Although natural yeast fermentation
produces isobutanol, it does so in miniscule amounts.
In between they turned the light off to shift their metabolism from powering growth to
producing isobutanol.

Using their new technique, the Princeton researchers have now used fermentation and genetically - engineered yeast to
produce other chemicals including lactic acid, used in food production and bioplastics, and
isobutanol, a commodity chemical and an advanced biofuel.
In one case, turning on and off a blue light caused the special yeast to alternate between
producing ethanol, a product of normal fermentation, and
isobutanol, a chemical that normally would kill yeast at sufficiently high concentration.
They managed to suppress the yeast's evolutionary self - interest by genetically engineering it to
produce large quantities of
isobutanol.
A team of researchers at Princeton University has developed a way to cause yeast to
produce more
isobutanol, a possible candidate for use as a biofuel.
