LAKEWOOD, Colo., Nov. 19 (UPI) -- Researchers in the biotechnology field in Colorado are working on a pilot scale facility to produce 250,000 gallons of biofuel from cellulosic biomass.

Colorado's ZeaChem Inc. announced work began on a semi-works scale facility to convert renewable biomass into fuels and chemicals.

Their process uses front-end fermentation using acetogen bacteria. These bacteria, unlike yeast, produce no emissions and allow a higher yield than other options, the company said.

Cellulosic biofuels come from switchgrass, woodchips and other similar agricultural residues.

The company said its use of acetogen bacteria in a lab-scale system using cellulosic biomass was promising. It expects its semi-works scale facility to produce 250,000 gallons of biofuel per year.

Corporate executives at ZeaChem said the project was a "milestone" in the push for biofuel production.

Officials expect the facility to go online next year.
