• Resumen

  • The objective of this work was to assess the utility of the Ammonia Pressurization and Depressurization (PDA) process to enhance the enzymatic production of reducing sugars from rice straw (RS). Two experiments were carried out in duplicate. The first experiment involved a 20 min-treatment time and three moisture levels (15, 35 and 60 %). In the second experiment, three treatment times (0, 6 and 20 min) were tested with 35 % moisture-samples. NDF, ADF and ADL were determined in quadruplicate in the samples to estimate solubles, cellulose, hemicellulose and lignin. Samples were subjected to enzymatic hydrolysis by cellulase, cellobiase and hemicellulase (5 IU/g DM, 28.4 CBU/g and 2.5 mg/g, respectively). The ammonia treatment significantly increased solubles content of rice straw (P
