Description: Lignocellulosic biomass from the forest industry is a source of bioenergy and renewable feedstock to produce biochemicals compounds through thermochemical, biological, chemical, and physical processes. The present work evaluated two thermochemical pretreatments using sodium hydroxide and ozone as catalyzers to increase the release of monolignols from softwood and hardwood sawdust. In liquid samples, results show that treatments where low concentrations of ozone (0.5 mg/min) were used, sinapyl alcohol (453.7 mg/kg), and coniferyl alcohol (406.5 mg/kg) were the main monolignols with the highest concentration in softwood and hardwood, respectively. Additionally, p-coumaryl alcohol (16.32 mg/kg) was observed only in hardwood samples. On another hand, in solid samples, only p-coumaryl alcohol (19.6 mg/kg) was obtained from hardwood, and sinapyl alcohol (82.6 mg/kg), coniferyl alcohol (102 mg/kg), and p-coumaryl alcohol (4 mg/kg) from softwood. Thus, results show that forestry residues as softwood and hardwood sawdust have enormous potential as feedstock to obtain biochemical compounds with high added value.
