"Traditionally,
seaweeds have been cultivated to produce low-priced commodity
products like carrageenan and agar. However, over the past twenty
years, we have developed strain improvement methods that now allow
us to produce seaweed strains that can produce high-value specialty
products or new uses for seaweeds not previously possible.
The current main theme of my lab's research is to use modern molecular
and biotechnology tools to develop new products from seaweeds
for human and fish consumption, as well as for the remediation
of pollutants in the marine environment".
U.S. DEPARTMENT OF AGRICULTURE GRANT:Associate Professor Don Cheney was awarded
a grant in October from the United States Department of Agriculture
(USDA) for the development of new ways to prevent toxic pollutants
like PCBs from getting into our seafood by using seaweeds to
detoxify them. The grant is for $180,000 over two years.

phycological
society of america annual meeting:
Associate Professor Donald Cheney presented an invited talk
entitled “Development of a TNT- Detoxifying Strain of
the Seaweed Porphyra yezoensis Through Genetic Engineering”
at the Annual Meeting of the Phycological Society of America
held in Williamsburg, VA, from August 7-12. The talk was co-authored
by GSAS student Paula Bernasconi and describes their recent
success in expressing a bacterial gene in the seaweed Porphyra
and enabling it to completely remove the explosive compound
TNT from seawater and detoxify it. In related work, Matz Biotechnology
Co-op undergraduate student Jacquelyn Jordan is working in the
Cheney lab this summer on developing seaweed strains that can
detoxify another dangerous toxic pollutant in marine waters,
PCBs.
