Due to concerns and precautions related to the COVID-19 virus, the Faculty Council HawkTalks presentation will be made available via Zoom at https://nsuok.zoom.us/j/97414225818
Our first presentation of the fall 2021 semester is scheduled for Monday, September 27 from 12 p.m. to 1 p.m. (CST) featuring Dr. Jessica Martin, Associate Dean, Gregg Wadley College of Science and Health Professions, and Professor of Chemistry at Northeastern State University.
Dr. Martin's research interests include: metal ion acquisition by microorganisms, iron binding molecules produced by marine fungi and bacteria, and biomedical applications of metal ion chelators.
The title of her presentation is:
The struggle for iron: metals and microbes in the oceans.
Dr. Martin will highlight her recent research in marine microbes. Iron is required for the growth of nearly all organisms. Although iron is the fourth most abundant element on Earth, it is virtually insoluble under the conditions where most organisms grow (near neutral pH in the presence of oxygen). This fact means that iron is difficult to acquire. Microorganisms have developed an elegant system to obtain iron from the environment: most microbes produce molecules called siderophores which bind and transport iron into the cell.
Dr. Martin and her research students are investigating the structures of siderophores produced by marine microbes, the conditions that affect their production, and applications of these compounds as antibiotics and anticancer drugs. This presentation will encompass the results of these studies.
Please consider joining us virtually for our next HawkTalks presentation on Monday afternoon, September 27 from 12 p.m. - 1 p.m.
