Technological Advancement Scientific Innovation Bioenergy Research

Researchers from the National Laboratory of the Rockies used super-resolution microscopy and machine learning to study how C. thermocellum bacteria use cellulosome enzyme complexes to degrade biomass. The study provides quantitative data on the movement and distribution of these complexes, which may aid in the development of more efficient consolidated bioprocessing for biofuels and chemicals.
