It seems the big paper about the Arsenic which I’ve talked briefly on the previous post lacks a lot of precision and that the impurities presents in the medium will give room to the possibility that actually the bateria is not using arsenate, but still phosphate.

We were not really convinced at lunch discussion and then it seems we are not the only ones.

More info here. Especially interesting these criticisms . ).3 µM of Phospate is quite a lot in a P-/As+ medium.

I guess there is room to have another look at this bacteria.
