The response of the central carbon metabolism of Escherichia coli to temperature-induced recombinant production of human fibroblast growth factor was studied on the level of metabolic fluxes and intracellular metabolite levels. During production, E. coli TG1:plambdaFGFB, carrying a plasmid encoded gene for the recombinant product, revealed stress related(More)
During production in recombinant Escherichia coli, the human basic fibroblast growth factor (hFGF-2) partly aggregates into stable cytoplasmic inclusion bodies. These inclusion bodies additionally contain significant amounts of the heat-shock chaperone DnaK, and putative DnaK substrates such as the elongation factor Tu (ET-Tu) and the metabolic enzymes(More)
The potential of cashew apple juice (CAJ) as a carbon source for oxalic acid (OA) production via fermentation process was investigated in this study. The effects and interactions of CAJ concentration, time, pH, NaNO3 concentration and methanol concentration on OA production were determined in a central composite design (CCD) and the process was modelled and(More)
The effect of high-dose irradiation as a pretreatment method on two common lignocellulosic materials; hardwood (Khaya senegalensis) and softwood (Triplochiton scleroxylon) were investigated by assessing the potential of cellulase enzyme derived from Aspergillus flavus Linn isolate NSPR 101 to hydrolyse the materials. The irradiation strongly affected the(More)
A biosensor for fructose determination was used as basis of an assay for the determination of glucosyltransferase (GTF) activities and applied to monitoring recombinant enzyme production. GTFs catalyze the synthesis of glucans from sucrose leading to the release of fructose. Specific fructose determinations in the microM concentration range were achieved(More)
