Heterologous expression and characterization of a xylanase and xylosidase from white rot fungi and their application in synergistic hydrolysis of lignocellulose.

Chemosphere 2018 Dec 14;212:24-33. Epub 2018 Aug 14.

Key Laboratory of Molecular Biophysics of MOE, College of Life Science and Technology, Huazhong University of Science and Technology, Wuhan 430074, PR China. Electronic address:

Endo-xylanase and β-xylosidase are the major enzymes for hemicellulose hydrolysis, which play a significant role in biomass conversion. In our previous work, the white-rot fungi Pleurotus ostreatus HAUCC 162 and Irpex lacteus CD2 were demonstrated to have strong ability in lignocellulose degradation, and the related lignin degradation enzymes were characterized. However, little was known about their hemicellulases. Read More

Miscanthus×giganteus xylooligosaccharides: Purification and fermentation.

Carbohydr Polym 2016 Apr 23;140:96-103. Epub 2015 Dec 23.

Department of Agricultural and Biological Engineering, University of Illinois at Urbana-Champaign, 1304 W. Pennsylvania Avenue, Urbana, IL 61801, USA. Electronic address:

A procedure was developed to recover xylooligosaccharides (XOS) from Miscanthus×giganteus (M×G) hydrolyzate. M×G hydrolyzate was prepared using autohydrolysis, and XOS rich fractions were acquired using activated carbon adsorption and stepwise ethanol elution. The combined XOS fractions were purified using a series of ion exchange resin treatments. Read More

Combined deacetylation and PFI refining pretreatment of corn cob for the improvement of a two-stage enzymatic hydrolysis.

J Agric Food Chem 2014 May 8;62(20):4661-7. Epub 2014 May 8.

CAS Key Laboratory of Bio-based Materials, Qingdao Institute of Bioenergy and Bioprocess Technology, Chinese Academy of Sciences (CAS) , Qingdao, Shandong 266101, People's Republic of China.

A combined deacetylation and PFI refining pretreatment was applied to corn cob for the improvement of a two-stage enzymatic hydrolysis. In stage 1, the pretreated corn cob was first hydrolyzed by xylanase to produce xylo-oligosaccharides (XOS). In stage 2, the solid residue isolated from stage 1 was further hydrolyzed by cellulase and β-glucosidase. Read More

Structural features and antioxidant activity of xylooligosaccharides enzymatically produced from sugarcane bagasse.

Bioresour Technol 2013 Jan 6;127:236-41. Epub 2012 Oct 6.

Institute of Biomass Chemistry and Technology, Beijing Forestry University, Beijing 100083, China.

Xylooligosaccharides (XOS) were prepared from xylan-rich hemicelluloses isolated by potassium hydroxide from sugarcane bagasse by hydrolysis with crude xylanase secreted by Pichia stipitis. Hydrolysis for 12h produced XOS with a maximum yield of 31.8%, equivalent to 5. Read More

Production of xylooligosaccharides by xylanase from Pichia stipitis based on xylan preparation from triploid Populas tomentosa.

Bioresour Technol 2011 Jul 5;102(14):7171-6. Epub 2011 Apr 5.

Institute of Biomass Chemistry and Technology, College of Material Science and Technology, Beijing Forestry University, Beijing, 100083, China.

Xylooligosaccharides (XOS) with DP 2-4 are important synbiotics used as food ingredients based on its prebiotic characteristics. In this work, the production of XOS from lignocellulosic material was performed by combined chemical-enzymatic methods. Xylan was prepared from triploid Populas tomentosa, and bioconverted into XOS by crude xylanase solution obtained from Pichia stipitis. Read More

Rheofermentometer fermentation and breadmaking characteristics of dough containing xylo-oligosaccharide hydrolyzate from wheat bran.

J Agric Food Chem 2010 Feb;58(3):1878-83

The State Key Laboratory of Food Science and Technology, School of Food Science and Technology, International Exchange and Cooperation Program, Jiangnan University, Wuxi, Jiangsu, 214122, China.

The sugar composition of a xylo-oligosaccharide enzymolysis solution (XES) hydrolyzed from wheat bran and bread containing XES were studied. The effects of the XES on fermentation properties of dough and on bread crumb and crust color characteristics are reported. The composition of sugars was determined by high performance liquid chromatography (HPLC), and the fermentation properties of dough and bread color were determined by Rheofermentometer F3 and Chroma Meter CR-400, respectively.

Value addition to corncob: production and characterization of xylooligosaccharides from alkali pretreated lignin-saccharide complex using Aspergillus oryzae MTCC 5154.

Bioresour Technol 2009 Jan 13;100(2):991-5. Epub 2008 Aug 13.

Fermentation Technology and Bioengineering Department, Central Food Technological Research Institute, Mysore 570 020, Karnataka, India.

Comparison of various pretreatments such as mild alkali/acid treatments and pressure cooking of corncob to expose its lignin-saccharide complex has been carried out to enhance enzymatic hydrolysis of xylan to xylooligosaccharides (XOS). Scanning electron micrographs of lignin-saccharide complex of native and pretreated corncob powder showed that the complex was greatly altered during alkali pretreatment. Hydrolysis of alkali pretreated corncob powder using a commercial endoxylanase produced 81+/-1. Read More
