Actinobacillus succinogenes ATCC 55618 Fermentation Medium Optimization for the Production of Succinic Acid by Response Surface Methodology
As a potential intermediary feedstock, succinic acid takes an important place in bulk chemical productions. For the first time, a method combining Plackett-Burman design (PBD), steepest ascent method (SA), and Box-Behnken design (BBD) was developed to optimize Actinobacillus succinogenes ATCC 55618 fermentation medium. First, glucose, yeast extract, and MgCO(3) were identified to be key medium ...
متن کاملSuccinic 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 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 کاملSignificance of CO2 donor on the production of succinic acid by Actinobacillus succinogenes ATCC 55618
BACKGROUND Succinic acid is a building-block chemical which could be used as the precursor of many industrial products. The dissolved CO2 concentration in the fermentation broth could strongly regulate the metabolic flux of carbon and the activity of phosphoenolpyruvate (PEP) carboxykinase, which are the important committed steps for the biosynthesis of succinic acid by Actinobacillus succinoge...
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...
