Wasn't there recently a discussion of a risk of methanol formation from an ethanol producing strain? I sure hope that none of your strains produce ethanol.
Why not? Ethanol kills competing bacteria and is only produced in microscopic quantities.
Methanol is produced by a lot of bacteria, almost every human produces it within their body.
Slightly different point but many bacteria in us right now also make lipopolysaccharide (LPS). If it were purified and injected iv, the LPS in me could probably kill me 1000 x over.
