Researchers at the University of Campinas (UNICAMP), working in partnership with colleagues at the Brazilian Biorenewables National Laboratory (LNBR) in Campinas, São Paulo State, Brazil, have discovered that modifying the enzyme β-glucosidase sourced from Trichoderma harzianum, a fungus found in the Amazon, greatly facilitates the hydrolysis of cellulosic feedstocks for the production of simple sugars for subsequent fermentation.
