Abstract
In this study, the structural modification of Siam weed (Chromolaena odorata) was performed using NaOH–H2O2- and Ca(OH)2–H2O2-based oxidative pretreatment for the enzymatic conversion of the biomas...

The potential of biomass energy as an alternative to fossil-based energy sources for fuels and chemicals production is very huge
Comparing with Ayeni et al (2014b), this study showed a higher reducing sugar (RS) obtained at pretreatment conditions of 70°C, time 3 h, and 1%H2O2, than at 50°C, time 4 h, and 1%H2O2
The study evaluated the feasibility of using APO pretreatment methods namely, sodium hydroxide– hydrogen peroxide enhanced pretreatment (SHP) and calcium hydroxide–hydrogen peroxide enhanced pretreatment (CHP), to deconstruct Siam weed towards its bioconversion to RS
Summary
The potential of biomass energy as an alternative to fossil-based energy sources for fuels and chemicals production is very huge. Production of biocommodities from biomass could be an attractive alternative to disposal of these residues (Wyman, 2001) Utilization of these waste materials is very important as there is reduction in the overdependency on fossil fuels that degrade our environment. Lignocelluloses mainly consist of cellulose, hemicelluloses, and lignin which are bonded together by covalent bonding, various intermolecular bridges, and van der Waals’ forces forming a complex structure, making it resistant to enzymatic hydrolysis and insoluble in water (Ayeni et al, 2018; O’Sullivan, 1997) These polysaccharides (cellulose and hemicelluloses) and lignin in lignocelluloses are useful precursors in producing fuels and chemicals such as ethanol, butanol, succinic acid, furfural, energy as electricity, etc. Hydrogen peroxide and alkaline oxidative pretreatment (alkaline peroxide oxidation (APO)) is known to decrystallize cellulose (Gould, 1984)
