You can write a background of your team here. Give us a background of your team, the members, etc. Or tell us more about something of your choosing.
Introducing a functional light switch into E. coli. The objective in this project is to build and characterise a biological light switch in E.coli. This will involve construction of bacteriophytochrome biobrick parts and heme-oxygenase biobrick parts. In 2010 the Macquarie Team cloned bacteriophytochrome from two sources and showed that one was functionally assembled when incubated with biliverdin. The part created is not directly usable as a biobrick as it contains an internal PstI site and the XbaI biobrick site is missing. The heme-oxygenase clone also contains an internal restriction site which is not compatible with biobrick assembly.	File:Macquarie Australia team.png Your team picture

Safety

1. Would any of your project ideas raise safety issues in terms of: (i) researcher safety, (ii) public safety, or (iii) environmental safety?

When working in any laboratory there are always risks involved that need to be taken into consideration. The Macquarie University 2011 iGEM team will take precautionary measures designed to minimize the risks that could not only potentially affect individual researchers but also the public and the surrounding environment. Each individual team member will complete a laboratory induction-training course and signed an acknowledgment to confirm that they had completed the course. The signed acknowledgement included safety measurements such as where any fire extinguishers and other safety equipment were located as well as the safe use of all machinery in the lab.

Additionally, a seminar is provided by the Macquarie University Chemistry & Biomolecular Science Department’s Technical Manager of Chemical Safety officer – Jenny Minard, to explain Workplace Health and Safety. Topics including the safe storage and documentation of chemicals (such as MSDS’s and risk assessment forms) were discussed in detail.

In the laboratory, we always use protective clothing such as lab coats and gloves when handling all bacterial cultures and DNA samples. The bacterial strains used in our experiments are considered non-hazardous and non-infectious and culture volumes were kept to a minimum so that any risk of spread was minimized. No harmful chemicals will be required for use in our experiments. In particular, ethidium bromide is not used to bind DNA for agarose gel visualization because of its carcinogenic properties. At Macquarie University, the use of ethidium bromide has instead been replaced with newer staining reagents such as GelRed. A Material Safety Data Sheet was completed for all chemicals and reagents used in the laboratory. All workspaces were kept clean to keep sterile conditions and bacterial waste material was auto-claved prior to disposal.

2. Do any of the new BioBrick parts (or devices) that you made this year raise any safety issues?

No, we do not consider our planned cloned genes to raise any Biosafety concerns. The Bacteriophytochrome gene is a pigment-binding protein and the Heme Oxygenase gene is a metabolic enzyme. This means we should not need to document any issues in the registry.

3. Is there a local Biosafety group, committee, or review board at your institution? There is a local Biosafety committee at Macquarie University and all experiments which may involve biosafety risk and/or which involve cloning or transformation of organisms within the University need to obtain approval by the committee before proceeding.

The committee adheres to Australian Government’s legislation: Gene Technology Regulations Act, 2000 . The Biosafety committee granted approval for the 2011 Macquarie University iGEM project prior to commencement of in vivo methods such as cloning and expression (approval number REF: 5201001087EX).

Additionally, as mentioned above the Chemistry & Biomolecular Science Department’s Technical Manager of Chemical Safety officer – Jenny Minard was made fully aware of all chemicals and reagents to be used in the experiment and her approval was obtained.

4. 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?

None as of yet but we hope to have some suggestions at the completion of our project.
