Barley is a potential alternative feedstock for ethanol production since its by-product is a nutritious feed. The team of Gongshe Hu from USDA Agricultural Research Service tested a barley mutant, m351, possessing a lower beta-glucan content, for its ethanol production efficiency and feed fraction quality.

Grain samples from m351 were used for ethanol production and produced the same amount of ethanol as the wild types. However, the feed fraction derived from the fermentation process of the m351 mutant showed 5% more protein and 7% less beta-glucan than that from the wild type, indicating more valuable feed fraction from m351.

The experiment provided evidence that m351 is a useful genetic resource for developing barley cultivars for use in bioethanol and feed production.
