First Woman Member of Patent Club Announced

Dr. Giovanna DeQueiroz received her Patent Club recognition from LSU AgCenter Chancellor Bill Richar

At a ceremony held September 10, 2006, Audubon Post-Doctoral Researcher Giovanna A. DeQueiroz was among two other scientists who were added to the ranks of LSU AgCenter's Patent & PVP Club. Significantly, she is the first woman member out of the 46 currently named. These members represent 10 percent of AgCenter’s research faculties and associates. Giovanna is recognized due to a patent she received for developing a novel biocide called Ox-B while working on her Ph.D. in Food Science at Audubon. Her faculty advisor during this time, Dr. Donal Day, is co-owner of this patent as well.

DeQueiroz started her graduate research in the Fall 2000 and focused on the development of a disinfectant (Ox-B) that could be applied in the food industry to remove and control the growth of biofilms. At the wake of the biological attack on the United States’ postal system in 2001, Ox-B was tested against a wide range of bacterial spores, including Bacillus anthracis (the agent that causes anthrax), which led to encouraging results.

In 2005, a U.S. Patent (6,866,870) was granted for Ox-B. Ox-B is a powerful oxidant that can be used as a cold sterilant or disinfectant of a wide range of Gram-positive and Gram-negative bacteria, whether in the vegetative or spore form, as well as other forms of micro-organisms such as viruses and fungi. Ox-B is also effective in removing bacterial biofilms.

Giovanna A. DeQueiroz graduated in December 2004 and is currently involved in Audubon’s biorefinery project that is funded by the Department of Energy to improve the process to use sugarcane biomass for the conversion of ethanol. A start-up company for Ox-B has been established at the LSU Technology Center, and work is on the way for marketing Ox-B.
