Sugar Production Efficiency Increased Through Gene Technology
2013-10-17 10:57:01

Aalto University Industry is already making use of rare sugars as low-calorie sweeteners, and as precursors of anti-cancer and antiviral medicines. However, their high cost has impeded research and use: it is not possible to isolate significant amounts of rare sugars directly from nature, and consequently their production has been expensive. The efficiency of sugar production can be increased through gene technology. In her recent doctoral dissertation Anne Usvalampi, Lic.Sc. (Tech.),...

Scientists report in Nature Communications that they have engineered yeast to consume acetic acid, a previously unwanted byproduct of the process of converting plant leaves, stems and other tissues into biofuels. The innovation increases ethanol yield from lignocellulosic sources by about 10 percent. Lignocellulose is the fibrous material that makes up the structural tissues of plants. It is one of the most abundant raw materials on the planet and, because it is rich in carbon it is an...

The researcher in question is Nadia Skorupa Parachin and the secret of her technique is enzymes that she extracted from garden soil. If ethanol can be successfully made from xylose then ethanol production could increase by over 20 per cent "“ to the benefit of cheaper environmentally friendly fuel. Ethanol is manufactured by fermenting sugars from plant material. At present, xylose is not used, despite being the second most common type of sugar found in nature. Succeeding with xylose...

A newly engineered yeast strain can simultaneously consume two types of sugar from plants to produce ethanol, researchers report. The sugars are glucose, a six-carbon sugar that is relatively easy to ferment; and xylose, a five-carbon sugar that has been much more difficult to utilize in ethanol production. The new strain, made by combining, optimizing and adding to earlier advances, reduces or eliminates several major inefficiencies associated with current biofuel production methods. The...

A team of Bioengineers in the United States have modified a strain of bacteria to increase its ability to produce ethanol. The research, published in Biotechnology and Bioengineering, reveals how adaptation and metabolic engineering can be combined for strain improvement, a positive development for the biofuel industry. The team focused their research on Zymomonas mobilis, a bacterium noted for its bio-ethanol producing potential. However, the team believed that ethanol production could be...

Researchers from the Stanford University School of Medicine have identified a gene in the yeast Saccharomyces cerevisiae that might be important for ethanol production from plant material, providing insights into the bioethanol alternative to 'fossil fuels'. Combining new high-throughput genome sequencing technology with traditional genetic methods, this study highlights the previously unknown potential of natural S. cerevisiae strains to convert five-carbon sugars such as xylose into...


Word of the Day
glogg
  • Scandinavian punch made of claret and aquavit with spices and raisins and orange peel and sugar.
This word comes from the Swedish 'glogg,' which is an alteration of 'glodgat,' mulled (wine).
