A bacterial energy storage system is modified to make polymers.
This week brings some progress on the other side of the equation, with a team of Korean researchers describing how they've engineered a bacterial strain that can make a useful polymer starting with nothing but glucose as fuel. The system they developed is based on an enzyme that the bacteria use when they're facing unusual nutritional conditions, and it can be tweaked to make a wide range of polymers. These chemicals are formed when the bacterial cells continue to have a good supply of carbon sources and energy, but they lack some other key nutrients needed to grow and divide.
