Resumo: This paper main objective is to determinate the hydrolysis efficiency by using four different diluted acids treatment: (H2SO4) sulfuric, (HNO3) nitric, phosphoric (H3PO4) and acetic (CH3COOH), in attempt to improve the fibers and bioethanol production levels. In this study twelve Brazilian woods were investigated, including native and exotic species, hardwoods and softwoods. Processes to use wood waste recovery established to produce ethanol and cellulosic fibers simultaneously were carried out. For fermentation essay, a wild line of Saccharomyces cerevisiae yeast was investigated. The incomes related to hydrolysis efficiency, ethanol yields, fibrous fractions efficiency, and plus glucose and delignification levels using acid and alkaline treatments were tested. From the results it is possible to join the production of ethanol and cellulosic fibers simultaneously using wood chips, and due to the complexity of the analyzed material it´s still possible to isolate byproducts. Also from results, the yeast demonstrated to be efficient with an estimate maximum production of 12,94 liters per 100 kg of biomass using Balfourodendron riedelianum specimen and sulfuric acid hydrolysis. All acids and samples demonstrated high and similar efficiency in hydrolysis, indicating that these are feasible for hydrolysis processes use.
