Researchers at the University of Virginia have uncovered how plant cells produce cellulose fibers, a finding that could lead to more efficient bio-ethanol production. The study mapped out the structure of the enzyme that manufactures cellulose to reveal a snapshot of cellulose synthesis by plants. "Understanding how cellulose microfibrils are being formed might allow us to design/engineer plants with optimized cell walls for biofuel production," one of the researchers said.
