<p>As propane is a highly flammable liquid, large-scale microbial production could pose a fire and/or explosion hazard. The production would most likely happen in closed containers with nothing to ignite the gas, easing the problem. However, leaks are always possible: the propane or the bacteria themselves could leak from the microbial container or pipelines to enclosed spaces where ignition is possible. By replacing air, propane could also cause a suffocation danger. To help avoid these problems, it would be beneficial if the propane could be detected. However, propane itself cannot be seen and it has no odour, making detection difficult. Gas molecules with an odour (e.g. ethyl mercaptan) could be added to the purified product and production container. However, this does not allow us to detect the gas if the bacteria leak to produce propane in an enclosed space where no such safety measures are taken.</p> | <p>As propane is a highly flammable liquid, large-scale microbial production could pose a fire and/or explosion hazard.

− | <p>To help detect microbial propane production, it might be thus reasonable to have the propane-producing bacteria also produce a certain scent when propane production is active. This could be achieved by for instance incorporating a banana smell generator device to the same bacterium which is producing propane. Another, perhaps even better option would be to modify the bacteria so that they need to be given certain nutrients not widely available in the environment to survive.</p> | + | <p style="margin-bottom:0;padding-bottom:10%;">To help detect microbial propane production, it might be thus reasonable to have the propane-producing bacteria also produce a certain scent when propane production is active.
