BioCurious indeed. I was cleaning out my old plates from the fridge this afternoon, and came across this fine specimen (pictures are from the top and through the agar, respectively).
The black dot in the middle of the second picture there is curious, as it seems to lie on one of my streak lines. Anyone have any ideas what it might be?
Whatever it is, it either ignores ampicillin, or the amp has long since stopped working. I should also mention that these plates have been sitting in the fridge since the June 2nd.
