by separating the cells with an external hollow fibre filter. Extreme product inhibition at high succinate titres resulted in cell death and subsequent lysis. Accordingly, the highest succinate titre obtained during continuous fermentation was 25 g.L at a dilution rate of 0.05 h. The highest volumetric productivity of 3 g.L.h and the highest succinate yield (0....
