Fermentation of lactose to ethanol in cheese whey permeate and concentrated permeate by engineered Escherichia coli
BACKGROUND Whey permeate is a lactose-rich effluent remaining after protein extraction from milk-resulting cheese whey, an abundant dairy waste. The lactose to ethanol fermentation can complete whey valorization chain by decreasing dairy waste polluting potential, due to its nutritional load, and producing a biofuel from renewable source at the same time. Wild type and engineered microorganisms...
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....
متن کاملEnhanced Expression of Recombinant Activin A in Escherichia coli by Optimization of Induction Parameters
Activin A is a member of the transforming growth factor β super family. Because of its extensive clinical usages, its recombinant production is beneficial. In this study, activin A was expressed in E. coli using the pET 21a expression vector. The optimization of the activin A production in E. coli was done by using the response surface methodology (RSM). At this stage, the effect of IPTG and la...
متن کاملHydrogen production by recombinant Escherichia coli strains
The production of hydrogen via microbial biotechnology is an active field of research. Given its ease of manipulation, the best-studied bacterium Escherichia coli has become a workhorse for enhanced hydrogen production through metabolic engineering, heterologous gene expression, adaptive evolution, and protein engineering. Herein, the utility of E. coli strains to produce hydrogen, via native h...
متن کاملCheese whey-induced high-cell-density production of recombinant proteins in Escherichia coli
BACKGROUND: Use of lactose-rich concentrates from dairy processes for the induction of recombinant gene's expression has not received much attention although they are interesting low cost substrates for production of recombinant enzymes. Applicability of dairy waste for induction of recombinant genes in Escherichia coli was studied. Clones expressing Lactobacillus phage muramidase and Lactobaci...
