subcritical water hydrolysis of rice straw for Reducing Sugar production with focus on degradation by products and kinetic analysis
Bioresource Technology, 2015Co-Authors: Jun Cheng, Lingkan Ding, Wenlu Song, Feng Qi, Junhu ZhouAbstract:Abstract The competitive reactions of Reducing Sugar production and degradation in the subcritical water hydrolysis of rice straw were investigated to optimise Reducing Sugar yield. The optimised conditions (280 °C, 20 MPa, rice straw concentration of 5 wt.% and agitation speed of 200 rpm) resulted in a Reducing Sugar yield of 0.346 g/g rice straw because of the enhanced Reducing Sugar production and decreased Sugar degradation. The Sugar yield increased when the temperature increased from 250 °C to 280 °C, but it decreased when the temperature further increased to 300 °C because of the degradation of monosaccharides (e.g. glucose and xylose) into by-products (e.g. 2-methyltetrahydrofuran and acetic acid). A first-order reaction model was developed to elucidate the competitive reaction kinetics of Sugar production and degradation at various temperatures. The highest Reducing Sugar yield based on the model was achieved at 280 °C with the highest production and lowest degradation rates.

Conversion of Pyridylamino Sugar Chains to Corresponding Reducing Sugar Chains
Journal of biochemistry, 2003Co-Authors: Chiaki Takahashi, Shin-ichi Nakakita, Sumihiro HaseAbstract:Pyridylamino Sugar chains were converted to the corresponding Reducing Sugar chains by first converting them to 1-amino-1-deoxy derivatives using the method previously reported [S. Hase, J. Biochem. 112, 266-268 (1992)] and then converting the products to the corresponding Reducing Sugar chains using the Sommlet reaction. The reaction conditions were optimized so as to obtain the maximal product yield using 1-amino-1-deoxylactose and 1-amino-1-deoxy-N-acetylglucosamine. When the established procedure was successively applied to pyridylamino high-mannose and complex-type Sugar chains, the corresponding Reducing Sugar chains were obtained in yields of 30%.
