On episode #32 of the science show This Week in Microbiology, Vincent, Elio and Michael speak with Rosie Redfield about her evidence that a bacterium cannot grow on arsenic instead of phosphorus.
If you only listen to one episode of TWiM all year, make it this one – Rosie is terrific!
You can find TWiM #32 at microbeworld.org/twim.
Hosts: Vincent Racaniello, Michael Schmidt, Stanley Maloy and Elio Schaechter.
On episode #18 of the podcast This Week in Microbiology, Vincent, Michael, Elio, and Stanley explain how to make the human intestinal commensal and benign laboratory bacterium Escherichia coli K-12 into an invasive organism, and the unearthing of century-old spores in New York City.
