At 25 billion gal produced globally each year, ethanol has made a crucial contribution to transportation fuel supplies. But without much effort, a few tweaks to yeasts and the reaction conditions they operate under could boost ethanol production further and reduce costs, according to two research reports.

Both approaches address ethanol production’s biggest problems: Yeasts used to ferment sugars into alcohols become easily overheated and inebriated. Yeasts are sensitive to the high temperatures they generate . . .
