Verdezyne’s Xylose Isomerase Technology Acquired by DuPont Industrial
Patented Technology Enables Conversion of Biomass Sugars to Fuels and
CARLSBAD, Calif. -- December 17, 2012
Verdezyne, Inc., a privately-held industrial biotechnology company focused on
producing renewable chemicals, announced the sale of its proprietary xylose
isomerase technology, enabling the metabolism of 5-carbon sugars, to DuPont
Industrial Biosciences, a world leader in science and innovation.
Under the terms of the sale, DuPont has purchased rights to Verdezyne’s
patented xylose isomerase technology, covered by U.S. Patent Nos. 8,114,974
and 8,093,037, for use in the rapidly-commercializing biofuels and biochemical
fields. This technology allows the fast and complete utilization of
biomass-sourced C5 sugars in production of various products of choice. This
technological breakthrough was highlighted in a recent Journal of Industrial
Microbiology & Biotechnology article published August 2012.
“Verdezyne’s xylose isomerase technology has been shown to have superior
performance compared to alternatives for converting 5-carbon sugar to fuels
and chemicals,” said E. William Radany, Ph.D., president and CEO of Verdezyne.
“We are pleased that a company of DuPont’s stature recognizes the value of our
“Biomass bioprocessing is opening up unique market opportunities across a wide
range of DuPont businesses and the Verdezyne technology is a natural fit for
the company’s cellulosic portfolio,” said John P. Ranieri, vice president,
DuPont Industrial Biosciences. “The addition of this leading xylose isomerase
technology further strengthens DuPont’s leadership in biomass derived sugar
conversion to biofuels and biochemicals.”
