Figure 1. S. hominis induces a stable circumvention of glucose repression.
A) Growth of S. hominis adjacent to [gar−] S. cerevisiae on Gly + GlcN plates induces the yeast cells to acquire a glucosamine-resistant trait. Both organisms are plated in five-fold serial dilutions. B) This trait is stable after hundreds of generations of growth on non-selective media followed by re-testing on Gly + GlcN plates (top).
