The E. coli strain DH10B and BL21 was used throughout our project. Both are Risk Group 1 laboratory strains of E. coli that have a low, but not nonexistent, virulence. Organisms classified as Risk Group 1 are not known to cause disease in healthy adults. Keeping with registration requirements for Risk Group 1 bacteria, all laboratory work was performed in an environment certified for Biosafety Level 1. Hence, they pose low risk to the safety and health of team members or others working in the lab.

These strains of E. coli are generally not resistant to antibiotics. All bacteria were transformed with bacterial plasmids carrying our desired insert gene and antibiotics resistance to antibiotics commonly used in laboratories for selection (ampicillin, kanamycin, chloramphenicol, etc.), but will not interfere with potential clinical treatment. Neither plasmids nor their insert genes will affect virulence, infectivity, or host range.

We have no intention of releasing any bacteria into the human body or the environment at any point in the iGEM competition. Even if it did "escape' from our lab, the bacteria is effectively harmless; as stated above, neither our plasmids nor our insert genes will affect the virulence, infectivity, or host range.

5. If your project moved from a small-scale lab study to become widely used as a commercial/industrial product, what new risks might arise7 (Consider the different categories of risks that are listed in parts a-d of the previous question.) Also, what risks might arise if the knowledge you generate or the methods you develop became widely available? (Note: This is meant to be a somewhat open-ended discussion question.)

Our aim of this project is to use engineered bacteria to remove excess phosphate from water. It holds hope for utilization in sewage treatment or controlling phosphate levels in aquarium. Reaching that stage, we need to carefully control the engineered bacteria population. Overpopulation of the engineered bacteria might disturb the homeostasis in aquatic system by over-uptaking phosphate.

6. Does your project include any design features to address safety risks? (For example: kill switches, auxotrophic chassis, etc.) Note that including such features is not mandatory to participate in iGEM, but many groups, choose to include them.

We have not yet included any safety features in our project. But we will certainly include these in the future when we are moving in the next step of the project.

Members of our IGEM team members were required to attend a pre-lab training offered by the Department of Biochemistry, the University of Hong Kong before gaining access to the labs. The training was divided into 2 sessions, including safety talk md laboratory inspection, which rise awareness of any potential dangers in the lab to our team members The Department of Biochemistry has provided and maintained a safe environment, in compliance with the Occupational Safety and Health Regulations for every team member.

8. d. According to the WHO Biosafety Manual, what is the BioSafety Level rating of your lab? (Check the summary table on page 3, and the fuller description that starts on page 9.) If your lab does not fit neatly into category 1, 2, 3, or 4, please describe its safety features [see 2013.igem.org/Safety for help].
