It's not an arsenic-based life form
So I'm curious if these cells can survive if reintroduced back in to the wild?"Next, what they did was culture the bacteria in the lab, and artificially jacked up the arsenic concentration, replacing all the phosphate (PO43-) with arsenate (AsO43-). The cells weren't happy, growing at a much slower rate on arsenate than phosphate, but they still lived and they still grew. These are tough critters."That seems to indicate that they wouldn't be able to compete with their cousins outside of a controlled environment.
