The Chemistry/Biochemistry Department, with funding from the Jean Dreyfus Boissevain Lectureship for Undergraduate Institutes, welcomes Elizabeth Boon '97 from Stony Brook University. She will be giving a talk titled: "When Bacteria Understand the Meaning of NO." Refreshments will be available prior to the talk at 6:45 p.m.
Abstract: Generally, bacteria are thought of as single-celled organisms. In reality, however, most bacteria, most of the time, live in communities called biofilms. Biofilms form on nearly any surface (metal, biological tissue, soil, wood, plastic, etc.) when groups of bacteria stick there and produce a slimy coating. They are a particularly problematic form of bacterial growth because they are up to 1000 times more resistant to antibiotics than bacteria living outside of a biofilm. Biofilms cause hospital-aquired infections, they are a major threat to food and water safety, they clog and corrode oil pipes and fuel lines, and they reduce naval fuel efficiency due to drag from the large communities that form on ship hulls.
Although biofilms are the most abundant mode of bacterial growth, they are also the least understood. Several reports have implicated a molecule called nitric oxide (NO) in the formation of biofilms, although the mechanism of this NO-controlled behavior is unknown. My laboratory has characterized two nitric oxide-binding proteins named H-NOX and NosP. In this talk, I will present our current understanding of the influence of NO on biofilm development and how these studies have pointed to potential new strategies for biofilm prevention.
Elizabeth Boon will also give a talk, titled "Nitric Oxide Signaling in Bacteria: Discovery of a New Mechanism for Regulating Bacterial Biofilms," on Thursday, April 6, at 11:10 a.m. in Higley Hall Auditorium.
