Abstract

The recent paper by Wolfe-Simon et al.1 reporting a bacterial strain, which is able to grow in high concentrations of arsenate, apparently in the absence of phosphate, and claims that in this strain arsenate is substituting for phosphate, e.g. in nucleic acids (Figure 1), was highly profiled, attracted broad attention, and almost immediately resulted in heavy scientific criticism (see e.g. 2-7).
