A hemicellulose (also known as polyose) is one of a number of heteropolymers (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all terrestrial plant cell walls. Cellulose is crystalline, strong, and resistant to hydrolysis. Hemicelluloses are branched, shorter in length than cellulose, and also show a propensity to crystallize. They can be hydrolyzed by dilute acid or b… Web7 mei 2013 · Batch fermentation of non-detoxified sugarcane bagasse hemicellulose hydrolysate was conducted to produce succinic acid by A. succinogenes NJ113 in a 3-L stirred bioreactor with an initial sugar concentration of 30 g/L containing 22.4 g/L xylose, 3.6 g/L glucose, and 3.9 g/L arabinose.
