Abstract
Bamboo plants are plants that can grow quickly and easily, and is an abundant and renewable resource plants analogous to deciduous tree and conifer. In this study, bamboo species of Yushania alpina was pretreated with sodium hydroxide (NaOH) and hydrolyzed by dilute sulfuric acid to produce reducing sugar. Phenol-sulphur acid method was used to determine the response. Seventeen experimental runs were carried out at temperature range (110-128oC), concentration of H2SO4 range of (1-7%) and residence time range of (30-60 min) respectively. The effect of the parameters was measured by concentration of reducing sugar produced for each, and the optimization of glucose production was done by using Box-Behnken design methodology. The results reveal that, the temperature, concentration and time significantly affected the glucose production. At range of low temperature, concentration and time, the yield was decreased while at high value of factors the yield of reducing sugar increased. At 113.17oC, 3.43wt%, 33.65min and desirability of 0.71 the optimum reducing sugar of 19.9 found.
Highlights
Production processes based on renewable resources has become one of the most important concerns of today, especially due to the depletion of non-renewable resources such as petroleum
The production process of monosaccharaides from lignocellulosic biomass was effective through optimization of independent variables
The current study indicates that Response surface methodology (RSM) with engaging Box-Behnken Design (BBD) has provided a consistent and precise procedure in optimizing the reducing sugar production from the bamboo species Yushania alpina
Summary
Production processes based on renewable resources has become one of the most important concerns of today, especially due to the depletion of non-renewable resources such as petroleum. The significant reduction in fossil-based resources containing petroleum, natural gas as well as coal, and conservational anxieties linked to the consumption of these resources, has led to attention more and more on renewable raw materials. It is known that plantbased raw materials and lingo cellulosic biomass have the prospective to exchange a major part of fossil-based resources for the manufacturing production of energy, chemicals, and materials. Bamboo is a hopeful class for use as a feedstock in a biorefinery for the fabrication of pulp, bioethanol, and other chemicals because of numerous reasons. It not single matures profligate and has a dissimilar chemical composition, short renovation, and easy propagation
