I have no idea why that would get an “Of course,”. But otherwise, ok, great, if this scales and makes it outside the lab. Which is a big if considering the details of how you starve the bacteria into eating iron quickly aren’t explained for a scale operation.
Very interesting bacteria however, also believed to be responsible for the miracle bleeding of religious monuments.
Why would these tests be conclusive?
Why would these tests be trusted in the first place? (Given that finding a reproducible research paper without errors and bad methodologies is a crapshot)
Was there a conflict of interest that could influence presenting them as safe? (e.g. was this the same lab that developed them and sell them as a solution, or an independent lab with nothing to gain from their success?)
Can these bacteria mutate (and potentially become harmful)?
