Color-sensing yeast could make biofactories more programmable and precise
Baker's yeast is one of biotechnology's most important microorganisms. It has long been used to leaven bread and ferment beer. More recently, advances in synthetic biology have enabled engineered yeast to convert sugar into a wide range of products, including medicines, fuels and industrial chemicals. Yet even well-engineered yeast cells can be difficult to control in a precise and timely way.
