Recent Findings from South China University of Technology Has Provided New Information about Bioresources (Hot Water Extraction of Corn Stover: Hemicellulose Fractionation and its Effect on Subsequent Soda-AQ Pulping)

By a News Reporter-Staff News Editor at Life Science Weekly -- Fresh data on Life Science Research are presented in a new report. According to news reporting out of Guangdong, People's Republic of China, by NewsRx editors, research stated, "Fractionation of lignocellulosic biomass is an important process in producing biofuels. In this study, hot water extraction of corn stover hemicellulose was carried out at 150, 160, and 170 degrees C. Variations of sugar content in the hydrolysate under different holding time were detected."

Our news journalists obtained a quote from the research from the South China University of Technology, "The contents of furfural and 5-hydroxymethyl-2-furaldehyde generated during the extraction were also determined. Results showed that the main composition of the hydrolysate was xylo-oligosaccharide; the yield of oligosaccharides first increased as holding time was prolonged. After extraction at 160 degrees C for 210 min, 70.2% of the total xylan was dissolved, with the generation of furfural (0.90 g/L) and 5-hydroxymethyl-2-furaldehyde (0.10 g/L). The effects of extraction on alkali pulping and bleaching were also investigated."

According to the news editors, the research concluded: "Results indicated that soda-AQ pulp obtained from the extracted material had poorer tensile and burst strengths but better tear strength."
