Our host strain (DH10B) was probably the most important factor regarding safety concerns for the environment and the public well-being. As previously mentioned, this E.Coli strain has been engineered for lab use due to its properties of high DNA transformation efficiency and the maintenance of large plasmids. Wild type strains of E.Coli would quickly outcompete DH10B in the event of human or environmental exposure. Initial experiments also seem to indicate that our sensing system strains the metabolism/homeostasis of our DH10B, further reducing its viability both inside and outside the lab environment. Additionally, the plasmids introduced into the DH10B strain do not contain any antibiotic resistances not commonly used for synthetic biology selectivity or otherwise improve the resistance, durability, or reproduction of our organism that would give it unique advantages/characteristics over its native brethren. If ever used in industry, our organism does not require any human or environmental exposure to be effective. It is intended solely for use in controlled environments (i.e. labs, feed reactors, etc.). The ethical implications for our organism are also considered. | Our host strain (DH10B) was probably the most important factor regarding safety concerns for the environment and the public well-being.

Safety Q&A
Would any of your project ideas raise safety issues in terms of: researcher safety, public safety, or environmental safety?
Do any of the new BioBrick parts (or devices) that you made this year raise any safety issues? If yes, did you document these issues in the Registry? How did you manage to handle the safety issue? How could other teams learn from your experience? Is there a local biosafety group, committee, or review board at your institution? What do they think of your project? The Office of Biological Safety (OBS) in the Department of Environment, Health, and Safety at the UW-Madison runs a biological safety course which was mandatory for all iGEM participants. Beyond adhering to all guidelines established in this, we have not further discussed project specifics with the OBS. Do you have any other ideas how to deal with safety issues that could be useful for future iGEM competitions? How could parts, devices and systems be made even safer through biosafety engineering? Maintaining best practices established by biosafety committees is always useful, but there are even more interesting options that could be useful for broader synthetic biology safety down the road. For example, making engineered organisms dependent on non-standard nucleotides or amino acids which are only provided in a laboratory setting could help prevent the accidental release of recombinant organisms.
"The attitudes and actions of those who work in the laboratory determine their own safety, and that of their colleagues and of the community. Laboratory equipment and design can contribute to safety only if they are used properly by people who are genuinely concerned and knowledgeable about safety issues."
