A greater understanding of how plants and microbes work together to store vast amounts of atmospheric carbon in the soil will help in the design of better bioenergy crops for the fight against climate change. Deciphering the mechanics of this mutually beneficial relationship is, however, challenging as conditions in nature are extremely difficult for scientists to replicate in the laboratory. To address this challenge, researchers created fabricated ecosystems or EcoFABs.

Engineered Poplar Lignin Has More of a Valuable “Clip-off” Chemical
Lignin, the complex polymer that gives plants their structural integrity, makes them difficult to break down and creates challenges for the creation of biochemicals and bioproducts. Building blocks that are present in small amounts in the lignin of the bioenergy crop poplar are valuable platform chemicals that are easy to “clip-off” during plant deconstruction. Scientists engineered a new type of poplar to have more of a specific building block in its lignin and less lignin overall. This results in wood that is easier to deconstruct and more valuable as a bioproduct raw material.
