| Abstract | Rice residues (RRs) are classified as an agricultural waste, which refer to rice bran, rice husk and rice straw. In the present study, the chemical compositions of each RRs were analyzed. The determination of lignocellulosic compositions of rice bran was revealed and represented as an outstanding biomass that consisted of high cellulose and low hemicellulose and lignin. While the compositions of rice husk and rice straw was obviously contrasted from rice bran. Furthermore, the acid-alkaline pretreatment of RRs under autoclaving at 121 ?C for 90 min was investigated for determination of the reducing sugar yield and lignocellulosic compositions change. The study consists of four pretreatment conditions for disruption of RRs structure with different solutions, including the condition (1): 1%(v/v) H2SO4, (2): 1%(w/v) NaOH, (3): 1%(w/v) NaOH following by 1%(v/v) H2SO4, and (4): distilled water (control). The result showed that the acid pretreatment with 1%(v/v) H2SO4 solution (condition 1) was the best condition that provided the highest reducing sugar yield from all RRs kinds. The dilute acid and alkaline pretreatment of RRs under 121 ?C for 90 min illustrated a clearly variation of its lignocellulosic compositions. The acid pretreated rice bran showed that cellulose reduction which correlated with concentration of reducing sugar yield released in the same experiment condition |
