Research Areas

Developed a   series of prokaryotic expression system for the production of industrial enzymes

Established   a series of high efficiency E. coli   expression systems using metabolic regulation

Constructed a interspecific   plasmid transfer system in Bacillus   species with the counter-selectable marker mazF

Designed various high   copy and high stable E.   coli-B.subtilis shuttle plasmids

Applied programmable   nucleases (CRISPR/Cas9) for genome editing in Bacillus sp

Discovered,   characterized and engineered various industrial enzymes such as pullulanase, mannase,   catalase, pectase, and so on

Revealed the properties   of CBM68 in the N-terminal of pullulanase

Developed an acidic xylanase   from the metagenomic DNA of cow dung compost and used it to produce xylooligosaccharides   from corncob

Designed a fluorescent   protein marker to reveal the degradation mechanism of corncob hemicellulose

Developed a thermostable   and alkaline xylanase using the combination of ep-PCR and directed mutation

Revealed properties of   the xylan‑binding domain and linker sequence of xylanase XynG1‑1

Firstly accomplished the   overexpression of xylanase in Bacillus   megatherium MS941
