A Biofuel Breakthrough, Courtesy of Fungi

March 22, 2023

It’s a tough job, but someone’s got to do it. In this case, the “job” is the breakdown of lignin, the structural molecule that gives plants strength and rigidity. One of the most abundant terrestrial polymers (large molecules made of repeating subunits called monomers) on Earth, lignin surrounds valuable plant fibers and other molecules that could be converted into biofuels and other commodity chemicals – if we could only get past that rigid plant cell wall.

JGI Researchers Trace the Evolution of Shiitake Mushrooms

February 28, 2023

These fungi are part of the genus Lentinula, which have evolved to decompose hardwoods on every continent besides Europe and Antarctica. Lentinula mushrooms are white rot fungi, belonging to an elite group of decomposers that can break down all of wood’s components — cellulose, hemicellulose, and the toughest molecule, lignin. Understanding Lentinula genomes and their evolution could provide strategies for converting plant waste into sugars for biofuel production.

JGI Looks to Soil to Understand Forest Recovery After Wildfires

October 10, 2022

Within a forest’s soil, a microbiome of bacteria, viruses and fungi process carbon and nitrogen, paving the way for future plants and trees to grow. However, fire changes the microbes within the soil. Recently, JGI collaborators worked to understand which microbes in the soil persist after a wildfire — and why they thrive. Their results appear in Nature Microbiology.
