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.),...

Finding renewable and economic sources of energy are one of the most important concerns for the continuation of the human species. New research, published in BioMed Central's open access journal Biotechnology for Biofuels, has produced a novel strain of yeast with improved xylose tolerance and metabolism, and consequently improved ethanol production. Bioethanol is considered one of cleanest renewable replacements for fossil fuel. However using glucose from crops, such as sugar cane or...

Research published in the journal GENETICS identifies new genes that improve ethanol tolerance in yeast cells, with the goal of generating higher ethanol concentrations for biofuel production. An effort to increase biofuel production has led scientists to discover genes in yeast that improve their tolerance to ethanol, allowing them to produce more ethanol from the same amount of nutrients. This study, published in the December 2010 issue of GENETICS, shows how genetically altered yeast cells...

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
penuche
  • A fudgelike confection of brown sugar, cream or milk, and chopped nuts.
'Penuche' is a variant of 'panocha,' a coarse grade of sugar made in Mexico. 'Panocha' probably comes from the Spanish 'panoja, panocha,' ear of grain.
