Ant symbiosis and Biofuels

UW-Madison Communications recently covered a project of the Great Lakes Bioenergy Research Center to sequence the genome of ants that break down and digest cellulose, along with their associated fungi and bacteria ("Sequencing effort to chart ants and their ecosystem").

Recent publications by this project's researchers include:
