Results from growing phosphate-limited GFAJ-1 with and without 40 mM arsenate for 40 hr, in new screw-capped plastic tubes:
I'm away for the rest of the week (Science Online London!), so I put the tubes back into the incubator, to see if the arsenate cultures just grow v-e-r-y s-l-o-w-l-y.
Two weeks later: No, the arsenate cultures didn't grow at all.
