Quad County Corn Processors to trial C5 yeast

Quad County Corn Processors (QCCP), Galva, Iowa, Lallemand Biofuels & Distilled Spirits and Taurus Energy has agreed to trial evaluate C5 yeast "XyloFerm" in the "Cellerate" process on industrial-scale. The trials will begin this month at QCCP's corn ethanol facility in Galva, Iowa and will investigate the scale-up effects on technical and economic factors.

In July 2014, QCCP produced its first gallon of cellulosic ethanol.

Sweden-based biotechnology R&D company Taurus Energy AB has announced that US ethanol producer Quad County Corn Processors (QCCP) is to begin industrial-scale evaluation of its “XyloFerm” C5 yeast strain at QCCP’s 35 million US-gallon per annum (≈132.5 million litre) corn ethanol facility in Galva, Iowa.

After preliminary lab-scale trials of XyloFerm in the “Cellerate” process and obtained GRAS status for the XyloFerm yeast strain, QCCP along with Lallemand Biofuels &
Distilled Spirits and Taurus Energy have agreed to proceed to industrial scale trials, performing a series of tests in 385 000 US gallon (≈ 1.46 million litre) fermentation vessels. The trials will begin this month and will investigate the scale-up effects on technical and economic factors.

– We are excited to now being able to add a C5 yeast as the final piece of the puzzle to maximize plant productivity with our patented “Cellerate” process, said Delayne Johnson, CEO of QCCP in a statement.

Lallemand Biofuels & Distilled Spirits will supply XyloFerm in the form of Stabilized Liquid Yeast (SLY) and dosing system to QCCP for the trial, as well as provide on-site support during the trial. The “Cellerate” process technology enables the production of cellulosic ethanol from corn kernel fiber.

In 2014, Syngenta announced an agreement with Cellulosic Ethanol Technologies, LLC, a wholly-owned subsidiary of QCCP, to be the exclusive marketer of its Cellerate process technology to ethanol plants in North America. The process has been shown to boost ethanol production by 26 percent,  20 percent throughput increase and 6 percent yield increase, when used in combination with Syngenta’s “Enogen” corn.
