Protein engineering and InnovativeBiomanufacturing
Our mission is to integrate engineering design principle with biology andchemistry to solve the most challenging tasks in the sustainability revolution,such as, terminating the age of crude oil by using renewable energy, feedingthe world with minimum environmental footprints, powering smart phones by metal-freebatteries, etc. We propose to use in vitro synthetic enzymatic pathways forlow-cost biomanufacturing of a lot of products from biofuels, biochemicals,food, nutrients to drugs. Via this platform, we produced 12 H2 perglucose, three times of the yield of microorganisms; transform cellulose tostarch without sugar losses; and developed the most energy dense battery –called sugar biobatteries.
Applicants will conduct the protein-based projects funded by DOE: (1)clone, characterize and express hyperthermostable enzymes in E. coli for in vitro synthetic biologyprojects, (2) increase key enzyme performance by using directed evolutionand/or rational design techniques, and (3) reconstitute in vitro syntheticenzymatic systems for the production of the best transportation fuel –hydrogen, fueling more and more hydrogen fuel cell vehicles. Educational Requirement: Ph.D. degree inBiochemistry (Enzymology), Biomolecular Engineering, Molecular Biology,Microbiology, or relevant majors. The postdoc applicant must have goodpublications as the first author. The relevant experience in proteinengineering and protein characterization is preferred. The applicant should beself-driven, be willing to learn new knowledge and technologies, have strongproblem-solving ability, and have good communication skills.
Position is for one year and will be renewable for at least two years. Ifinterested, please send the cover letter, CV with a list of publications toProf. Dr. Y-H Percival Zhang (Email: ypzhang@vt.edu).Laboratory Website: http://www.sugarcar.com
