James Steele’s new company, Lactic Solutions, is advancing a judo-like remedy: using genetic engineering to transform enemy into friend.
The findings are important as yeasts are critical to many industries — brewing, fermenting other foods, making drugs like human insulin, and producing new biofuels.
"We get two for the price of one," says researcher Shannon Stahl, "and we can save half a volt ... In a fuel cell, that is significant saving of energy."
