Climate change complicates plant diseases of the future

Human-driven changes in the earth’s atmospheric composition are likely to alter plant diseases of the future. Researchers predict carbon dioxide will reach levels double those of the preindustrial era by the year 2050, complicating agriculture’s need to produce enough food for a rapidly growing population.
University of Illinois researchers are studying the impact of elevated carbon dioxide, elevated ozone and higher atmospheric temperatures on plant diseases that could challenge crops in these changing conditions.
Darin Eastburn, U of I associate professor of crop sciences, evaluated the effects of elevated carbon dioxide and ozone on three economically important soybean diseases under natural field conditions at the soybean-free air-concentrating enrichment (SoyFACE) facility in Urbana.
The diseases downy mildew, Septoria brown …

New method uses electrolyzed water for more efficient fuel production

Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois.
When ethanol is produced, distiller’s dried grain with solubles (DDGS) is a waste product. The DDGS is primarily used as animal feed, but researchers are searching for ways to extract the sugar and ferment it to produce an acetone-butanol-ethanol fuel mix. One obstacle has been in the production phase called pretreatment.
“For any biofuel production you need to have simple sugars such as glucose,” said U of I researcher Hao Feng. The glucose in DDGS is stuck together, forming …
