Cutting the Cost of Ethanol, other Biofuels and Gasoline

Submitted by on July 7, 2017 – 1:08 pmNo Comment

(Phys.Org/Rutgers University)  Biofuels like the ethanol in U.S. gasoline could get cheaper thanks to experts at Rutgers University-New Brunswick and Michigan State University.  They’ve demonstrated how to design and genetically engineer enzyme surfaces so they bind less to  stalks and other cellulosic biomass, reducing enzyme  in biofuels production, according to a study published this month on the cover of the journal ACS Sustainable Chemistry & Engineering.

Biomass contains lignin, an organic polymer that binds to and strengthens plant fibers. But lignin inactivates enzymes that bind to it, hampering efforts to reduce enzyme use and costs, according to Chundawat.

The Rutgers and Michigan State University researchers showed how specially designed enzymes (proteins) can limit their binding to and inactivation by lignin. That would ultimately lower enzyme use and make  recycling feasible for biorefineries in the near future, Chundawat said.  READ MORE  Abstract (ACS Sustainable Chemistry & Engineering)
