Dr. Yong Xu general area is Microbiology and Biotechnology of lignocellulose biorefinery, especially on the biochemical, biofuel and biomaterial making from the polysaccharides constitute.  His group in NJFU is seeking for the novel approach to develop the consolidated bioprocessing for the commercial production of fuel-ethanol, functional oligosaccharides, edible carbohydrate gels, polyols and so on from agro-forest residues and vegetables. In present, they are running a commercial xylo-oligosacchride (XOS) plant to produce functional animal feed additives over 18 years, and also a versatile platform chemical of xylonic acid (XA) was well developed at pilot scale fermentation. By bacterial COS-SSTR bioprocess of whole-cell catalysis with native GRAS strains, 600 g/L xylonite fermentation performance achieved amazingly from xylose, as well as furfural bio-oxidation to over 50 g/L furoic acid  in his lab. The metabolic pathway and sophisticated regulation of various lignocellulosic sugars fermenting strains is also of our highlights.

1) Biorefinery of lignocellulosic biomass for biochemicals, biofuels and biomaterials

3) Whole-cell catalysis and oxidation of saccharides, polyols, furans and so on

4) Consolidated processes of agro-forest and municipal wastes

5) Functional oligosaccharides and its applications

6) Biomodification and bioconversion of natural organic chemicals
