<p>The Rose-Hulman iGEM team has kept safety a top priority since the very early stages of the project. As a result, any project that might have posed as a significant threat to safety was quickly dismissed. During the planning phase of Checkmate, team members brainstormed lab procedures as well as guidelines for plasmid construction to provide a safe and effective workplace. The team used yeast and E.coli in their project, which are both considered Risk Group 1 microorganisms according to the Laboratory Biosafety Manual by the World Health Organization. A Risk Group 1 organism is defined as “(no or low individual and community risk) A microorganism that is unlikely to cause human or animal disease.” The team’s lab is a Basic-Biosafety Level 1 lab, but contains a few aspects from the other categories. The lab does have controlled access, special waste disposal bins, and some biohazard signs. The lab is a school lab that is shared by many professors and students during the school year. These safety practices are rarely in use, and are more of a precaution.Some of the lab methods require using potentially hazardous chemicals that could cause injury to any one of the researchers. Another potential safety risk for researchers results from dealing with microbial agents. While it is unlikely that a researcher would develop an infection from the strains he or she is working with, contagion is still a possible safety concern. To combat these risks, the team was sure to follow all safety protocols, from aseptic techniques to complete labeling. Proper lab attire was worn at all times in the lab. Procedures such as these were taught by the team’s advisor while in the lab.</p>

<p>When considering public safety, it is important to consider every aspect and intermediate step of the project. In Checkmate, the strains of yeast used contain a knockout for an essential amino acid. As a result of this knockout, it is highly unlikely that this yeast could ever escape the lab and be released into the public. However, not all the species involved in the project are so easily controlled. The selection scheme for maintaining the plasmid in E. Coli involved providing the bacteria with antibiotic resistance. In an age where multiple drug resistant bacteria are on the rise and responsible for killing several thousand people a year, the potential of this bacteria escaping and passing this plasmid on to another bacteria cannot be ignored. When handling E. Coli, the team used aseptic techniques and sterilized their equipment.</p>

Researcher, Public, and Environmental Safety

The Rose-Hulman iGEM team has considered safety a top priority since the early stages of project development. As a result, projects that could pose a significant risk were dismissed. Our laboratory space is considered a Basic Biosafety Level 1 laboratory but it does have a few characteristics of higher categories. It has controlled access, biohazard signs and waste disposal bins, and an autoclave. Other safety features are demonstrated below.


All participating students received standard safety and good laboratory practice training as part of their academic laboratory course-work. The Instructor provided more specific safety instruction, as necessary. Proper attire was worn at all times in the laboratory. Gloves and glasses were donned as warranted. The only organisms used in our project are common laboratory strains of Saccharomyces cerevisiae (BY4741 and BY4742) and Escherichia coli (NEB5alpa), which are both considered Risk Group 1 microorganisms according to the Laboratory Biosafety Manual published by the World Health Organization. Group 1 organisms are defined as “no or low individual and community risk, a microorganism that is unlikely to cause human or animal disease.” Aseptic technique is used whenever working with these organisms and any contaminated wastes are sterilized by autoclaving or destroyed by commercial pyrolysis. All laboratory chemicals are stored, handled and used as recommended by the manufacturer, and they are disposed of in accordance with national, state, and local regulations and recommendations. The laboratory space and contents are not accessible by unauthorized personnel. All microbial strains, including bacteria rendered antibiotic resistant by transformation, harbor nutritional auxotrophies or other mutations that mitigate the risk of their growing outside of the laboratory or causing disease in healthy humans or animals. Furthermore, none of our recombinant constructs produce any known contagion or toxin.

BioBrick Safety

None of the BioBrick parts utilized or constructed are known to pose any safety issues. Furthermore, they are well contained by the microbes that harbor them. The risk of unintended transfer to any other organism is minimal.

Biosafety Group

Rose-Hulman does not have a biosafety group, committee or review board other than an Animal Care and Use Committee, which oversees animal research. Safety training and laboratory waste disposal are facilitated by an Environmental Health and Safety Officer, who also serves as a resource for faculty and students.

Future iGEM Safety

The possibility of designing mutually dependent strain/vector systems for routine manipulation and storage of BioBrick parts should be explored.
