Abstract
The effective production of xylooligosaccharides (XOs) from rice straw was
investigated. Rice straw contains rich hemicellulose which can be hydrolyzed
by enzyme; the XOs were obtained under hydrothermal conditions. To improve
the productivity of XOs, ultrafiltration was chosen to eliminate xylan in the
XOs. Under optimum hydrolysis conditions (1000 IU enzyme/g, 35 0C, 10%
substrate concentration, pH 6.5, 6 h), the DP was the lowest. After
ultrafiltration, xylan was eliminated. On the basis of experimental data, an
industrial XO production process consisting of pretreatment, enzymatic
treatment and purification was designed. Using the designed process, 2.9g dry
of purified XO was produced from 50g dry rice straw power.
