A research team led by Oak Ridge National Laboratory bioengineered a microbe to efficiently turn waste into itaconic acid, an industrial chemical used in plastics and paints.<\/p>\n

Producing itaconic acid currently involves fungi feeding on relatively pure sugars, which can be expensive. In ORNL’s demonstration, the team used lignin, a waste product from biorefineries and paper mills, to grow the bacterium Pseudomonas putida for potentially cheaper itaconic production.<\/p>\n

The trick was to separate the microbes’ growth phase from itaconic production using dynamic controls. ORNL designed and deployed a biosensor that triggers the metabolic pathway for itaconic acid production only after the microbes consume all the nitrogen that fuels their growth.<\/p>\n

“This technology<\/a> could provide additional revenue for biorefineries by turning lignin into a high-value chemical,” ORNL’s Adam Guss said. “One strain achieved nearly 90% of theoretical yield during the production phase and could be further optimized. We can also app<\/a>ly these methods to a range of carbon waste streams.”<\/p>\n\n
