- Citric waste saccharification under different chemical treatments Carlos Eduardo de Farias Silva Georgia Nayane Silva Belo Gois Lívia Manuela Oliveira da Silva Renata Maria Rosas Garcia Almeida Ana Karla de Souza Abud Ingeniería orange biomass Pretreatment expe rimental design Second generation ethanol from lignocellulose materials has been used in applications for food processing wastes. Since Brazil has a leading position in orange juice exports, the influence of acid and alkali pretreatments on liquor saccharification, solubilization of solid fraction and mass yield was evaluated. Time and C acid or C alkaline at different concentrations of solids (low to moderate, 1 to 9%) and high catalyst concentrations were analyzed. A hydrothermal pretre atment was conducted under the same conditions of acid and alkaline treatments to investigate the relative selectivity increase in using the catalysts. The chemical analyses of wastes indicated a 70% total carb ohydrate level denoting a promising raw material for bioethanol production. Pretreatment caused acid saccharifications between 25 and 65% in total reducing sugars (TRS) and mass yields (MY) between 30 and 40% . In alkaline pretreatment, these rates ranged between 2 and 22.5% and between 30 and 80, respective ly. In hydrothermal pretreatment, solubilized TRS varied between 3 and 37%, whereas MY rema ined between 45 and 60%, respectively. C biomass strongly influenced the three variables; in the same way, time affected MY. 2015 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303241625010 en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
