Metabolic engineering for improved microbial pentose fermentation.
Global concern over the depletion of fossil fuel reserves, and the detrimental impact that combustion of these materials has on the environment, is focusing attention on initiatives to create sustainable approaches for the production and use of biofuels from various biomass substrates. The development of a low-cost, safe and eco-friendly process for the utilization of renewable resources to gen...
متن کاملMetabolic engineering for improved fermentation of pentoses by yeasts
The fermentation of xylose is essential for the bioconversion of lignocellulose to fuels and chemicals, but wild-type strains of Saccharomyces cerevisiae do not metabolize xylose, so researchers have engineered xylose metabolism in this yeast. Glucose transporters mediate xylose uptake, but no transporter specific for xylose has yet been identified. Over-expressing genes for aldose (xylose) red...
متن کاملEngineering of Saccharomyces cerevisiae for efficient anaerobic alcoholic fermentation of L-arabinose.
For cost-effective and efficient ethanol production from lignocellulosic fractions of plant biomass, the conversion of not only major constituents, such as glucose and xylose, but also less predominant sugars, such as l-arabinose, is required. Wild-type strains of Saccharomyces cerevisiae, the organism used in industrial ethanol production, cannot ferment xylose and arabinose. Although metaboli...
متن کاملImprovement of L-Arabinose Fermentation by Modifying the Metabolic Pathway and Transport in Saccharomyces cerevisiae
The L-arabinose utilization pathway was established in Saccharomyces cerevisiae, by expressing the codon-optimized araA, araB, and araD genes of Lactobacillus plantarum. After overexpressing the TAL1, TKL1, RPE1, RKI1, and GAL2 genes and adaptive evolution, the L-arabinose utilization of the recombinant strain became efficient. The resulting strain displayed a maximum specific growth rate of 0....
متن کاملMetabolic Engineering of Yeast for Xylose Uptake and Fermentation
Fuel ethanol production from plant biomass hydrolysates by the baker’s yeast Saccharomyces cerevisiae is of great economic and environmental significance. Costeffective production of ethanol from plant biomass should not only be based on the readily fermentable starch and sucrose fractions of plant carbohydrates, but also on the much more resistant lignocellulosic fractions. The utilization of ...
