In this study, Actinobacillus succinogenes NJ113 microbial electrolysis cells (MECs) were used to enhance the reducing power responsible for succinic acid production from corncob hydrolysate. During corncob hydrolysate fermentation, electric MECs resulted in a 1.31-fold increase in succinic acid production and a 1.33-fold increase in the reducing power(More)
Efficient biosynthesis of succinate from a renewable biomass resource by engineered Escherichia coli is reported in this paper. Fermentation of sugarcane bagasse hydrolysate by engineered E. coli BA204, a pflB, ldhA, and ppc deletion strain overexpressing the ATP-forming phosphoenolpyruvate carboxykinase from Bacillus subtilis 168, produced a final(More)
The development of efficient microbial processes for pinocembrin production has attracted considerable attention. However, pinocembrin biosynthetic efficiency is greatly limited by the low availability of the malonyl-CoA cofactor in Escherichia coli. Fatty acid biosynthesis is the only metabolic process in E. coli that consumes malonyl-CoA; therefore, we(More)
Although the routes of de novo pyridoxal 5'-phosphate (PLP) biosynthesis have been well described, studies of the engineering of an intracellular PLP supply are limited, and the effects of cellular PLP levels on PLP-dependent enzyme-based whole-cell biocatalyst activity have not been described. To investigate the effects of PLP cofactor availability on(More)
The effect of fusing the PelB signal sequence to lysine/cadaverine antiporter (CadB) on the bioconversion of l-lysine to cadaverine was investigated. To construct a whole-cell biocatalyst for cadaverine production, four expression plasmids were constructed for the co-expression of lysine decarboxylase (CadA) and lysine/cadaverine antiporter (CadB) in(More)
